Why the NFL conversation about Ray Rice is so important to me

September 18, 2014 11 comments

My first memory is of my father throwing a plate of eggs at my mother’s head, like a frisbee. My mother had to duck to get out of the way, and the plate exploded on the wall behind her. His eggs hadn’t been cooked well enough, and this was his way of expressing that to my mother, who had cooked them. Then he punched his hand through a glass window. Blood and glass fragments were everywhere. I was 4 years old. I remember running to my bed and crying, and the already familiar feeling of hiding in fear.

My mother was a battered woman who didn’t leave her abuser. And that meant a bunch of things for her and for me and my brother. I cannot explain her reasoning, because I was a small child when most of the abuse occurred. But I can tell you it’s common enough, and it’s not even that hard to understand.

One of the aspects of this decision – to stay with your abuser or not – that I haven’t been hearing a lot of recently, in this whole Ray Rice-inspired nationwide conversation about violence against women, is the economics of it. The worst of my father’s behavior happened when he was unemployed and desperately unhappy with how his life was turning out. Once he got on his feet again he didn’t take stuff out on his wife as much or as often. I imagine that is typical, but what it means is that it’s extra hard to imagine managing a second household, with small children, on one salary, when it’s already a huge struggle to manage one. The economic reality of leaving your husband has to be understood.

Even so, the abuse didn’t completely stop, and it’s not like my mother never considered leaving my father. I remember I went away for a month, to communist Budapest, when I was turning 13, the summer of 1985. When I came back my mother told me that my father had pushed her down the stairs. Then she asked me if she should leave him. I said yes, but then she didn’t do it.

I will probably never really forgive her for asking me that, for putting that kind of responsibility on a child like that, and then not following through. Especially now that I have kids of my own that age, it seems outrageous to put that kind of decision on their plate, or even seem to. It was my last day of childhood, the day I realized there were no responsible people in my family, and that I would have to step up and be the person who negotiated reasonable boundaries or, failing that, call the cops. From then on I was my mother and my brother’s protector.

If anyone ever asks me why I am not intimidated by anyone, I think of that moment. When you are a 13-year-old girl who has decided to stand up for your mother and brother against a large and very strong man, who often becomes an enraged and unreasonable bully, you forget about fear and intimidation, because it’s just something you cannot think about.

Many years later, after I left college, my father engaged me in a series of ritualized revisionist history lessons. Every Christmas, every Thanksgiving, maybe even on July 4th, he would bring up the bad old days and he’d mention how much I’d hated him when I was a teenager, and how he hadn’t deserved it, and how even when he’d been abusive to my mother, she had hit him first, and he hadn’t really wanted to do it but there it is. He often distorted facts, and he never explained why he was doing this.

It always sounded so bizarre to me – how could it matter that my mother had hit him first, not to mention that it was unbelievably hard to imagine? How could that be an excuse for what kind of fear and rage he had manifested on her body and on our family for so long? Answer: it isn’t an excuse.

It was very confusing, these inaccurate family history lessons in sermon form. It made me so angry I never could do anything except stay silent. I didn’t even correct him when he lied about the details, because he was evidently saying all of this more for him than for me.

It took me years to figure out why this conversation kept happening, but I think I finally know now. He was working through his guilt with me as his chosen audience. He was, in a sense, asking for my forgiveness. I never gave it, but what those conversations did accomplish for him was almost the same: he made it my problem for being so unkind as to not forgive him. After all, my mother had forgiven him, why couldn’t I? Looking back, I felt increasing pressure to forgive, but I never gave in. I didn’t even really know how.

Here’s why I’m thinking about this now. This Ray Rice and Adrian Peterson conversation, which I’ve been listening to on sports radio, has gotten me to thinking about this stuff. I am listening to these football guys, these pinnacles of macho masculinity, talking about men who abuse women and children, and describing it as unforgivable. Thank god for those men.

Because here’s the thing. It is unforgivable, but until now I hadn’t realized that I was allowed to think so. I’ve been feeling so guilty for so long at not being able to forgive my father, I never realized that I could just be okay with it. But now I do, and I don’t forgive him, and I never will.

After much deliberation, I’ve finally decided to publish this. To be clear, I’m not doing so to hurt my father or my mother. I’m writing it in hopes that by reading this, people will realize that this kind of thing happens everywhere, to all kinds of people, and that it’s always fucked up and wrong. We need to know that, the NFL needs to know that, and policy makers need to know that. We need to create stronger laws around this, that don’t buckle when the women refuse to press charges.

