Tweenage angst, RSS feeds, and upcoming talks

Tweenage angst

Do you remember when you were just entering puberty, and absolutely everything was embarrassing? Even your mere existence twisted you in agony?

Well, I just brought my nearly-11-year-old and just-barely-13-year-old sons to their yearly checkups, and let me tell you, it’s painful to be within 10 feet of such exquisite awkwardness: how can you poke and prod this body to some universal understanding of science if I don’t even know its functions or potential grace? If I can’t even imagine it ever being graceful??

RSS feeds

I deleted a post (“Papers I’ve been reading lately”) which had some offending unknown characters that WordPress couldn’t handle, and most people can now read mathbabe again on their readers, except for some reason for people who read mathbabe via WordPress itself. My advice to those people: start using some other reader. Maybe feedly?

Upcoming talks

I’m giving three talks in the next two weeks.

  1. The first one is this Thursday at the Cornell math department, where I’m once again talking about Weapons of Math Destruction.
  2. The second one is in Emanuel Derman’s Financial Engineering Practitioner’s Seminar next Monday at Columbia, where I’ll talk about recommendation systems and MapReduce, taking material from Doing Data Science, specifically the chapters contributed by Matt Gattis and David Crawshaw.
  3. Finally, I’ll be giving the NYC Machine Learning Meetup next Thursday. The announcement of this is going to be posted some time later this morning is now up, and the content will be similar to the Columbia talk.

Aunt Orthoptera: Advice from an Arthropod

Greetings from Aunt Orthoptera!

This week I am guest blogging for Aunt Pythia, answering all of your queries from the perspective of a variety of insect species, naturally.

Dear Aunt Orthoptera,

My friend just started an advice column. She says she only wants “real” questions. But the membrane between truth and falsity is, as we all know, much more porous and permeable than this reductive boolean schema. What should I do?

Sincerely,

Mergatroid

P.S. I have a friend who always shows up to dinner parties empty-handed. What should I do?

Dear Mergatroid,

As I grant your point entirely, I will address only your postscript. What should you do with a friend who shows up to dinner parties empty-handed?  Fill her hands with food.  As an ant, I have two stomachs: a “social stomach,” and a private stomach. When I pass one of my sisters on our path, we touch each other’s antennae and communicate our needs via pheromones. If she is hungry, we kiss, a process unimaginatively called “trophallaxis” by your scientists. I feed her from my social stomach, and I trust she will do the same for me later – or if not her, exactly, another sister in whom the twin hungers for self-interest and interdependence coexist.

Anatomy as metaphor,

Dear Aunt Orthoptera,

I am struggling with emotional loneliness. Do you think it is possible to be happy – or even just productive – in life without a stable romantic relationship? If so, how? I have a couple close friends I can talk with, but they are in their own relationships and they are often too busy to have time to talk. I am in my early thirties and never had a girlfriend despite trying for nearly a decade. I have tried speed-dating, been on eharmony, match, ok cupid, asked friends to set me up, asked out a classmate in grad school, joined meetup groups. I am a nice guy but I have my flaws (nothing horrible) – I am kind of introverted, somewhat boring, and am consumed with my career (I’m untenured). It is so hard to meet people that I am compatible with – especially since I am a shy guy (perhaps it’s not surprising I am a math professor – I LOVE my job, by the way). I found ok cupid to be useful for identifying possibly compatible women but most women don’t respond to my messages. I was lucky to manage to get to go on first (and last) dates with two women I messaged on ok cupid last year, and was interested in going on more dates with both, but both of them declined, even though they both told me I seemed like a good person – “you seem like one of the nicest guys I met” is a direct quote, but that they didn’t feel there was any “chemistry”. This month I have been heartbroken over one of them. All this has been affecting my productivity.

Sincerely,

Singleton

Dear Singleton,

In my anthropological studies of humans, I have observed that you are yearning creatures. Your inexorable primateness destines you to a life of longing for social contact.  As a solitary insect, I both pity and admire this craving for connection with your kind. My advice to you is to have compassion for your fundamental humanness. Your yearning for pair bonding is normal; it’s in your nature to want to entangle yourself with another. As creatures born of DNA, pair bonding operates at both the molecular level (e.g. Cytosine pair-bonds with Guanine) and the organismal level (woman to man, man to man, woman to woman).

I suspect there’s another lonely strand of DNA out there for you, worth waiting for.

Dear Aunt Orthoptera,

Do you have any self-soothing advice for when self-doubt, lack of confidence, and depression begin to take over?

Sincerely,

Feeling Very Small

Dear FVS,

As a tiny butterfly, I can assure you that it is ok to feel small. Here is my advice to you when you feel this way: Don’t just stop and smell the flowers, nuzzle in them.

Let your worries float away for a little while and drift toward the sweetest thing you can find. When viewed through a compound lens, the whole world can look like nectar.

Dear Aunt Orthoptera,

How will you enquire into that which you do not know?

Meno

Excellent question, Musing Meno.

The answer is: with great patience, dear Grasshopper.

Guest Post SuperReview Part III of VI: The Occupy Handbook Part I and a little Part II: Where We Are Now

March 21, 2013 7 comments

Whattup.

Moving on from Lewis’ cute Bloomberg column reprint, we come to the next essay in the series:

The Widening Gyre: Inequality, Polarization, and the Crisis by Paul Krugman and Robin Wells

Indefatigable pair Paul Krugman and Robin Wells (KW hereafter) contribute one of the several original essays in the book, but the content ought to be familiar if you read the New York Times, know something about economics or practice finance. Paul Krugman is prolific, and it isn’t hard to be prolific when you have to rewrite essentially the same column every week; question, are there other columnists who have been so consistently right yet have failed to propose anything that the polity would adopt? Political failure notwithstanding, Krugman leaves gems in every paragraph for the reader new to all this. The title “The Widening Gyre” comes from an apocalyptic William Yeats Butler poem. In this case, Krugman and Wells tackle the problem of why the government responded so poorly to the crisis. In their words:

By 2007, America was about as unequal as it had been on the eve of the Great Depression – and sure enough, just after hitting this milestone, we lunged into the worst slump since the Depression. This probably wasn’t a coincidence, although economists are still working on trying to understand the linkages between inequality and vulnerability to economic crisis.

Here, however, we want to focus on a different question: why has the response to crisis been so inadequate? Before financial crisis struck, we think it’s fair to say that most economists imagined that even if such a crisis were to happen, there would be a quick and effective policy response [editor’s note: see Kautsky et al 2016 for a partial explanation]. In 2003 Robert Lucas, the Nobel laureate and then president of the American Economic Association, urged the profession to turn its attention away from recessions to issues of longer-term growth. Why? Because he declared, the “central problem of depression-prevention has been solved, for all practical purposes, and has in fact been solved for many decades.”

Famous last words from Professor Lucas. Nevertheless, the curious failure to apply what was once the conventional wisdom on a useful scale intrigues me for two reasons. First, most political scientists suggest that democracy, versus authoritarian system X, leads to better outcomes for two reasons.

1. Distributional – you get a nicer distribution of wealth (possibly more productivity for complicated macro reasons); economics suggests that since people are mostly envious and poor people have rapidly increasing utility in wealth, democracy’s tendency to share the wealth better maximizes some stupid social welfare criterion (typically, Kaldor-Hicks efficiency).

2. Information – democracy is a better information aggregation system than dictatorship and an expanded polity makes better decisions beyond allocation of produced resources. The polity must be capable of learning and intelligent OR vote randomly if uninformed for this to work. While this is the original rigorous justification for democracy (first formalized in the 1800s by French rationalists), almost no one who studies these issues today believes one-person one-vote democracy better aggregates information than all other systems at a national level. “Well Leon,” some knave comments, “we don’t live in a democracy, we live in a Republic with a president…so shouldn’t a small group of representatives better be able to make social-welfare maximizing decisions?” Short answer: strong no, and US Constitutionalism has some particularly nasty features when it comes to political decision-making.

Second, KW suggest that the presence of extreme wealth inequalities act like a democracy disabling virus at the national level. According to KW extreme wealth inequalities perpetuate themselves in a way that undermines both “nice” features of a democracy when it comes to making regulatory and budget decisions.* Thus, to get better economic decision-making from our elected officials, a good intermediate step would be to make our tax system more progressive or expand Medicare or Social Security or…Well, we have a lot of good options here. Of course, for mathematically minded thinkers, this begs the following question: if we could enact so-called progressive economic policies to cure our political crisis, why haven’t we done so already? What can/must change for us to do so in the future? While I believe that the answer to this question is provided by another essay in the book, let’s take a closer look at KW’s explanation at how wealth inequality throws sand into the gears of our polity. They propose four and the following number scheme is mine:

1. The most likely explanation of the relationship between inequality and polarization is that the increased income and wealth of a small minority has, in effect bought the allegiance of a major political party…Needless to say, this is not an environment conducive to political action.

