Credit Rationing

Utah payday lenders began refusing Monday to make loans to members of
the military rather than give them much lower rates mandated by a new
federal law.

That new law, which took effect Monday, caps the annual interest on
payday, car title or tax refund anticipation loans at 36 percent
annually for members of the military and their families….

"At 36 percent annual percent rate, the total fees we could charge are
$1.38 per $100 for a two-week loan. That is less than 10 cents a day,"
Walker said.

"Payroll advance lenders could not even meet employee payroll at that
rate, let alone cover other fixed expenses and make a profit," he said.

I’m surprised that it is constitutional for the government to require firms to lower prices for certain groups.  I’m not surprised that the law has unintended consequences – but perhaps the consequences were not unintended.

"The protection the regulation offers is not a wall preventing a
service member from getting assistance, rather it is more like a
flashing sign pointing out danger and directing the borrower to a safer
way of satisfying immediate financial need," said Leslye A. Arsht,
deputy undersecretary of defense for military community and family
policy.

He said financial help for members of the military is available through
a member’s chain of command, legal assistance office or military aid
society.

So the military doesn’t pay you enough to pay your bills and then they reduce your borrowing options while suggesting that you can borrow more from them.  Hmmm… reminds me of a company town.

More on the story here and a hat tip to Overlawyered and Bob M.

Who will win the Nobel Prize in economics this year?

Greg Mankiw asks and receives many answers

One guess is William Nordhaus, for his concept of "green accounting."  An environmental prize is overdue but perhaps Nordhaus is too skeptical about stringent anti-global warming measures to get the appropriate reception in Stockholm.

Another option is Eugene Fama, both for testing CAPM for securities prices and for figuring out what is wrong with it.  You can imagine pairing his prize with either Richard Thaler (behavioral finance) or Kenneth French (Fama’s co-author on many important papers).

Or how about Oliver Williamson and/or Jean Tirole for principal-agent theory as applied to the business firm?

I would offer the prize jointly to Anne Krueger, Jagdish Bhagwati, and Gordon Tullock for their work on rent-seeking, but that is not my prediction.  Readers, what do you think?

Oomph v. Statistical Significance

For those after the full debate, see:

McCloskey has been making this point for some time, and a longer list of papers is available here, including several shorter (yet unsurprisingly persuasive) pieces.

Can computer failure cause a bank run?

Over the past few days, something strange happened to me: My debit card simply stopped working. This caused a sticky situation when I was traveling, and I was lucky that my cabbie took $27 plus a 20 euro note for a $37 cab fare.

My problem turned out to be a widespread problem with my bank’s computer system.  This is a bank with a large internet presence and no physical branches in my state, so many customers really were stuck with a cash-free few days (which is less fun than being cash-flush, I assure you.)

So what will I do when the computer problems are solved?  I plan on withdrawing $500 so that I’m not caught short if these problems recur next week.  More generally, if account-holders fear that computer glitches tend to repeat themselves (computer failure is autocorrelated), then we will all be lining up (electronically) to make withdrawals.  Some may even be so dismayed by recent events as to close their accounts.

Why haven’t I named the Bank?  Because if enough people are aware of this situation, then these correlated withdrawals become a Bank Run.  The possibility of online withdrawals certainly sped up the the recent run on the UK-based Northern Rock bank, and website problems raised anxiety.  But my (new) fear is entirely a computer-glitch precipitated bank run.

I must admit, I’m not aware of any bank runs – to date – caused by computer problems.  But here’s a forecast: IT problems will cause a bank run within a decade.  Fortunately these sorts of runs are unlikely to cause widespread financial instability.  My advice? If you work in IT at a bank: Demand a raise – your bank’s future depends on you.

Visiting Dartmouth

I’m spending a couple of days at Dartmouth right now, visiting friends and colleagues at the economics department.  I’ll be trying to sneak in posts between meetings.  But one thing I can’t help but notice: this department is a persistent overperformer.  Click on just about anyone’s homepage, and you’ll find creative folks doing first-rate (usually empirical) research on important questions.  And worse: They are all so damn friendly.

Dartmouth have also just hired one of my favorite economists and coauthors, Eric Zitzewitz.  Look for creativity and colleagiality to continue.

Why the Left should learn to love liberalism

Labour-market flexibility, deregulation of the service industry,
pension reforms and greater competition in university funding is not
anti-equality. Such reforms shift financing from taxpayers to the users
themselves and, as such, tend to eliminate rents. They tend to increase
productivity by basing rewards on merit rather than on being an
insider. They tend to open up opportunities for younger workers who are
not yet well-connected. Pursuing pro-market reforms does not imply
facing a trade-off between efficiency and social justice. In this
sense, pro-market policies are “left wing”, if that means reducing the
economic privileges enjoyed by “insiders”.