If this happened to you as a kid, it wasn’t your fault, and you don’t have to forgive if can’t or you don’t want to, and even if you don’t forgive them, you will probably still love them. Human beings are really good at conflicting emotions. Focus on not being like that yourself. My proudest accomplishment is that I have not perpetuated the cycle of violence on my own family. And good luck.

The green-eyed/ blue-eyed puzzle/ conundrum

September 17, 2014 54 comments

Today I want to share a puzzle that my friend Aaron Abrams told me a few days ago. I’m sure some of you have heard it before, but it’s confusing me, so I’m asking for your help.

Set-up

Here’s the setup. There’s an island of people, all of whom have either blue eyes or green eyes. By social convention they never discuss eye color, because there’s a tragic rule that states that, if you ever figure out your eye color, you have to leave the island within 24 hours. Oh, and there are no mirrors.

OK, get it? So think of the island as pretty small, maybe 100 people, so you know everyone else’s eye color but not your own.

Here’s what happens next. Some castaway arrives by swimming onto the island, stays for a few days and hangs out with the folks there eating island food and having island parties, and then after building himself a boat he prepares to leave. Not being trained in the social customs of the island, on the day he leaves he says, “hey, it’s good to see some people with green eyes here!”.

Puzzle

So the puzzle is, what happens next?

Here’s what’s obvious. If you are a person who only sees blue eyes, you know by his statement that you must have green eyes. So you have to leave the next day.

But actually he said “some people.” So even if you only see one other person with green eyes, then you have to leave, with that other green-eyed person, after one day.

With me so far?

But hey, what if you see two other people with green eyes? Well, you might think you’re safe, and you’d wait to see them leave together the next day. But what if they don’t leave after one day? That must mean that you also have green eyes. Then all three of you have to leave, after two days. Get it?

Then you work by induction. If you see N other people with green eyes, they should all leave after N-1 days, or else you have green eyes too and all (N+1) of you leave after N days.

Conundrum

OK, so here’s the conundrum. The guy who started this whole mess really didn’t do much. He just stated what was obvious to everyone already on the island, namely that some people had green eyes. I mean, yes, if there were really only 2 people with green eyes, then he clearly added real information, because both those people had thought only 1 person had green eyes.

But just for the fun of it, let’s assume there were 17 people with green eyes. Then they guy really didn’t add information. And yet, 16 days after the guy left, so do all the green-eyed islanders. So really the guy just started a count-down more than anything.

So, is that it? Is that what happened? Or was the original set-up inconsistent? Is it not an equilibrium at all? Or is it an unstable equilibrium?

Saying

In any case, Aaron and his friend Jamie have developed a saying, it’s a green-eyed/ blue-eyed thing, which means it’s an apparently information-free fact which changes everything. I think I’ll use that.

Christian Rudder’s Dataclysm

September 16, 2014 15 comments

Here’s what I’ve spent the last couple of days doing: alternatively reading Christian Rudder’s new book Dataclysm and proofreading a report by AAPOR which discusses the benefits, dangers, and ethics of using big data, which is mostly “found” data originally meant for some other purpose, as a replacement for public surveys, with their carefully constructed data collection processes and informed consent. The AAPOR folk have asked me to provide tangible examples of the dangers of using big data to infer things about public opinion, and I am tempted to simply ask them all to read Dataclysm as exhibit A.

Rudder is a co-founder of OKCupid, an online dating site. His book mainly pertains to how people search for love and sex online, and how they represent themselves in their profiles.

Here’s something that I will mention for context into his data explorations: Rudder likes to crudely provoke, as he displayed when he wrote this recent post explaining how OKCupid experiments on users. He enjoys playing the part of the somewhat creepy detective, peering into what OKCupid users thought was a somewhat private place to prepare themselves for the dating world. It’s the online equivalent of a video camera in a changing booth at a department store, which he defended not-so-subtly on a recent NPR show called On The Media, and which was written up here.

I won’t dwell on that aspect of the story because I think it’s a good and timely conversation, and I’m glad the public is finally waking up to what I’ve known for years is going on. I’m actually happy Rudder is so nonchalant about it because there’s no pretense.

Even so, I’m less happy with his actual data work. Let me tell you why I say that with a few examples.