2. It seems likely that this persistence [of financial deregulation] despite repeated disasters had a lot do with rising inequality, with the causation running in both directions. On the one side the explosive growth of the financial sector was a major source of soaring incomes at the very top of the income distribution. On the other side, the fact that the very rich were the prime beneficiaries of deregulation meant that as this group gained power- simply because of its rising wealth- the push for deregulation intensified. These impacts of inequality on ideology did not in 2008…[they] left us incapacitated in the face of crisis.

3. Conservatives have always seen seen [Keynesian economics] as the thin edge of the wedge: concede that the government can play a useful role in fighting slumps, and the next thing you know we’ll be living under socialism.

4. [Krugman paraphrasing Kalecki] Every widening of state activity is looked upon by business with suspicion, but the creation of employment by government spending has a special aspect which makes the opposition particularly intense. Under a laissez-faire system the level of employment to a great extend on the so-called state of confidence….This gives capitalists a powerful indirect control over government policy: everything which may shake the state of confidence must be avoided because it would cause an economic crisis.

All of these are true to an extent. Two are related to the features of a particular policy position that conservatives don’t like (countercyclical spending) and their cost will dissipate if the economy improves. Isn’t it the case that most proponents and beneficiaries of financial liberalization are Democrats? (Wall Street mostly supported Obama in 08 and barely supported Romney in 12 despite Romney giving the house away). In any case, while KW aren’t big on solutions they certainly have a strong grasp of the problem.

Take a Stand: Sit In by Phillip Dray

As the railroad strike of 1877 had led eventually to expanded workers’ rights, so the Greensboro sit-in of February 1, 1960, helped pave the way for passage of the Civil Rights Act of 1964 and the Voting Rights Act of 1965. Both movements remind us that not all successful protests are explicit in their message and purpose; they rely instead on the participants’ intuitive sense of justice. [28]

I’m not the only author to have taken note of this passage as particularly important, but I am the only author who found the passage significant and did not start ranting about so-called “natural law.” Chronicling the (hitherto unknown-to-me) history of the Great Upheaval, Dray does a great job relating some important moments in left protest history to the OWS history. This is actually an extremely important essay and I haven’t given it the time it deserves. If you read three essays in this book, include this in your list.

Inequality and Intemperate Policy by Raghuram Rajan (no URL, you’ll have to buy the book)

Rajan’s basic ideas are the following: inequality has gotten out of control:

Deepening income inequality has been brought to the forefront of discussion in the United States. The discussion tends to center on the Croesus-like income of John Paulson, the hedge fund manager who made a killing in 2008 betting on a financial collapse and netted over $3 billion, about seventy-five-thousand times the average household income. Yet a more worrying, everyday phenomenon that confronts most Americans is the disparity in income growth rates between a manager at the local supermarket and the factory worker or office assistant. Since the 1970s, the wages of the former, typically workers at the ninetieth percentile of the wage distribution in the United States, have grown much faster than the wages of the latter, the typical median worker.

But American political ideologies typically rule out the most direct responses to inequality (i.e. redistribution). The result is a series of stop-gap measures that do long-run damage to the economy (as defined by sustainable and rising income levels and full employment), but temporarily boost the consumption level of lower classes:

It is not surprising then, that a policy response to rising inequality in the United States in the 1990s and 200s – whether carefully planned or chosen as the path of least resistance – was to encourage lending to households, especially but not exclusively low-income ones, with the government push given to housing credit just the most egregious example. The benefit – higher consumption – was immediate, whereas paying the inevitable bill could be postponed into the future. Indeed, consumption inequality did not grow nearly as much as income inequality before the crisis. The difference was bridged by debt. Cynical as it may seem, easy credit has been used as a palliative success administrations that been unable to address the deeper anxieties of the middle class directly. As I argue in my book Fault Lines, “Let them eat credit” could well summarize the mantra of the political establishment in the go-go years before the crisis.

Why should you believe Raghuram Rajan? Because he’s one of the few guys who called the first crisis and tried to warn the Fed.

A solid essay providing a more direct link between income inequality and bad policy than KW do.

The 5 Percent by Michael Hiltzik

The 5 percent’s [consisting of the seven million Americans who, in 1934, were sixty-five and older] protests coalesced as the Townsend movement, launched by a sinewy midwestern farmer’s son and farm laborer turned California physician. Francis Townsend was a World War I veteran who had served in the Army Medical Corps. He had an ambitious, and impractical plan for a federal pension program. Although during its heyday in the 1930s the movement failed to win enactment of its [editor’s note: insane] program, it did play a critical role in contemporary politics. Before Townsend, America understood the destitution of its older generations only in abstract terms; Townsend’s movement made it tangible. “It is no small achievment to have opened the eyes of even a few million Americans to these facts,” Bruce Bliven, editor of the New Republic observed. “If the Townsend Plan were to die tomorrow and be completely forgotten as miniature golf, mah-jongg, or flinch [editor’s note: everything old is new again], it would still have left some sedimented flood marks on the national consciousness.” Indeed, the Townsend movement became the catalyst for the New Deal’s signal achievement, the old-age program of Social Security. The history of its rise offers a lesson for the Occupy movement in how to convert grassroots enthusiasm into a potent political force – and a warning about the limitations of even a nationwide movement.

Does the author live up to the promises of this paragraph? Is the whole essay worth reading? Does FDR give in to the people’s demands and pass Social Security?!

Yes to all. Read it.

Hidden in Plain Sight by Gillian Tett (no URL, you’ll have to buy the book)

This is a great essay. I’m going to outsource the review and analysis to:

http://beyoubesure.com/2012/10/13/generation-lost-lazy-afraid/

because it basically sums up my thoughts. You all, go read it.

What Good is Wall Street? by John Cassidy

If you know nothing about Wall Street, then the essay is worth reading, otherwise skip it. There are two common ways to write a bad article in financial journalism. First, you can try to explain tiny index price movements via news articles from that day/week/month. “Shares in the S&P moved up on good news in Taiwan today,” that kind of nonsense. While the news and price movements might be worth knowing for their own sake, these articles are usually worthless because no journalist really knows who traded and why (theorists might point out even if the journalists did know who traded to generate the movement and why, it’s not clear these articles would add value – theorists are correct).

The other way, the Cassidy! way is to ask some subgroup of American finance what they think about other subgroups in finance. High frequency traders think iBankers are dumb and overpaid, but HFT on the other hand, provides an extremely valuable service – keeping ETFs cheap, providing liquidity and keeping shares the right level. iBankers think prop-traders add no value, but that without iBanking M&A services, American manufacturing/farmers/whatever would cease functioning. Low speed prop-traders think that HFT just extracts cash from dumb money, but prop-traders are reddest blooded American capitalists, taking the right risks and bringing knowledge into the markets. Insurance hates hedge funds, hedge funds hate the bulge bracket, the bulge bracket hates the ratings agencies, who hate insurance and on and on.

You can spit out dozens of articles about these catty and tedious rivalries (invariably claiming that financial sector X, rivals for institutional cash with Y, “adds no value”) and learn nothing about finance. Cassidy writes the article taking the iBankers side and surprises no one (this was originally published as an article in The New Yorker).

Your House as an ATM by Bethany McLean

Ms. McLean holds immense talent. It was always pretty obvious that the bottom twenty-percent, i.e. the vast majority of subprime loan recipients, who are generally poor at planning, were using mortgages to get quick cash rather than buy houses. Regulators and high finance, after resisting for a good twenty years, gave in for reasons explained in Rajan’s essay.

Against Political Capture by Daron Acemoglu and James A. Robinson (sorry I couldn’t find a URL, for this original essay you’ll have to buy the book).

A legit essay by a future Nobelist in Econ. Read it.

A Nation of Business Junkies by Arjun Appadurai

Anthro-hack Appadurai writes:

I first came to this country in 1967. I have been either a crypto-anthropologist or professional anthropologist for most of the intervening years. Still, because I came here with an interest in India and took the path of least resistance in choosing to retain India as my principal ethnographic referent, I have always been reluctant to offer opinions about life in these United States.