…If the European left wants to be able to say honestly that it fights
for the neediest members of our society, it must adopt as its battle
cry the pursuit of competition, reforms and a system based on
meritocracy.

Amen.  This is from an excellent op-ed by Alberto Alesina and Francesco Giavazzi writing in Vox.  My only complaint is that they write as if this is new.  In fact, liberalism, meaning classical liberalism, has never been conservative.  It began as a movement of the left against feudalistic, conservative insiders and it remains so today.

Thinking about Sports and Economics

I spent last Saturday at a very interesting conference on Sports Statistics, run by the Sports Stats section of the American Statistical Association.  It was a fun day, involving academics, sports journalists, and those Moneyball-inspired quants working for various sports teams.

But at some point I asked myself: Why do economists work on sports?

  1. Sports provide unique opportunities to test economic theories.  Cribbing from a New York Times article, this is the Thaler defense:

    “‘My justification for doing this is that it’s the one really
    high-stakes activity where you get to watch all of the decisions,”
    Thaler said. ”If Bill Gates invited me to watch all of his decisions,
    I’d talk more about that.”

  2. Sports shapes broader national debates.  Sports is a microcosm of our broader society and our national narrative on the important issues, from drugs, to race, to cheating, to sexual harrassment often play out on our sports pages.  In honor of a particularly compelling example, let’s
    call this the Jackie Robinson defense.
  3. Professional sports are an important part of the economy.  I call this the Dog defense, not as a dyslexo-religious statement, but simply because dogs raise an important question: aren’t pets a bigger part of the economy than professional athletics?  If so, why are there so many papers on professional sports and so few on the economics of dogs?
  4. Sports participation is an important activity.  It seems important to learn whether sports make us happier, healthier or more productive.  For instance, it is important to learn, say, what the broader effects of Title IX were.  Under this view, research on sports is part of the human capital agenda, leading me to call this the Gary Becker defense.
  5. Sports provides a useful teaching metaphor.  Many of those teaching Sabermetrics-inspired courses argue that sports provides a useful vehicle for teaching something far more important – basic quantitative reasoning.  When I teach my class on behavioral economics, I do so by analyzing anomalies in sports betting markets.
  6. Doing research on sports is fun.  It was no mistake that the conference I attended was on a Saturday.  Many of the academics in attendance were giving up leisure, not more important work. But for some, sports provides a chance to mix work with leisure; of course, if non of the above arguments holds, then it is just a chance to mix leisure with leisure.

Let me now translate this into advice, because I often hear from students wanting to write a thesis on sports.   My first response is always: Don’t.  Too often, we find our sporting heroes more interesting than other people do.  (Yes, I have been guilty of breaking this rule.)

But if you must work on sports, make sure you have a defense to this charge. I find the Thaler and Becker defenses most compelling, because they speak to the broader economic issues or yield policy implications.  The Jackie Robinson defense is also important, but not applicable often enough.  The Dog defense is often raised, but rarely compelling; neither pets, nor professional sports, are really a big part of the economy (estimates to the contrary usually turn out to be more applicable to the Becker defense).

George Will on Austan Goolsbee

It is rare that an Op-Ed is written praising an economist.  It makes many good points but there is one unjustified slap:

Goolsbee no doubt has lots of dubious ideas — he is, after all, a Democrat — about how government can creatively fiddle with the market’s allocation of wealth and opportunity.

Does the use of "no doubt" mean Will actually knows this?  But the next sentence comes and the piece closes on a different note altogether:

…he seems to be the sort of person — amiable, empirical and reasonable — you would want at the elbow of a Democratic president, if such there must be.

Markets in everything

There’s a hot market for demilitarized ICBM silos. There are three of
them on offer at eBay right now, with the asking price of $500,000 per
silo, which includes underground and above ground support facilities.
Hundreds of ICBM silos have been sold off in the last twenty years, as
new missile forces were reduced with the end of the Cold War, and the
enactment of arms reduction treaties.  Most of these are located in
remote areas.  For example, the three silo complex being offered on eBay
sits on 57 acres in central Washington State.

Here is further information

And while we are on the markets in everything topic, here is what Indians will do for you (if you pay them).

And here is a New Zealand market: lingerie for men (TC: clicking on this site is a mistake, please don’t do it, if only to avoid the music), who said small population and fixed costs limit product diversity (though they do ship by mail, how much of their business is Kiwi)? 

Thanks to several loyal MR readers for the pointers, at least one of them may wish to remain anonymous.

In the shower with Robert Frank

I tend to listen to NPR while showering, and really enjoyed this morning’s interview with Robert Frank.  The interview draws heavily from his book, The Economic Naturalist – previous blogged about by Tyler, here and here.

Robert Frank’s observations on economics teaching will fundamentally change what I do in the classroom.  What he has to say is important.  Read it.  Here.