Who are OKCupid users?

I spent a lot of time with my students this summer saying that a standalone number wouldn’t be interesting, that you have to compare that number to some baseline that people can understand. So if I told you how many black kids have been stopped and frisked this year in NYC, I’d also need to tell you how many black kids live in NYC for you to get an idea of the scope of the issue. It’s a basic fact about data analysis and reporting.

When you’re dealing with populations on dating sites and you want to conclude things about the larger culture, the relevant “baseline comparison” is how well the members of the dating site represent the population as a whole. Rudder doesn’t do this. Instead he just says there are lots of people OKCupid for the first few chapters, and then later on after he’s made a few spectacularly broad statements, on page 104 he compares the users of OKCupid to the wider internet users, but not to the general population.

It’s an inappropriate baseline, made too late. Because I’m not sure about you but I don’t have a keen sense of the population of internet users. I’m pretty sure very young kids and old people are not well represented, but that’s about it. My students would have know to compare a population to the census. It needs to happen.

How do you collect your data?

Let me back up to the very beginning of the book, where Rudder startles us by showing us that the men that women rate “most attractive” are about their age whereas the women that men rate “most attractive” are consistently 20 years old, no matter how old the men are.

Actually, I am projecting. Rudder never actually specifically tells us what the rating is, how it’s exactly worded, and how the profiles are presented to the different groups. And that’s a problem, which he ignores completely until much later in the book when he mentions that how survey questions are worded can have a profound effect on how people respond, but his target is someone else’s survey, not his OKCupid environment.

Words matter, and they matter differently for men and women. So for example, if there were a button for “eye candy,” we might expect women to choose more young men. If my guess is correct, and the term in use is “most attractive”, then for men it might well trigger a sexual concept whereas for women it might trigger a different social construct; indeed I would assume it does.

Since this isn’t a porn site, it’s a dating site, we are not filtering for purely visual appeal; we are looking for relationships. We are thinking beyond what turns us on physically and asking ourselves, who would we want to spend time with? Who would our family like us to be with? Who would make us be attractive to ourselves? Those are different questions and provoke different answers. And they are culturally interesting questions, which Rudder never explores. A lost opportunity.

Next, how does the recommendation engine work? I can well imagine that, once you’ve rated Profile A high, there is an algorithm that finds Profile B such that “people who liked Profile A also liked Profile B”. If so, then there’s yet another reason to worry that such results as Rudder described are produced in part as a result of the feedback loop engendered by the recommendation engine. But he doesn’t explain how his data is collected, how it is prompted, or the exact words that are used.

Here’s a clue that Rudder is confused by his own facile interpretations: men and women both state that they are looking for relationships with people around their own age or slightly younger, and that they end up messaging people slightly younger than they are but not many many years younger. So forty year old men do not message twenty year old women.

Is this sad sexual frustration? Is this, in Rudder’s words, the difference between what they claim they want and what they really want behind closed doors? Not at all. This is more likely the difference between how we live our fantasies and how we actually realistically see our future.

Need to control for population

Here’s another frustrating bit from the book: Rudder talks about how hard it is for older people to get a date but he doesn’t correct for population. And since he never tells us how many OKCupid users are older, nor does he compare his users to the census, I cannot infer this.

Here’s a graph from Rudder’s book showing the age of men who respond to women’s profiles of various ages:

dataclysm

We’re meant to be impressed with Rudder’s line, “for every 100 men interested in that twenty year old, there are only 9 looking for someone thirty years older.” But here’s the thing, maybe there are 20 times as many 20-year-olds as there are 50-year-olds on the site? In which case, yay for the 50-year-old chicks? After all, those histograms look pretty healthy in shape, and they might be differently sized because the population size itself is drastically different for different ages.

Confounding

One of the worst examples of statistical mistakes is his experiment in turning off pictures. Rudder ignores the concept of confounders altogether, which he again miraculously is aware of in the next chapter on race.

To be more precise, Rudder talks about the experiment when OKCupid turned off pictures. Most people went away when this happened but certain people did not:

new-conversations

 

Some of the people who stayed on went on a “blind date.” Those people, which Rudder called the “intrepid few,” had a good time with people no matter how unattractive they were deemed to be based on OKCupid’s system of attractiveness. His conclusion: people are preselecting for attractiveness, which is actually unimportant to them.