His instincts were correct. The essay reads like an old man complaining about how bad the weather is these days. Skip it.

Causes of Financial Crises Past and Present: The Role of This-Time-Is-Different Syndrome by Carmen M. Reinhart and Kenneth S. Rogoff

Editor Byrne has amazing powers of persuasion or, a lot of authors have had some essays in the desk-drawer they were waiting for an opportunity to publish. In any case, Rogoff and Reinhart (RR hereafter) have summed up a couple hundred studies and two of their books in a single executive summary and given it to whoever buys The Occupy Handbook. Value. RR are Republicans and the essay appears to be written in good faith (unlike some people *cough* Tyler Cowen and Veronique de Rugy *cough*). RR do a great job discovering and presenting stylized facts about financial crises past and present. What to expect next? A couple national defaults and maybe a hyperinflation or two.

Government As Tough Love by Robert Shiller as interviewed by Brandon Adams (buy the book)!

Shiller has always been ahead of the curve. In 1981, he wrote a cornerstone paper in behavioral finance at a time when the field was in its embryonic stages. In the early 1990s, he noticed insufficient attention was paid to real estate values, despite their overwhelming importance to personal wealth levels; this led him to create, along with Karl E. Case, the Case-Shiller index – now the Case-Shiller Home Prices Indices. In March 2000**, Shiller published Irrational Exuberance, arguing that U.S. stocks were substantially overvalued and due for a tumble. [Editor’s note: what Brandon Adams fails to mention, but what’s surely relevant is that Shiller also called the subprime bubble and re-released Irrational Exuberance in 2005 to sound the alarms a full three years before The Subprime Solution]. In 2008, he published The Subprime Solution, which detailed the origins of the housing crisis and suggested innovative policy responses for dealing with the fallout. These days, one of his primary interests is neuroeconomics, a field that relates economic decision-making to brain function as measured by fMRIs.

Shiller is basically a champ and you should listen to him.

Shiller was disappointed but not surprised when governments bailed out banks in extreme fashion while leaving the contracts between banks and homeowners unchanged. He said, of Hank Paulson, “As Treasury secretary, he presented himself in a very sober and collected way…he did some bailouts that benefited Goldman Sachs, among others. And I can imagine that they were well-meaning, but I don’t know that they were totally well-meaning, because the sense of self-interest is hard to clean out of your mind.”

Shiller understates everything.

Verdict: Read it.

And so, we close our discussion of part I. Moving on to part II:

In Ms. Byrne’s own words:

Part 2, “Where We Are Now,” which covers the present, both in the United States and abroad, opens with a piece by the anthropologist David Graeber. The world of Madison Avenue is far from the beliefs of Graeber, an anarchist, but it’s Graeber who arguably (he says he didn’t do it alone) came up with the phrase “We Are the 99 percent.” As Bloomberg Businessweek pointed out in October 2011, during month two of the Occupy encampments that Graeber helped initiate and three moths after the publication of his Debt: The First 5,000 Years, “David Graeber likes to say that he had three goals for the year: promote his book, learn to drive, and launch a worldwide revolution. The first is going well, the second has proven challenging and the third is looking up.” Graeber’s counterpart in Chile can loosely be said to be Camila Vallejo, the college undergraduate, pictured on page 219, who, at twenty-three, brought the country to a standstill. The novelist and playwright Ariel Dorfman writes about her and about his own self-imposed exile from Chile, and his piece is followed by an entirely different, more quantitative treatment of the subject. This part of the book also covers the indignados in Spain, who before Occupy began, “occupied” the public squares of Madrid and other cities – using, as the basis for their claim on the parks could be legally be slept in, a thirteenth-century right granted to shepherds who moved, and still move, their flocks annually.

In other words, we’re in occupy is the hero we deserve, but not the hero we need territory here.

*Addendum 1: Some have suggested that it’s not the wealth inequality that ought to be reduced, but the democratic elements of our system. California’s terrible decisionmaking resulting from its experiments with direct democracy notwithstanding, I would like to stay in the realm of the sane.

**Addendum 2: Yes, Shiller managed to get the book published the week before the crash. Talk about market timing.

Guest Post SuperReview Part II of VI: The Occupy Handbook Part I: How We Got Here

March 20, 2013 8 comments

Whatsup.

This is a review of Part I of The Occupy Handbook. Part I consists of twelve pieces ranging in quality from excellent to awful. But enough from me, in Janet Byrne’s own words:

Part 1, “How We Got Here,” takes a look at events that may be considered precursors of OWS: the stories of a brakeman in 1877 who went up against the railroads; of the four men from an all-black college in North Carolina who staged the first lunch counter sit-in of the 1960s; of the out-of-work doctor whose nationwide, bizarrely personal Townsend Club movement led to the passage of Social Security. We go back to the 1930s and the New Deal and, in Carmen M. Reinhart and Kenneth S. Rogoff‘s “nutshell” version of their book This Time Is Different: Eight Centuries of Financial Folly, even further.

Ms. Byrne did a bang-up job getting one Nobel Prize Winner in economics (Paul Krugman), two future Economics Nobel Prize winners (Robert Shiller, Daron Acemoglu) and two maybes (sorry Raghuram Rajan and Kenneth Rogoff) to contribute excellent essays to this section alone. Powerhouse financial journalists Gillian Tett, Michael Hilztik, John Cassidy, Bethany McLean and the prolific Michael Lewis all drop important and poignant pieces into this section. Arrogant yet angry anthropologist Arjun Appadurai writes one of the worst essays I’ve ever had the misfortune of reading and the ubiquitous Brandon Adams make his first of many mediocre appearances interviewing Robert Shiller. Clocking in at 135 pages, this is the shortest section of the book yet varies the most in quality. You can skip Professor Appadurai and Cassidy’s essays, but the rest are worth reading.

Advice from the 1 Percent: Lever Up, Drop Out by Michael Lewis

Framed as a strategy memo circulated among one-percenters, Lewis’ satirical piece written after the clearing of Zucotti Park begins with a bang.

The rabble has been driven from the public parks. Our adversaries, now defined by the freaks and criminals among them, have demonstrated only that they have no idea what they are doing. They have failed to identify a single achievable goal.

Indeed, the absurd fixation on holding Zuccotti Park and refusal to issue demands because doing so “would validate the system” crippled Occupy Wall Street (OWS). So far OWS has had a single, but massive success: it shifted the conversation back to the United States’ out of control wealth inequality managed to do so in time for the election, sealing the deal on Romney. In this manner, OWS functioned as a holding action by the 99% in the interests of the 99%.

We have identified two looming threats: the first is the shifting relationship between ambitious young people and money. There’s a reason the Lower 99 currently lack leadership: anyone with the ability to organize large numbers of unsuccessful people has been diverted into Wall Street jobs, mainly in the analyst programs at Morgan Stanley and Goldman Sachs. Those jobs no longer exist, at least not in the quantities sufficient to distract an entire generation from examining the meaning of their lives. Our Wall Street friends, wounded and weakened, can no longer pick up the tab for sucking the idealism out of America’s youth.We on the committee are resigned to all elite universities becoming breeding grounds for insurrection, with the possible exception of Princeton.

Michael Lewis speaks from experience; he is a Princeton alum and a 1 percenter himself. More than that however, he is also a Wall Street alum from Salomon Brothers during the 1980s snafu and wrote about it in the original guide to Wall Street, Liar’s Poker. Perhaps because of his atypicality (and dash of solipsism), he does not have a strong handle on human(s) nature(s). By the time of his next column in Bloomberg, protests had broken out at Princeton.

Ultimately ineffectual, but still better than…

Lewis was right in the end, but more than anyone sympathetic to the movement might like. OccupyPrinceton now consists of only two bloggers, one of which has graduated and deleted all his work from an already quiet site and another who is a senior this year. OccupyHarvard contains a single poorly written essay on the front page. Although OccupyNewHaven outlasted the original Occupation, Occupy Yale no longer exists. Occupy Dartmouth hasn’t been active for over a year, although it has a rather pathetic Twitter feed here. Occupy Cornell, Brown, Caltech, MIT and Columbia don’t exist, but some have active facebook pages. Occupy Michigan State, Rutgers and NYU appear to have had active branches as recently as eight months ago, but have gone silent since. Functionally, Occupy Berkeley and its equivalents at UCBerkeley predate the Occupy movement and continue but Occupy Stanford hasn’t been active for over a year. Anecdotally, I recall my friends expressing some skepticism that any cells of the Occupy movement still existed.