Yes, this was previously covered on MR (here and here).  But I am intrigued by Frank’s ambition in arguing that we need to emphasize the "deep" concepts of economics in a way that transforms how our students see the world.  We econ profs probably fail, and it is hard to see how to do better.  But it is worth doing.

Perhaps blogs like Marginal Revolution help one better see the world through an economists lens.  But most econ profs teach in the classroom, not the blogosphere, and so I want to ask: How can we do a better job teaching what is important, true and beautiful in economics? Comments open.  But a request: Please only comment if you have taken the time to read the Frank piece (this one).

How to sound smart around the water cooler

The baseball playoffs begin today. (Go Red Sox!)  But if you haven’t been following the 162-game season, you may risk sounding foolish around the water cooler.

Here’s how to sound like an expert: Research tells us that prediction markets yield accurate forecasts.  Indeed, a prediction market forecast is likely smarter than any expert.  Simply point your browser to your favorite prediction market, and make the following observations confidently around the water cooler:

  1. Note that the American League looks much stronger than the National League.  (HT: Mike Giberson at Midas Oracle.)
  2. Sigh, while you say that "Once again the American League race looks like being the Red Sox or the Yankees."
  3. State emphatically that "the National League is anyone’s race.  Heck, even the come-from-behind Phillies are a chance."  (Say this as though you didn’t already know they were the betting favorites)

That’s it.  You are now an expert.  (How else do you think an Aussie can keep up a conversation about U.S. sports? I’ve been faking it for years… but shhh, don’t tell David Stern.)

The Real Significance of Changes in the Gender Happiness Gap

A qualifier: None of these comparisons are entirely satisfactory.  For instance, if you believe that there is very little variation in happiness across people, time, or states of the economy, then you would interpret the above comparisons as suggesting that the change in the female happiness gap is big, only when compared with small things.

Another qualifier: We only document changes in the measured gender happiness gap.

Any other ideas on how to describe the "oomph" (or economic significance) of changes in qualitative variables like happiness?

UPDATE 1: Steve Levitt chimes in.

UPDATE 2: Jezebel adds some perspective.

How free market are economists?

…a group of economists at George Mason University, and other
prominent researchers, say this notion of a free-market mainstream is
oversimplified at best and inaccurate at worst.

“There’s really not any data, and there’s a caricature, that
economists are extremely free market,” said Tyler Cowen, a professor of
economics at George Mason who is popular in free-market and libertarian
circles. “I think the differences are overdrawn.”

My colleague Daniel Klein, the central focus of this article, has shown that economists’ views are quite mainstream and often closely aligned with the Democratic Party:

And Klein has numbers to back up his claims. Some of those numbers come in the form of party donations, similar to studies (some of which have also been done by Klein at George Mason) purporting to show political bias among professors in academe: For example, one Econ Journal Watch study
found a 5.1 to 1 ratio between contributors to the Democratic versus
Republican party among a sample of 2,000 members of the AEA. Klein
found similar lopsidedness in the authors and editors of journals
(including the Journal of Economic Literature) and even within the groups of people listed in authors’ acknowledgments in journal articles.

Read the whole thing, which also includes a debunking of the notion of heterodox economics.  Often the real dissent in economics comes from the free market side; left-wing heterodoxy is more aligned with the mainstream than it cares to admit.  The piece closes with some me:

“So, everyone in a debate always wants to call the other side
ideologues, essentially, and the critics of economics are doing that
here,” Cowen explained. “They like to think they’re on the outside,
there’s something new, they’re warring against some powerful authority.”

About theories that run counter to the neoclassical model, he said, “It’s a view that’s been with us for centuries.”

Canada v. U.S. on Health Care

Jason Shafrin, the Healthcare Economist, has a good review of the O’Neil and O’Neil NBER working paper, Health Status, Health Care and Inequality: Canada vs. the U.S.  (This paper was also mentioned by Tyler recently).

American are less healthy than Canadians. What this paper finds, however, is
that this is mainly due to the fact that the U.S. has a higher incidence of
disease. It turns out that Americans may have slightly higher access to
treatment than Canadians.

Read the full review.  Of course, the Canadian system is cheaper but very few people are willing to lobby for less health care.

Regression-heads

Probably influenced by Tyler’s post on Radiohead, my last post ended by providing computer code for "regression-heads" to replicate some numbers.  But what is the right term for those I just called (affectionately) regression-heads?

  1. Ian Ayres would call you a Super Cruncher
  2. Steve Levitt would suggest you are a Freakonomist
  3. If this were the Society for American Baseball Research you would be a Sabermetrician
  4. Our friends in finance would call you a quant.

Perhaps readers of this blog are Marginal Revolters?  Other ideas?

(Yes, I’ve heard Econometrician.)