But here’s the thing, that’s only true for people who were willing to go on blind dates. What he’s done is select for people who are not superficial about looks, and then collect data that suggests they are not superficial about looks. That doesn’t mean that OKCupid users as a whole are not superficial about looks. The ones that are just got the hell out when the pictures went dark.

Race

This brings me to the most interesting part of the book, where Rudder explores race. Again, it ends up being too blunt by far.

Here’s the thing. Race is a big deal in this country, and racism is a heavy criticism to be firing at people, so you need to be careful, and that’s a good thing, because it’s important. The way Rudder throws it around is careless, and he risks rendering the term meaningless by not having a careful discussion. The frustrating part is that I think he actually has the data to have a very good discussion, but he just doesn’t make the case the way it’s written.

Rudder pulls together stats on how men of all races rate women of all races on an attractiveness scale of 1-5. It shows that non-black men find their own race attractive and non-black men find black women, in general, less attractive. Interesting, especially when you immediately follow that up with similar stats from other U.S. dating sites and – most importantly – with the face that outside the U.S., we do not see this pattern. Unfortunately that crucial fact is buried at the end of the chapter, and instead we get this embarrassing quote right after the opening stats:

 

And an unintentionally hilarious 84 percent of users answered this match question:

Would you consider dating someone who has vocalized a strong negative bias toward a certain race of people?

in the absolute negative (choosing “No” over “Yes” and “It depends”). In light of the previous data, that means 84 percent of people on OKCupid would not consider dating someone on OKCupid.

Here Rudder just completely loses me. Am I “vocalizing” a strong negative bias towards black women if I am a white man who finds white women and asian women hot?

Especially if you consider that, as consumers of social platforms and sites like OKCupid, we are trained to rank all the products we come across to ultimately get better offerings, it is a step too far for the detective on the other side of the camera to turn around and point fingers at us for doing what we’re told. Indeed, this sentence plunges Rudder’s narrative deeply into the creepy and provocative territory, and he never fully returns, nor does he seem to want to. Rudder seems to confuse provocation for thoughtfulness.

This is, again, a shame. A careful conversation about the issues of what we attracted to, what we can imagine doing, and how we might imagine that will look to our wider audience, and how our culture informs those imaginings, are all in play here, and could have been drawn out in a non-accusatory and much more useful way.

Aunt Pythia’s advice

My dear Aunt Pythia propagating loving introspective nerdy girls,

This morning, I am going to imagine sitting in between your lovely kids to enjoy crepes and vent with you. Today’s vent is that I have been highly disturbed by this week’s coverage of the Fields medal (putting aside for the moment the question of whether the Fields medal should exist in the first place). One article I read compared being female in math with being a handicapped competitive athlete.

WTF? This is the news that is being reported and the way people are reacting? What is the most healthy way I can respond to this and still enjoy my Saturday morning crepes?

Love,
SINGing Introspective Nerdy Girl

P.S. I also read the following social media post of a male scientist: “I know I’ll get shit for this, but doesn’t it seem a bit weird that the first woman to win this is butch and wears men’s clothing? Is this because she has a man’s brain, or because she got chosen because she’s man-like?”

I’m not sure it would be a good idea to publicize this, but I would like to ask how I should respond in this situation (feel free to paraphrase the quote if you see fit). I would personally love to publicly shame the male scientist, but I also wanted to make sure I am responding in a way that is helpful and positive to anybody who is reading my message.

In case you are able to see his Facebook posts, the male scientist is “Brian Raney” at USC.

Dear SINGING,

Hmmm… not sure what I can add to this post about the topic, but here goes.

I guess the best way to think about this is as a totally non-mathematical PR thing, which is heavily steeped in weird and fucked up expectations due to historical sexism. As for the USC guy, it would obviously have been infinitely better for him to say something like, “Maryam was awarded the Fields Medal because she did some incredible stellar mathematics.” But there you go, some people miss opportunities to say the right thing. Or maybe he first said the right thing and then he added a bunch of other things after that, who knows. I don’t even care enough to check on his Facebook page. Who cares about what one random guys says?

As for overall butchiness and wearing men’s clothes, lots of female mathematicians do that (including myself many days!), and it’s actually not an uninteresting observation about women in math and other STEM fields, but the phenomenon is certainly not limited to Fields Medal winners.