As for Lewis’ other points, I’m extremely skeptical about “examined lives” being undermined by Wall Street. As someone who started in math and slowly worked his way into finance, I can safely say that I’ve been excited by many of the computing, economic, and theoretical problems quants face in their day-to-day work and I’m typical. I, and everyone who has lived long-enough, knows a handful of geniuses who have thought long and hard about the kinds of lives they want to lead and realized that A. there is no point to life unless you make one and B. making money is as good a point as any. I know one individual, after working as a professional chemist prior to college,who decided to in his words, “fuck it and be an iBanker.” He’s an associate at DB. At elite schools, my friend’s decision is the rule rather than the exception, roughly half of Harvard will take jobs in finance and consulting (for finance) this year. Another friend, an exception, quit a promising career in operations research to travel the world as a pick-up artist. Could one really say that either the operations researcher or the chemist failed to examine their lives or that with further examinations they would have come up with something more “meaningful”?

One of the social hacks to give lie to Lewis-style idealism-emerging-from-an attempt-to-examine-ones-life is to ask freshpeople at Ivy League schools what they’d like to do when they graduate and observe their choices four years later. The optimal solution for a sociopath just admitted to a top school might be to claim they’d like to do something in the peace corp, science or volunteering for the social status. Then go on to work in academia, finance, law or tech or marriage and household formation with someone who works in the former. This path is functionally similar to what many “average” elite college students will do, sociopathic or not. Lewis appears to be sincere in his misunderstanding of human(s) nature(s). In another book he reveals that he was surprised at the reaction to Liar’s Poker – most students who had read the book “treated it as a how-to manual” and cynically asked him for tips on how to land analyst jobs in the bulge bracket. It’s true that there might be some things money can’t buy, but an immensely pleasurablemeaningful life do not seem to be one of them. Today for the vast majority of humans in the Western world, expectations of sufficient levels of cold hard cash are necessary conditions for happiness.

In short and contra Lewis, little has changed. As of this moment, Occupy has proven so harmless to existing institutions that during her opening address Princeton University’s president Shirley Tilghman called on the freshmen in the class of 2016 to “Occupy” Princeton. No freshpeople have taken up her injunction. (Most?) parts of Occupy’s failure to make a lasting impact on college campuses appear to be structural; Occupy might not have succeeded even with better strategy. As the Ivy League became more and more meritocratic and better at discovering talent, many of the brilliant minds that would have fallen into the 99% and become its most effective advocates have been extracted and reached their so-called career potential, typically defined by income or status level. More meritocratic systems undermine instability by making the most talented individuals part of the class-to-be-overthrown, rather than the over throwers of that system. In an even somewhat meritocratic system, minor injustices can be tolerated: Asians and poor rural whites are classes where there is obvious evidence of discrimination relative to “merit and the decision to apply” in elite gatekeeper college admissions (and thus, life outcomes generally) and neither group expresses revolutionary sentiment on a system-threatening scale, even as the latter group’s life expectancy has begun to decline from its already low levels. In the contemporary United States it appears that even as people’s expectations of material security evaporate, the mere possibility of wealth bolsters and helps to secure inequities in existing institutions.

Lewis continues:

Hence our committee’s conclusion: we must be able to quit American society altogether, and they must know it.The modern Greeks offer the example in the world today that is, the committee has determined, best in class. Ordinary Greeks seldom harass their rich, for the simple reason that they have no idea where to find them. To a member of the Greek Lower 99 a Greek Upper One is as good as invisible.

He pays no taxes, lives no place and bears no relationship to his fellow citizens. As the public expects nothing of him, he always meets, and sometimes even exceeds, their expectations. As a result, the chief concern of the ordinary Greek about the rich Greek is that he will cease to pay the occasional visit.

Michael Lewis is a wise man.

I can recall a conversation with one of my Professors; an expert on Democratic Kampuchea (American: Khmer Rouge), she explained that for a long time the identity of the oligarchy ruling the country was kept secret from its citizens. She identified this obvious subversion of republican principles (how can you have control over your future when you don’t even know who runs your region?) as a weakness of the regime. Au contraire, I suggested, once you realize your masters are not gods, but merely humans with human characteristics, that they: eat, sleep, think, dream, have sex, recreate, poop and die – all their mystique, their claims to superior knowledge divine or earthly are instantly undermined. De facto segregation has made upper classes in the nation more secure by allowing them to hide their day-to-day opulence from people who have lost their homes, job and medical care because of that opulence. Neuroscience will eventually reveal that being mysterious makes you appear more sexy, socially dominant, and powerful, thus making your claims to power and dominance more secure (Kautsky et. al. 2018).*

If the majority of Americans manage to recognize that our two tiered legal system has created a class whose actual claim to the US immense wealth stems from, for the most part, a toxic combination of Congressional pork, regulatory and enforcement agency capture and inheritance rather than merit, there will be hell to pay. Meanwhile, resentment continues to grow. Even on the extreme right one can now regularly read things like:

Now, I think I’d be downright happy to vote for the first politician to run on a policy of sending killer drones after every single banker who has received a post-2007 bonus from a bank that received bailout money. And I’m a freaking libertarian; imagine how those who support bombing Iraqi children because they hate us for our freedoms are going to react once they finally begin to grasp how badly they’ve been screwed over by the bankers. The irony is that a banker-assassination policy would be entirely constitutional according to the current administration; it is very easy to prove that the bankers are much more serious enemies of the state than al Qaeda. They’ve certainly done considerably more damage.

Wise financiers know when it’s time to cash in their chips and disappear. Rarely, they can even pull it off with class.

The rest of part I reviewed tomorrow. Hang in there people.

Guest Post SuperReview Part I of VI: The Occupy Handbook

March 19, 2013 5 comments

Whassup.

It has become a truism that as the amount of news and information generated per moment continues to grow, so too does the value of aggregation, curation and editing. A point less commonly made is that these aggregators are often limited by time in the sense, whatever the topic, the value of news for the median reader decays extremely rapidly. Some extremists even claim that it’s useless to read the newspaper, so rapidly do things change.  The forty eight hours news cycle, in addition to destroying context, has made it impossible for both reporters and viewers to learn from history. See “Is News Memoryless?” (Kautsky et. al. 2014).

A more promising approach to news aggregation (for those who read the news with purpose) is to organize pieces by subject and publish those articles in a book.  Paul Krugman did this for himself in The Great Unraveling, bundling selected columns from 1999 to 2003 into a single book, with chapters organized by subject and proceeding chronologically. While the rise and rise of Krumgan’s real-time blogging virtually guarantees he’ll never make such an effort again, a more recent try came from uber-journalist Michael Lewis in Panic!: The Story of Modern Financial Insanity.  Financial journalists’ myopic perspective at any given point in time make financial column compilations of years past particularly fun(ny) to read.

Nothing is staler than yesterday’s Wall Street journal (financial news spoils quickly) and reading WSJ or Barron’s pieces from 10 to 20 years ago is just painful.

The title PANIC: The story of modern financial insanity led me to believe the book was about the current crises. The book does say, in very, very fine print “Edited by” Michael Lewis.

-Fritz Krieger, Amazon Reviewer and chief scientist at ISIS

Unfortunately, some philistines became angry in 2008 when they insta-purchased a book called Panic! by Michael Lewis and to their horror, discovered that it contained information about prior financial crises, the nerve of the author to bring us historical perspective, even worse…some of that perspective relating to nations other than the ole’ US of A.

As the more alert readers have noted, almost nothing in the book concerns the 2008 Credit Meltdown, but instead this is merely a collection of news clippings and old magazine articles about past financial crises. You might as well visit a chiropodist’s office and offer them a couple of bucks for their old magazines.

Granted, the articles are by some of today’s finest and most celebrated journalists (although some of the news clippings are unsigned), but do you really want to read more about the 1987 crash or the 1997 collapse of the Thai Baht?

Perhaps you do, but whoever threw this book together wasn’t very particular about the articles chosen. Page 193 reprints an article from “Barron’s” of March, 2000 in which Jack Willoughby presents a long list of Internet companies that he considered likely to run out of cash by 2001. “Some can raise more funds through stock and bond offerings,” he warns. “Others will be forced to go out of business. It’s Darwinian capitalism at work.” True, many of the companies he listed did go belly-up, but on his list of the doomed are

Perhaps because I was abroad for both the initial disaster and the entire Occupation of Zucotti Park, both events have held my attention.  So it is with a mixture of hope and apprehension that I picked up Princeton alum Janet Byrne’s The Occupy Handbook from the public library. The Occupy Handbook is a collection of essays written from 2010 to 2011 by an assortment of first and second-rate authors that attempt to: show what Wall Street does and what it did that led to the most recent crash, explain why our policy apparatus was paralyzed in response to the crash, describe how OWS arose and how it compared with concurrent international movements and prior social movements in the US, and perhaps most importantly, provide policy solutions for the 99% in finance and economics. Janet Byrne begins with a heartfelt introduction:

One fall morning I stood outside the Princeton Club, on West 43rd Street in Manhattan. Occupy Wall Street, which I had visited several times as a sympathetic outsider, has passed its one month anniversary, and I thought the movement might be usefully analyzed by economists and financial writers whose pieces I would commission and assemble into a book that was analytical and- this was what really interested me – prescriptive. I’d been invited to breakfast to talk about the idea with a Princeton Club member and had arrived early out of nervousness.

It seemed a strange place to be discussing the book. I tried the idea out on a young bellhop…

And so it continues. The book is divided into three parts. Part I, broadly speaking, tries to give some economic background on the crash and the ensuing political instability that the crash engendered, up to the first occupation of Zuccotti Park. Part II, broadly speaking, describes the events in Zuccotti Park and around the world as they were in those critical months of fall 2011. Part III, broadly speaking, prescribes solutions to current depression. I say broadly speaking because, as you will see, several essays appear to be in the wrong part and in the worst cases, in the wrong book.

“The problem here is not the message. The problem is the messenger.”

Today’s post is basically going to consist of me wishing I’d written this Gawker piece which was actually written by Hamilton Nolan and was entitled “It Would Be Great if Millionaires Would Not Lecture Us on ‘Living With Less’”.

To enjoy it as much as I did, you’d have to read this New York Times Opinion piece first, in which Graham Hill, who made a bajillion dollars in the dot com era, realizes he had too much stuff and now has less stuff and is telling us how great it is. Most cloying line: “the things I consumed ended up consuming me.”

At the risk of quoting Nolan’s entire article (the title of my post is his), let me start you with this:

There is something about achieving great financial success that seduces people into believing that they are life coaches. This problem seems particularly endemic to the tech millionaire set. You are not simply Some Fucking Guy Who Sold Your Internet Company For a Lot of Money; you are a lifestyle guru, with many important and penetrating insight about How to Live that must be shared with the common people.

We would humbly request that this stop.

I’ll skip over some parts and get to where he talks about Amanda Palmer:

The problem here is not the message. The problem is the messenger. More specifically, it is the messenger using his own life as supporting evidence for the message. Were Graham Hill to simply write a fact-based essay arguing that Americans should cut down on material possessions in order to save the environment and gain peace of mind, he would doubtless hear a chorus of support. But for Graham Hill, a young millionaire who was fortunate enough to sell his “pre-Netscape browser” at the high point of the internet bubble, to say to the average American, “My journey through the perils of great wealth has bestowed me with wisdom that is directly applicable to you” is simply false. It is no wonder that Hill loved the recent TED talk by millionaire musician Amanda Palmer, in which she argued that it was perfectly fair for her to, for example, accept a free night of lodging in the home of poor Honduran immigrants and not pay them for it, because the beauty of her music is payment enough. Both are insulated enough from the realities of personal finance to forget about them entirely.

True! And I’d add more in the Amanda Palmer case. She and I went to the same high school and I have known her since she was in 7th grade.

I’ll tell you what. She’s not your average artist. She’s hugely exhibitionist. This has worked great for her, but is not a typical artistic personality. In fact she’s essentially a cult leader. So yes, when you’re an artist/ cult leader, it makes sense to “let your fans pay you”. But if you’re a typical starving, introverted, sensitive soul, then not so much. How can she speak for all artists and ask them to do stuff just like her? Or rather, why does she think it would scale?

Mind you, I’m guilty of this problem too. When I give advice, which I do all the time, I pretty much always tell people what works for me. But my evidence that the same approach would work for them is slight.

That begs the question, how do we do better than this? How do we tailor our advice to make it useful?

A blogging parliament

Last night I found myself watching Steve Waldman’s talk at the 2011 Economic Bloggers Forum at the Kaufman Foundation. I’m a big fan of Waldman’s blog Interfluidity. His talk was interesting and thought-provoking, like his writing. I suggest you watch it.

After expressing outrage at the failure of control systems and the political system after the financial crisis, Waldman asks the question, why are we where we are? His answer: there’s a monopoly of power in this country even as information itself is increasingly available. The monopoly of power is extremely correlated, of course, to the rising wealth inequality, beautifully visualized in this recent video (h/t Leon Kautsky, Debika Shome) by Politizane.

The solution, he hopes, may include the blogosphere (although it’s not a perfect place either, with its own revolving doors, weird incentives and possibly conflicts of interest). The work of bloggers is valuable social capital, Steve argues, so how do we deploy it?

Steve introduced the concept of policy entrepreneurs, which have three characteristics:

  1. They are sources of information in the form policy ideas. They possible even write laws.
  2. They have some kind of certification in order to cover the policy maker’s ass.
  3. They exert some kind of influence on policy makers, to create incentives for their policy goals.

In other words, a policy entrepreneur is someone in the business of shaping policy makers’ agendas.

If you stop there, you might think “lobbyist,” and you’d be right. But the problem with our current lobbyist system is not the above three characteristics, but rather that it’s a such a closed system. In other words, you essentially need to be rich to be an influential lobbyist (or at least, as an influential lobbyist, you are backed by enormous wealth), but then that increases the monopolistic nature of political power. It doesn’t solve our “monopoly of power” problem.

The question becomes, is there a way for normal people, or groups of people, to be policy entrepreneurs?

One possible solution, Waldman suggests, is to from a parliament of bloggers. Since groups are taken seriously, can bloggers form official groups in which they gain consensus around a topic and issue policy?

An intriguing idea, and I like it because it’s not really abstract: if bloggers decided to try this, they could literally just form a group, call ourselves a name, and start issuing policy proposals. Of course they’d probably not get anywhere unless we had influence or leverage.

Does something like this already exist? The closest thing I can think of is the hacker group Anonymous – although they might not be bloggers, they might be. They’re anonymous. I’m going to guess they are active on the web even if they don’t specifically blog. In any case, let’s see if they qualify as policy entrepreneurs in the above sense.

  • They don’t issue specific policy proposals, but they certainly object clearly to policies they don’t like.
  • Their credentials lie in their unparalleled ability to take control of information systems.
  • Likewise, their leverage is fierce in this domain.

In all, I don’t think Anonymous fits the bill – they’re too devoted to anarchy to deliver policy in the sense that Waldman suggests, and their tools are too crude to make fine points. This might have to do with the nature of hackers in general (keeping in mind that Anonymous stand for something far more extreme than the average hacker), which I read about in an essay by Paul Graham yesterday (h/t Chris Wiggins):

Those in authority tend to be annoyed by hackers’ general attitude of disobedience. But that disobedience is a byproduct of the qualities that make them good programmers. They may laugh at the CEO when he talks in generic corporate newspeech, but they also laugh at someone who tells them a certain problem can’t be solved. Suppress one, and you suppress the other.

 

Here’s another problem: aren’t bloggers in general kind of their own 1%? Is policy via a “parliament of bloggers” not enough of an improvement to the current system of insiders?

What about if Occupy got into the idea of being a vehicle of policy entrepreneurship? Even though we tend not to support specific political candidates in Occupy, we do consistently think about policy and decide whether to endorse a given bill or policy proposal. Could we, instead of commenting on existing policy, start thinking about proposing new policy, even to the point of writing new laws?

On the one hand such work requires enormously long discussions and difficult-to-obtain consensus, but on the other hand we have the knowledge, the abilities, and the moral persuasion. Do we have the influence? And would Occupiers think exerting influence on policy in the current corrupt system tantamount to selling out?

Nasty reader comments and blogging

I’m pretty sure you guys know this already, but I love my regular readers and commenters. It’s a large part of why I blog – I feel like I’m having a super interesting cocktail party every morning in my underwear. I’m investing in the quality of the rest of my day, stealing a moment before my family wakes up so I can articulate one single idea. The payoff is, most of the time, dependably good conversation that lasts all day, or even more than a day, as your comments and emails come in.