If you don’t mind me going off into a slight tangent (thanks!), let me also mention that men’s clothes are, generally speaking, great for looking totally unobjectionable, not getting harassed or hit on, and not evoking catcalls (a big deal here in NYC!) compared to short skirts and high heels, and if men could wear them they totally would. Oh wait, they already do.

My point being, there are lots of reasonable reasons to wear men’s clothes besides being a lesbian (although being a lesbian is of course a great reason! And please include suspenders when possible! Fetching!). Being taken seriously as a scholar comes to mind. I defend everyone’s rights to trousers and a boring button-down shirt.

Or, you know, a short skirt and heels if you wanna sex it up and get some attention. Or for the more full-figured gal, a bodycon dress:

Plus-Size-Fall-Winter-2013-Trend-Dresses-02

The key is to get what you want, when you want it.

Keep singing!

Dear Aunt Pythia,

I’m a 24-year-old young woman in New York and I consider myself pretty lucky to absolutely LOVE my job as a “data analyst”. I make great money, my boss trusts me in a sort of crazy way, I can work remotely whenever I want to, and after 6 months, I’ve come to truly believe that my company is an awesome place to work and a pretty great group of people (I guess you could say I’ve been drinking the free chai tea + almond milk). Though I did balk for a second and wonder if I’m just a SQL database monkey, I’m proud to say that if I have to spend 1/7 of my day in SQL but get to spend the rest of it messing around with Python pandas and learning to be a command line ninja, give me a banana and call me Koko.

Now, I won’t have this autonomy forever. This is only my first job, and we’re rapidly expanding, which includes building out an ACTUAL data science department. Without going into too much detail, our platform currently delivers some basic analytics to our customers, and we want to beef up these metrics into something they value us for and, ideally, become dependent on.

We are hiring a director (read: a new boss for me) and we’ve interviewed a ton of people. As you’ve mentioned, a good data scientist is hard to find! I’m pretty outspoken and have spoken up about presenting our clients our with not-quite-as-accurate-as-I-myself-would-like metrics (and I drink chai tea here, not the kool aid). I think I could be a GOOD data scientist someday, but I need the right person to guide me. Most of these candidates are Google Analytics or Tableau jockeys who don’t have any interest in my sweet matplotlib graphs with opacity depending on client billing amount! circumference depending on length of time with us! and so forth.

Last week, I met a candidate that I KNOW will never be topped. She (SHE!!) is also outspoken, knows her shit, cares about data AND ALSO cares about stuff besides data (!) and just is certainly my perfect Yoda. Unfortunately, because the job market is a real thing and a good data scientist is hard to find, I fear that she will not take this job in favor of a better offer elsewhere, financially or otherwise (probably just a bigger company with more data than mine).

Aunt Pythia, HOW do I get her to choose my small company?? This feels to me like the kind of career-changing, perhaps even LIFE changing moment that you have to do EVERYTHING you can to make happen. What would you advise a young woman to do? I have scruples in life, but am not above planting bed bugs at the offices of her competing offer.

Most Enthusiastic Neophyte To Ever Enquire

Dear MENTEE,

You are seriously awesome and you don’t need a Yoda to tell you that, although we’d all love a Yoda.

“PATIENCE YOU MUST HAVE my young padawan”

“PATIENCE YOU MUST HAVE my young padawan”

Here’s the thing. I sense in you the power to be a great data scientist someday, not because your fave boss will or will not take that job, but because you have the obvious urge to do something cool and fun with your life, and because you have integrity, and because you are too smart to trick yourself into thinking what you’re doing is great when it isn’t. Trust in yourself. And if your company doesn’t hire someone awesome, go find yourself another job. Keep learning, keep striving.

Love always,

Aunt Pythia

Dear Aunt Pythia,

I am a junior mathematician just starting to navigate the depth of academia. I am so disillusioned by what I see. I thought being a mathematician was supposed to be this wonderful thing, wherein I exchange ideas with people of similar interests, make friends, and not working but playing.

Instead, I have met so many mean people, who hide what they are doing from me, some who ignore me because they don’t think that I’m good enough, and some who try to intimidate me. When I was a grad student, I even had a student by the same advisor, who never spoke to me once while we were students together, except to try to embarrass me during my talks.

While there are nice people in academia, and I still love being a mathematician, I sometimes become really sad about the mean people in academia. Sometimes, I feel so disillusioned and burned out, then I am too upset to be thinking about math. I feel that I would be so much more productive if only I could deal with these feelings, and I am often frustrated by the fact. Is leaving academia my only solution?