Of course, there are sometimes nasty people and comments in addition to thoughtful ones. Not everyone interprets me as trying to figure stuff out, they think I’m being intentionally asinine or manipulative. Or sometimes they just don’t agree with me, and instead of explaining their reasoning they just yell. Or sometimes they are just jerks, getting out their aggression on a stranger.

My first rule is to allow comments that disagree with me, as long as the reasons are articulated and as long as the comment isn’t abusive. Rude is ok, “you are stupid” is not ok.

My second rule is to have a thick skin. I can completely ignore the sentiment of an abusive commenter calling me names, because first of all I’ve heard it all before and second I’m pretty sure it’s not about me.

I’m not saying it doesn’t bother me at all, because obviously it’s a pain to have to go through my email and make sure people are being civil.

For example, whenever I get onto the top 10 of Hacker News, which has been a few times now, I’ve noticed a huge wave of nasty comments. Of course this could be a direct result of how many people I get (thousands per hour), but I don’t think so – the ratio of interesting to abusive comments coming from Hacker News traffic is tiny. It creates nasty work for me, which I feel compelled to do because letting nasty comments stay on my blog makes me feel violated and intentionally misunderstood.

This morning I found this article via Naked Capitalism regarding reader comments, and how nasty ones make subsequent readers evaluate the message differently, and in particular, more negatively. In other words, my intuition was right – it’s super important to curate comments.

My experience with Hacker News has also given me sympathy for Izabella Laba‘s position that she doesn’t accept comments on her blog (read this post for example). She puts herself out there, with strong opinions, and many of her posts are important and thought-provoking. And by the same token people can get pretty threatened by what she has to say. I can well imagine what her experience has been. What if every day was a Hacker News day? What if a majority of comments contained ridiculous and personal attacks? Yuck.

Makes me even more grateful to have you guys.

Prices in the junk bond market

There are various ways of deciding how valuable something is. People spend some amount of time talking about “the current value of future earnings til the end of time” as a rule-of-thumb measurement. That sometimes works (i.e. jives with what the selling price is), but it’s certainly not robust – in a given case, plenty of people think there’s a good reason a stock should be worth more than that, if their personal growth projections are rosy (you could argue that they are still valuing future earnings, but they’ve got a different projection than, say, the current dividends continued as is. Another possibility is that they’re simply valuing future values coming from other people). Similarly, some stocks are underpriced with respect to this baseline. Could it be that they’re cooking their books? If they don’t last til the end of time then they could hardly be making earnings til then (Groupon).

Of course when you go down that road, nothing lasts til the end of time. Never mind companies, the industry in which the company sits will be dead before too long unless it’s food or cosmetics.

Anyway, throw out the future earnings price for a moment, and replace it by something else entirely: there’s a certain amount of money invested in the (international) market at a given moment, and it has to go somewhere. I think of it as a big pot that sloshes around and achieves equilibrium depending on various things like relative interest rates in different countries, and to a lesser extent, regulation in different countries and access to markets. Like, the carry trade is kind of a big deal, and depends almost entirely on the Japanese interest rate being tiny.

Of course it’s not really that simple, since people can and do remove money from the market at certain times – it’s not a closed system. But not as much money is removed as you might think, because if you think about it, lots of people have set up their livelihoods to be investing large pots of money, so they need to appear busy.

Articles like this one from Bloomberg make me think about the “where should we put our money that we need to invest somewhere?” effect is particularly strong right now. We see people “chasing yield” in the junk bond market, buying junk bonds that have positive yields because their options are limited while the Fed keeps the rates really low (this is not a side-effect of the Fed’s keeping the rates low, it’s their goal. They want people to invest in financing businesses, which is what buying junk bonds is).

But they (the investors) all want the same stuff, so the prices are too low high, which is another way of saying the yields are a lot lower than they’d otherwise be if there were other things to buy. This might be a good example of where the price of junk debt is not particularly good at exposing the actual risk of default. Well, it might be an ok indicator of the very short-term default rate, but that’s just because money is so cheap right now, businesses in trouble can just borrow more. It’s kind of a set-up for a bubble.

The article makes the point that once the Fed raises rates, people will flee this market, since they will actually be able to make money again with less risky bonds. The slower actors will be left with much-reduced-in-value junk debt. The big pot of money which is the market will have an entirely new equilibrium point, and there will be lots of death and destruction in the transition. It’s become even more crucial than usual to time the Fed’s moves, but keep in mind money managers are going to stay in there as long as they possibly can because they don’t want to miss yield while their bonuses depend on it (“opportunity costs”). It’s a game of chicken.

Staying with the meta-analysis, can someone do a back-of-the-envelope estimate of how much built-in interest rate risk we’ve taken on by the issuance of so much junk debt in the overall international portfolio? Is it sizeable?

Is mathematics a vehicle for control fraud?

Bill Black

A couple of nights I ago I attended this event at Columbia on the topic of  “Rent-Seeking, Instability and Fraud: Challenges for Financial Reform”. 

The event was great, albeit depressing – I particularly loved Bill Black‘s concept of control fraud, which I’ll talk more about in a moment, as well as Lynn Turner‘s polite description of the devastation caused by the financial crisis.

To be honest, our conclusion wasn’t a surprise: there is a lack of political will in Congress or elsewhere to fix the problems, even the low-hanging obvious criminal frauds. There aren’t enough actual police to take on the job of dealing with the number of criminals that currently hide in the system (I believe the statistic was that there are about 1,000,000 people in law enforcement in this country, and 2,500 are devoted to white-collar crime), and the people at the top of the regulatory agencies have been carefully chosen to not actually do anything (or let their underlings do anything).

Even so, it was interesting to hear about this stuff through the eyes of a criminologist who has been around the block (Black was the guy who put away a bunch of fraudulent bankers after the S&L crisis) and knows a thing or two about prosecuting crimes. He talked about the concept of control fraud, and how pervasive control fraud is in the current financial system.

Control Fraud

Control fraud, as I understood him to describe it, is the process by which a seemingly legitimate institution or process is corrupted by a fraudulent institution to maintain the patina of legitimacy.

Once you say it that way, you recognize it everywhere, and you realize how dirty it is, since outsiders to the system can’t tell what’s going on – hey, didn’t you have overseers? Didn’t they say everything was checking out ok? What the hell happened?

So for example, financial firms like Bank of America used control fraud in the heart of the housing bubble via their ridiculous accounting methods. As one of the speakers mentioned, the accounting firm in charge of vetting BofA’s books issued the same exact accounting description for many years in the row (literally copy and paste) even as BofA was accumulating massive quantities of risky mortgage-backed securities (update: I’ve been told it’s called an “Auditors Report” and it has required language. But surely not all the words are required? Otherwise how could it be called a report?). In other words, the accounting firm had been corrupted in order to aid and abet the fraud.

“Financial Innovation”

To get an idea of the repetitive nature and near-inevitability of control fraud, read this essay by Black, which is very much along the lines of his presentation on Tuesday. My favorite passage is this, when he addresses how our regulatory system “forgot about” control fraud during the deregulation boom of the 1990’s:

On January 17, 1996, OTS’ Notice of Proposed Rulemaking proposed to eliminate its rule requiring effective underwriting on the grounds that such rules were peripheral to bank safety.

“The OTS believes that regulations should be reserved for core safety and soundness requirements.  Details on prudent operating practices should be relegated to guidance.

Otherwise, regulated entities can find themselves unable to respond to market innovations because they are trapped in a rigid regulatory framework developed in accordance with conditions prevailing at an earlier time.”

This passage is delusional.  Underwriting is the core function of a mortgage lender.  Not underwriting mortgage loans is not an “innovation” – it is a “marker” of accounting control fraud.  The OTS press release dismissed the agency’s most important and useful rule as an archaic relic of a failed philosophy.

Here’s where I bring mathematics into the mix. My experience in finance, first as a quant at D.E. Shaw, and then as a quantitative risk modeler at Riskmetrics, convinced me that mathematics itself is a vehicle for control fraud, albeit in two totally different ways.

Complexity

In the context of hedge funds and/or hard-core trading algorithms, here’s how it works. New-fangled complex derivatives, starting with credit default swaps and moving on to CDO’s, MBS’s, and CDO+’s, got fronted as “innovation” by a bunch of economists who didn’t really know how markets work but worked at fancy places and claimed to have mathematical models which proved their point. They pushed for deregulation based on the theory that the derivatives represented “a better way to spread risk.”

Then the Ph.D.’s who were clever enough to understand how to actually price these instruments swooped in and made asstons of money. Those are the hedge funds, which I see as kind of amoral scavengers on the financial system.

At the same time, wanting a piece of the action, academics invented associated useless but impressive mathematical theories which culminated in mathematics classes throughout the country that teach “theory of finance”. These classes, which seemed scientific, and the associated economists described above, formed the “legitimacy” of this particular control fraud: it’s math, you wouldn’t understand it. But don’t you trust math? You do? Then allow us to move on with rocking our particular corner of the financial world, thanks.

Risk

I also worked in quantitative risk, which as I see it is a major conduit of mathematical control fraud.

First, we have people putting forward “risk estimates” that have larger errorbars then the underlying values. In other words, if we were honest about how much we can actually anticipate price changes in mortgage backed securities in times of panic, then we’d say something like, “search me! I got nothing.” However, as we know, it’s hard to say “I don’t know” and it’s even harder to accept that answer when there’s money on the line. And I don’t apologize for caring about “times of panic” because, after all, that’s why we care about risk in the first place. It’s easy to predict risk in quiet times, I don’t give anyone credit for that.

Never mind errorbars, though- the truth is, I saw worse than ignorance in my time in risk. What I actually saw was a rubberstamping of “third part risk assessment” reports. I saw the risk industry for what it is, namely a poor beggar at the feet of their macho big-boys-of-finance clients. It wasn’t just my firm either. I’ve recently heard of clients bullying their third party risk companies into allowing them to replace whatever their risk numbers were by their own. And that’s even assuming that they care what the risk reports say.

Conclusion

Overall, I’m thinking this time is a bit different, but only in the details, not in the process. We’ve had control fraud for a long long time, but now we have an added tool in the arsenal in the form of mathematics (and complexity). And I realize it’s not a standard example, because I’m claiming that the institution that perpetuated this particular control fraud wasn’t a specific institution like Bank of America, but rather then entire financial system. So far it’s just an idea I’m playing with, what do you think?

Ninja Warrior – Sasuke

If you having trouble falling asleep some time, but you’re too tired to actually read things that require anything more than amusement, amazement, and bafflement, then let me suggest you watch a bit of Sasuke, also known as the Japanese version of American Ninja Warrior (hat tip Johan de Jong).

I dare you to watch only five minutes of the following final round (here’s the competition from the beginning if you are hardcore) in which the last surviving American gets expelled almost immediately and it’s down to the last few Japanese competitors. It’s extra fun for it to be in Japanese because then you get to add in dubbing, kind of like Iron Chef used to be back before it became Americanized:

Looking for ideas for a mathbabe logo

Apologies for the self-indulgent posts two days in a row, but I’m looking for ideas for a mathbabe logo. I have a coffee mug and a shirt already, because for whatever reason zazzle.com already had a mathbabe logo when I checked, and it looks like this:

Mysteriously found on Zazzle.com

Mysteriously found on Zazzle.com

The problem is that I’m not exactly a pink frilly person, although I’ve made do with a black T-shirt background.

And I need this why? Because I’m thinking of making some mathbabe t-shirts and paraphernalia to give to people and/or sell (partly because I’m jealous of the stack project t-shirts I see all over the neighborhood).

Anyway, if anyone has ideas for a new graphic, or a designer friend who needs money (not too much I hope), or better yet a sample graphic, please get in touch with me, thanks! My email is on the “About” page.

Singularity Institute and Google: what are their plans?

A few days ago I read a New York Times interview of Ray Kurzweil, who thinks he’s going to live forever and also claims he will cure cancer if and when he gets it (his excuse for not doing it in his spare time now: “Well, I mean, I do have to pick my priorities. Nobody can do everything.”). He also just got hired at Google.

As a joke I suggested that Google employees read the interview and then quit their job.

My reasoning went like this: if someone who is clearly narcissistic and delusional gets hired by your company, and given a position much higher than you (Kurzweil’s title is “Director of Engineering,” and although that doesn’t mean he is in charge of everyone in Engineering, it is nonetheless a high position), then you can give up all hope of ever being promoted based on your actual contributions. Companies have natural stages in their lives, and Google has evidently reached the stage of hiring “thought leaders” who nobody could actually work with but are somehow aligned with the agenda of the leadership.

Since then I’ve learned a bit more about Kurzweil, and about the Singularity Institute (based on the idea that computers will become self-aware and super-intelligent which will culminate in a very special moment for some parts of humanity), and the related ideologies of Futurism (fetishizing technology), Transhumanism (the idea we are going to be immortal), and “human rationality” as espoused by the blog lesswrong. Note I usually link to wikipedia articles but in the above cases, especially for the Singularity Institute, the associated wikipedia article is suspiciously sanitized of actual information.

A lot of my research is covered in this New York Times article from 2010 about the Singularity Institute’s opening. In particular it describes the close relationship between the Google royalty and the Singularity Institute. Suffice it to say there is a serious relationship between the founders of Google and this Institute.

But I’m not writing this to point out the number of ties between those institutions – this is well-documented in the above article and has only grown more obvious with the recent acquisition of Kurzweil.

And I’m also not writing to suggest that the Singularity Institute is a cult. I honestly think they make the case better than I could when the Executive Director, Luke Meuhlhauser, posts things entitled “So You Want to Save the World” wherein he states:

The best way for most people to help save the world is to donate to an organization working to solve these problems, an organization like the Singularity Institute or the Future of Humanity Institute.

Don’t underestimate the importance of donation. You can do more good as a philanthropic banker than as a charity worker or researcher.

It’s really that last sentence I want to focus on. It’s where the creepy elitism of this ideology comes out. Because make no mistake, this is a massive circle jerk for techie men (mostly men) to think of themselves as joining up with gods due to their superior intelligence and creativity.

Whatever, I’ve been around nerds all my life, and it’s nothing new to me that some of them want intelligence to count for more than just getting an edge in education and the job market. Somehow this ideology creates a hunger for much more than that: immortality, for one, and the feeling of being chosen.

You see, I believe in incentives. I want to prepare myself for what people will do next based on what I think their incentives are, and these Singularity Institute guys are on the one hand pretty hardcore with their beliefs, and on the other hand infiltrating Google, which is an incredibly powerful force in an essentially unregulated domain. So what are their plans?

Just to give you an idea, check out this line from Vernor Vinge’s now famous 1993 essay on the Singularity (emphasis mine):

Suppose we could tailor the Singularity. Suppose we could attain our most extravagant hopes. What then would we ask for: That humans themselves would become their own successors, that whatever injustice occurs would be tempered by our knowledge of our roots. For those who remained unaltered, the goal would be benign treatment (perhaps even giving the stay-behinds the appearance of being masters of godlike slaves). It could be a golden age that also involved progress (overleaping Stent’s barrier). Immortality (or at least a lifetime as long as we can make the universe survive [9] [3]) would be achievable.

A few comments:

  • Vinge didn’t think the singularity was inevitable when he wrote that.
  • Vinge recently spoke at the October 2012 Singularity Summit hosted by the Singularity Institute (along with Director of Research from Google, Peter Norvig). Here’s a video.
  • The “stay-behinds” are the people who don’t get to transcend with the machines if and when the Singularity occurs.

Personally, I have fun thinking about the Singularity. I think it’s already happened, in fact, and my best argument for why machines are already smarter than us is this: when someone much smarter than you is saying something, maybe not to you, you don’t always know that that person is smarter – sometimes it just feels like they’re being confusing. But that’s exactly how we humans all feel about this mess we’ve made with the financial system: we are confused by it, we don’t understand it, and moreover we have no hope of dumbing it down to our level. That’s a sign it is superintelligent. Maybe not self-aware, but on the other hand how can you test that? In this light, the “stay-behinds” are Canadians.

Also, I totally believe everyone has the right to their own opinions, and for that matter they have a right to join a cult if they feel like it. In fact people who want to live forever, you could argue, are more likely to take care of the environment and their own children, because those are major investments for them.

On the other hand, what is their plan for the rest of us? Is it to, like Vinge says, give us the appearance of being masters of godlike slaves? Are those slaves our smart phones? Are we being intentionally shepherded into an artificial existence of play-power? Because I’ve suspected that very thing ever since I read the Filter Bubble. What else, especially in the context of the ongoing competition for resources?

The Singularity may never happen, or it may already have happened- that’s irrelevant to me. My thought experiment is this:

What are the consequences of a bunch of people who believe in something called the Singularity and who are also in control of a powerful company?