Disillusioned

Dear Disillusioned,

You are right on all accounts! You would be more productive if you could deal with these feelings, and people are mean, and leaving academia would help, although not in the way you think.

Here’s the thing. I left academic math in part because people were so mean. They were really mean to me, and especially because I was a woman, and especially because I was married to a man who was highly respected. It was a situation.

But after leaving academics, mostly what I’ve realized is how most places contain mean people, and academics are really not all that good at being mean. No offense to mean mathematicians! But really they are like, small-fry mean. If you want to see hugely assholic behavior, work in finance for a few years.

So I’m wondering if this might help – and it might not, of course – but if you can, engage in the following thought experiment: you have left academics, and you go into some other field, and people are mean there too, except for a few nice people with whom you can bitch about the meanies. Then you leave that job and go in search of another job, where maybe there are fewer assholes but also you don’t get paid as well and there are other problems that come up because of that, or because the job stability is rough, or etc. etc.

Then after that long thought experiment, you might realize that as long as there are resources to be fought over, there will be fights, and the question is how to ignore all the stupid bickering and get some math done, because after all math is beautiful and awesome and it’s not math’s fault that all these people are mean.

Good luck!

Dear Aunt Pythia,

My colleagues and I at the Militant Grammarians of Massachusetts would like to know why the word “data” is plural while the phrase “big data” is singular.

Your singular,
Big Datum

Dear Big Datum,

OK here’s where I am on this issue. It’s always singular. Always. Look at the data! All the data points to the same conclusion! There might be several data points that offer alternative preferences, but those are outliers. Every time I hear someone say something incredibly awkward like, “Are your organization’s data as clear as they can be?” I just wanna retch. Don’t do it. You just sound like a grammar nazi, and nobody likes those people.

You asked!

What’s next for mathbabe?

September 12, 2014 11 comments

The Columbia J-School program that I have been directing, The Lede Program in Data Journalism, has wound down this past week and in four days my 6-month contract with Columbia will end. I’ve had a fantastic time and I am super proud of what we accomplished this past summer. The students from the program are awesome and many of them are now my friends. About half of them are still engaged in classes and will continue to work this semester with Jonathan Soma, who absolutely rocks, and of course my fabulous colleague Theresa Bradley, who will step in as Director now that I’m leaving.

So, what’s next? I am happy to say that as of today (or at least as of next Monday when my kids are really in school full-time) I’m writing my book Weapons of Math Destruction on a full-time basis. This comes as a huge relief, since the internal pressure I have to finish this book is reminiscent of how I felt when I needed to write my thesis: enormous, but maybe even worse than then since the timeliness of the book could not be overstated, and I want to get this book out before the moment passes.

In the meantime I have some cool talks I’m planning to go to (like this one I went to already!) and some I’m planning to give. So for example, I’m giving a keynote at The Yale Day of Data later this month, which is going to be fun and interesting.

My Yale talk is basically a meditation on what can be achieved by academic data science institutions, what presents cultural and technical obstacles to collaboration, and why we need to do it anyway. It’s no less than a plea for Yale to create a data science institute with a broad definition of data science – so including scholars from law and from journalism as well as the fields you think of already when you think of data science – and a broad mandate to have urgent conversations across disciplines about the “big data revolution.” That conversation has already begun at the Information Society Project at Yale Law School, which makes me optimistic.

I also plan to continue my weekly Slate Money podcasts with Felix Salmon and Jordan Weissmann. Today we’re discussing the economic implications of Scottish independence, Felix’s lifetime earnings calculator, and the Fed’s new liquidity rules and how they affect municipalities, which my friend Marc Joffe guest blogged about yesterday.

Guest post: New Federal Banking Regulations Undermine Obama Infrastructure Stance

September 11, 2014 11 comments

This is a guest post by Marc Joffe, a former Senior Director at Moody’s Analytics, who founded Public Sector Credit Solutions in 2011 to educate the public about the risk – or lack of risk – in government securities. Marc published an open source government bond rating tool in 2012 and launched a transparent credit scoring platform for California cities in 2013. Currently, Marc blogs for Bitvore, a company which sifts the internet to provide market intelligence to municipal bond investors.

Obama administration officials frequently talk about the need to improve the nation’s infrastructure. Yet new regulations published by the Federal Reserve, FDIC and OCC run counter to this policy by limiting the market for municipal bonds.

On Wednesday, bank regulators published a new rule requiring large banks to hold a minimum level of high quality liquid assets (HQLAs). This requirement is intended to protect banks during a financial crisis, and thus reduce the risk of a bank failure or government bailout. Just about everyone would agree that that’s a good thing.

The problem is that regulators allow banks to use foreign government securities, corporate bonds and even stocks as HQLAs, but not US municipal bonds. Unless this changes, banks will have to unload their municipal holdings and won’t be able to purchase new state and local government bonds when they’re issued. The new regulation will thereby reduce the demand for bonds needed to finance roads, bridges, airports, schools and other infrastructure projects. Less demand for these bonds will mean higher interest rates.

Municipal bond issuance is already depressed. According to data from SIFMA, total municipal bonds outstanding are lower now than in 2009 – and this is in nominal dollar terms. Scary headlines about Detroit and Puerto Rico, rating agency downgrades and negative pronouncements from market analysts have scared off many investors. Now with banks exiting the market, the premium that local governments have to pay relative to Treasury bonds will likely increase.

If the new rule had limited HQLA’s to just Treasuries, I could have understood it. But since the regulators are letting banks hold assets that are as risky as or even riskier than municipal bonds, I am missing the logic. Consider the following:

  • No state has defaulted on a general obligation bond since 1933. Defaults on bonds issued by cities are also extremely rare – affecting about one in one thousand bonds per year. Other classes of municipal bonds have higher default rates, but not radically different from those of corporate bonds.
  • Bonds issued by foreign governments can and do default. For example, private investors took a 70% haircut when Greek debt was restructured in 2012.
  • Regulators explained their decision to exclude municipal bonds because of thin trading volumes, but this is also the case with corporate bonds. On Tuesday, FINRA reported a total of only 6446 daily corporate bond trades across a universe of perhaps 300,000 issues. So, in other words, the average corporate bond trades less than once per day. Not very liquid.
  • Stocks are more liquid, but can lose value very rapidly during a crisis as we saw in 1929, 1987 and again in 2008-2009. Trading in individual stocks can also be halted.

Perhaps the most ironic result of the regulation involves municipal bond insurance. Under the new rules, a bank can purchase bonds or stock issued by Assured Guaranty or MBIA – two major municipal bond insurers – but they can’t buy state and local government bonds insured by those companies. Since these insurance companies would have to pay interest and principal on defaulted municipal securities before they pay interest and dividends to their own investors, their securities are clearly more risky than the insured municipal bonds.

Regulators have expressed a willingness to tweak the new HQLA regulations now that they are in place. I hope this is one area they will reconsider. Mandating that banks hold safe securities is a good thing; now we need a more data-driven definition of just what safe means. By including municipal securities in HQLA, bank regulators can also get on the same page as the rest of the Obama administration.

Wife beating education for sports fan and everyone else

Do you know what I am doing this morning? I’m glued to ESPN talk radio, which is 98.7FM in the NYC area, although it is a national station and can be streamed online as well.

Here’s a statement you might be surprised to hear from me. In the past decade, sports talk radio has become the best, rawest, and most honest source of information about how our culture condones and ignores violence against women, not to mention issues of race and homophobia. True fact. You are not going to hear this stuff from politicians or academics.

Right now I’m listening to the Mike & Mike program, which has guest Jemele Hill, who is killing it. I’m a huge fan of hers.

The specific trigger for the conversation today is the fact that NFL football player Ray Rice has been indefinitely suspended from playing now that a video has emerged of him beating his wife in the elevator. Previously we had only gotten to seen the video of her slumped body after he came out of the elevator with her. The police didn’t do much about it, and then the NFL responded with a paltry 2-game suspension, after which there was such a backlash (partly through sports radio!) that the commissioner promised to enact a stronger policy.

Questions being addressed right now as I type:

  1. Why didn’t the police give Rice a bigger penalty for beating his wife unconscious?
  2. Why didn’t the NFL ask for that video before now? Or did they, and now they’re lying?
  3. What does it say about the NFL that they had the wife, Janay Rice, apologize for her role in the incident?
  4. What did people think it would look like when a professional football player knocks out a woman?
  5. Did people really think she did something to deserve it, and now they are shocked to see that she didn’t?