This is what it feels like to be a snob

Got home from Nebraska last night, and I’ve learned an important lesson about how it feels to be a snob. Because, as it turns out, I’m unequivocally a snob in ways I didn’t even realize.

So, I couldn’t find good coffee in Lincoln. That is, in the hotel they had a coffee maker with a tiny pod, and I made myself two cups the first morning I got there, then I went downstairs and drank two more cups of the free coffee you get with the free breakfast and I swear it was hot water.

Then I looked around and wondered, where can I get something with caffeine in it?? After asking a few people this question, I suddenly realized: this is what it feels like to be a snob. Internally it feels weird that other people don’t have the same standards, but externally it looks like a smart-ass New Yorker complaining about the quality of free things.

Next: people would be walking around the hotel in what seemed like pajamas. Not the mathematicians, who came from everywhere, but the other guests in the hotel. They were young, maybe in college, and I swear they were wearing pajamas all the time. Sometimes they switched it up and wore clothes you might wear when watching a football game on the sofa.

Then I realized: people in New York spend way too much time getting all dolled up, and I used to know that, but nowadays I’m just used to it. So this is what is feels to be a snob.

Good to know, because:

  1. Next time someone who’s a huge snob talks to me I’ll have more empathy and explain the situation in clear sentences: you are looking like a snob because you have different standards, and the sooner you understand that the better for everyone.
  2. Next time I travel I plan to bring my own coffee and possibly even my own coffee maker, which I used to think is crazy  snobby but now I get it – it actually saves time versus searching on foot in the winter for a good cup of coffee in a town you are unfamiliar with. I’m embracing my snobbery, people.
  3. Although then again maybe I’ll just bring a big ol’ vat of Nodoz.

The Yarn Whisperer

Everyone should get a yarn whisperer. Here’s mine:

Yes, she has her knitting project in that white bag, just in case there's a 2-minute lull

Yes, she has her knitting project in that white bag, just in case there’s a 2-minute lull

What does a yarn whisperer provide, you ask? Among other things:

  1. continuous advice on how to use the yarn you have,
  2. unadulterated enabling of buying more yarn that you don’t need, and
  3. companionship to annual “yarn events” (where #2 above takes place with wild abandon)

Yesterday me and my yarn whisperer went to Knitting Vogue Live (or VKL for those in the know), held at the Times Square Marriott. It was extra fancy, by knitting standards, which if you don’t know what that is, think Star Trek conventions for the knitterlati.

We had our very own knitting fashion show:

We are all looking at that hat.

We are all looking at that scrumptious hat.

Just take another look at this packed crowd:

A nicer group of frumpy crafty women from Connecticut you'll never see

I was amazed to meet Alasdair Post-Quinn:

The number of scarf configurations is larger than the number of atoms in the universe.

Alisdair is the author of the book “Extreme double knitting”:

You gotta say "EXTREME" like a Monster Truck Rally is coming to town.

You gotta say “EXTREME” like a Monster Truck Rally is coming to town.

And he does incredible double-knitting work. I told him he’s a mathematician, even if he wasn’t trained. Here are some examples:

That's *three strands* on the Escher-like scarf on the left!

That’s *three strands* on the Escher-like scarf on the left!

And here’s the back of the trees one:

I've always wanted to knit realistic trees.

I got a huge kick out of staring at people’s backs yesterday:

Don't worry, I asked before I took this picture.

Don’t worry, I asked before I took this picture.

I'm not a fan of glitter but if you go for it, you gotta GO FOR IT

I’m not a fan of glitter but if you go for it, you gotta GO FOR IT

I also enjoyed meeting this man with ENORMOUS KNITTING NEEDLES:

Sorry for the blur, couldn't stop giggling. Note his vest, also made from enormous yarn

Sorry for the blur, couldn’t stop giggling. Note his vest, also made from enormous yarn.

And the yarn sculptures were super:

Is it art or is it clothing?

Take this off before eating soup.

Thank you, oh yarn whisperer!

Quantifying the pull of poverty traps

In yesterday’s New York Times Science section, there was an article called “Life in the Red” (hat tip Becky Jaffe) about people’s behavior when they are in debt, summed up by this:

The usual explanations for reckless borrowing focus on people’s character, or social norms that promote free spending and instant gratification. But recent research has shown that scarcity by itself is enough to cause this kind of financial self-sabotage.

“When we put people in situations of scarcity in experiments, they get into poverty traps,” said Eldar Shafir, a professor of psychology and public affairs at Princeton. “They borrow at high interest rates that hurt them, in ways they knew to avoid when there was less scarcity.”

The psychological burden of debt not only saps intellectual resources, it also reinforces the reckless behavior, and quickly, Dr. Shafir and other experts said. Millions of Americans have been keeping the lights on through hard times with borrowed money, running a kind of shell game to keep bill collectors away.

So what we’ve got here is a feedback loop of poverty, which certainly jives with my observations of friends and acquaintances I’ve seen who are in debt.

I’m guessing the experiments described in the article are not as bad as real life, however.

I say that because I’ve been talking on this blog as well as in my recent math talks about a separate feedback loop involving models, namely the feedback loop whereby people who are judged poor by the model are offered increasingly bad terms on their loans. I call it the death spiral of modeling.

If you think about how these two effects work together – the array of offers gets worse as your vulnerability to bad deals increases – then you start to understand what half of our country is actually living through on a day-to-day basis.

As an aside, I have an enormous amount of empathy for people experiencing this poverty trap. I don’t think it’s a moral issue to be in debt: nobody wants to be poor, and nobody plans it that way.

This opinion article (hat tip Laura Strausfeld), also in yesterday’s New York Times, makes the important point that listening to a bunch of rich, judgmental people like David Bach, Dave Ramsey, and Suze Orman telling us it’s our fault we haven’t finished saving for retirement isn’t actually useful, and suggest we individually choose a money issue to take charge and sort out.

So my empathetic nerd take on poverty traps is this: how can we quantitatively measure this phenomenon, or more precisely these phenomena, since we’ve identified at least two feedback loops?

One reason it’s hard is that it’d be hard to perform natural tests where some people are submitted to the toxic environment but other people aren’t – it’s the “people who aren’t” category that’s the hard part, of course.

For the vulnerability to bad terms, the article describes the level of harassment that people receive from bill collectors as a factor in how they react, which doesn’t surprise anyone who’s ever dealt with a bill collector. Are there certain people who don’t get harassed for whatever reason, and do they fall prey to bad deals at a different rate? Are there local laws in some places prohibiting certain harassment? Can we go to another country where the bill collectors are reined in and see how people in debt behave there?

Also, in terms of availability of loans, it might be relatively easy to start out with people who live in states with payday loans versus people who don’t, and see how much faster the poverty spiral overtakes people with worse options. Of course, as crappy loans get more and more available online, this proximity study will become moot.

It’s also going to be tricky to tease out the two effects from each other. One is a question of supply and the other is a question of demand, and as we know those two are related.

I’m not answering these questions today, it’s a long-term project that I need your help on, so please comment below with ideas. Maybe if we have a few good ideas and if we find some data we can plan a data hackathon.

Leaning into the pain

I didn’t know Aaron Swartz personally, but I’ve been reading about his life and death (hat tip Suresh Naidu) in the past day and he was clearly a remarkable thinker. His writing about procrastination in the context of computer programming (hat tip Matt Stoller) is particularly resonant. From the essay:

Yes it’s painful, but the trick is to make that mental shift. To realize that the pain isn’t something awful to be postponed and avoided, but a signal that you’re getting stronger — something to savor and enjoy. It’s what makes you better.

Pretty soon, when you start noticing something that causes you psychic pain, you’ll get excited about it, not afraid. Ooh, another chance to get stronger. You’ll seek out things you’re scared of and intentionally confront them, because it’s an easy way to get the great rewards of self-improvement. Dalio suggests thinking of each one as a puzzle, inside of which is embedded a beautiful gem. If you fight through the pain to solve the puzzle, you unlock it and get to keep the gem.

The trick is: when you start feeling that psychological pain coming on, don’t draw back from it and cower — lean into it. Lean into the pain.

You should really read the whole thing. Aaron explains something about good coding practices that elevates coding to a philosophical activity (which it deserves but rarely achieves) and, like any good philosophy, makes us reconsider how we spend our time and what we choose to do with it.

I know exactly what pain I’m leaning into this morning.
