Ranking Economics Journals

In New Approaches to Ranking Economics Journals (or here) the authors rank journals based on citations from a larger sample of journals than has been used in the past, they distinguish overall journal impact from the impact per article and they break down impact into impact within economics, impact within all of social science, impact within policy and impact outside of economics. 

When impact is measured by citations from journals within economics, journal impact and impact per article are pretty much what you would expect with the AER, QJE, JPE and Econometrica all scoring highly.

Expanding the citation list to all social science, however, has some big effects especially on impact per article.  Most notably, the Journal of Law and Economics has the highest overall impact ranking per article.

Frankly, I was thrilled to see the JLE rank so highly since I have published a number of papers in that journal.  Come to think of it, the latter obviously explains the former!  Note, by the way, that the citation list does not include law journals so if anything the JLEs impact may be under-weighted.

Kudos must also go to Robert Barro, Ed Glaeser and Lawrence Katz, the editors of the Quarterly Journal of Economics, which is the only journal to rank in the top 5 categories no matter how you break down the data.

Trade and the Moral Community

Much of the recent trade debate between Rodrik, Mankiw, Tyler and others (see Tyler’s excellent post for links) is primarily not about positive economics but about the relevant moral community. Rodrik, for example, hasn’t argued that trade does not increase aggregate wealth he has argued that trade is not guaranteed to increase national wealth – something quite different.  I consider three moral communities and the case for trade.

Peter wishes to trade with Jose.  The individualist says the relevant moral community is Peter and Jose and presumptively no one else.  Trade, the right of association, is a human right and on issues of rights the moral community is the individual.  When Jose offers Peter a better deal than Joe it’s wrong – a moral outrage – for Joe to prevent Jose at gun point from trading with Peter.

The more common view expressed implicitly by Dani Rodrik, but by many others as well, is the nationalist view, the moral community is Peter and Joe.  Joe gets a vote on Peter’s trades.  Peter should be allowed to trade only if both Peter and Joe benefit, otherwise too bad.  Jose counts for less.

A third view, that of the liberal internationalist, says that Peter, Jose and Joe count equally and are together the moral community.

Now how does the positive economics apply to these three cases?  Peter and Jose presumptively are better off from trade otherwise they wouldn’t trade so the individualist economist (the economist who takes Peter and Jose as the relevant moral community) will support free trade.  The liberal internationalist will also support free trade because there is a strong argument from positive economics that trade increases total wealth (comparative advantage, specialization, competition etc.).

In between, we have the nationalist economist for whom it depends.  The case for trade for the nationalist economist is pretty good – after all the individuals involved benefit and the world benefits – so the case is reasonably strong that Peter and Joe taken together will also benefit especially if we consider many trade pacts on some of which Joe benefits directly.  Nevertheless, Rodrik is correct that when you exclude Jose it is possible to come up with examples where Joe’s losses exceed Peter’s gains.

I would argue, however, that economists are too quick to take the nation as the relevant moral community.  It is quite possible, for example, for Peter to benefit from trade but for Peter’s city to be harmed, for Peter’s state to benefit but for his region to be harmed, for his country to benefit but for his continent to be harmed.  Why should we cut the cake in one way, excluding some from the moral community, but not in another?  Indeed, geography is not the only way we can define the moral community.  Why not ask whether English speakers benefit from free trade or Christians or left handed people?  Each of these is just as valid as asking whether the collection of people called the nation benefit from free trade.

I understand individual rights and I understand counting everyone equally but I see less value in counting some in and some out based on arbitrary characteristics like which side of the border the actors fall on.

Protection Racket

Who is protecting borrowers from "predatory lending"?  The trial lawyers!  Feel better?  I didn’t think so.  Ted Frank, writing in the Wall Street Journal has the story.  Yours truly makes an appearance.

The trial lawyers’ entrepreneurial solution is to go
after the deep pocket. And so we have lawsuits alleging that the
investment banks providing financing to the mortgage banks are "aiding
and abetting" the alleged fraud through securitization.

What would be the upshot? If an investment bank is
potentially liable for every conversation and every phone call involved
in the underlying mortgages, the costs of due diligence becomes
prohibitive, far outstripping the fees it can bring in for packaging
the loans…The securitization
simply will not take place….

To make matters worse, the House Financial Services Committee held
hearings last week on writing this judicial mistake — and more — into
federal statutory law. Committee Chair Barney Frank (D., Mass.), wants
to hold not only the packagers of mortgages liable but also the purchasers in
the secondary market. "Anybody, including the original borrower, can
make a claim, and the liability would go up the chain," Mr. Frank told
the press….

It is not speculation to say that the results will be disastrous if
such a bill becomes law….the 2002 Georgia Fair Lending Act created unlimited liability
to purchasers of mortgages for any legal violations by the loan
originator…all three of the major credit ratings agencies (S&P, Moody’s, and
Fitch) announced they could not rate any securitization containing any
loans subject to Georgia law for fear that the entire security would be
tainted by unquantifiable liability. Liquidity for the state’s mortgage
market disappeared and the Georgia legislature quickly repealed the
worst parts of the law to restore access to credit.

Let the Taxpayers Take Care of It

A new GAO Report tells us that unlike private insurers government insurers are not planning for the risks of climate change.

Major private and federal insurers are both exposed to the effects of climate change over coming decades, but are responding differently. Many large private insurers are incorporating climate change into their annual risk management practices, and some are addressing it strategically by assessing its potential long-term industry-wide impacts. The two major federal insurance programs, however, have done little to develop comparable information.

This would seem to put some of my free market friends who continue to believe that global warming is a leftist hoax in something of a bind.  Is climate change real or are government regulators wise and farsighted?

Harry Potter and the Mystery of Inequality

J.K. Rowling is the first author in the history of the world to earn a billion dollars.  I do not disparage Rowling when I say that talent is not the explanation for her monetary success.  Homer, Shakespeare and Tolkien all earned much less.  Why?  Consider Homer, he told great stories but he could earn no more in a night than say 50 people might pay for an evening’s entertainment.  Shakespeare did a little better.  The Globe theater could hold 3000 and unlike Homer, Shakespeare didn’t have to be at the theater to earn.  Shakespeare’s words were leveraged.

Tolkien’s words were leveraged further. By selling books Tolkien could sell to hundreds of thousands, even millions of buyers in a year – more than have ever seen a Shakespeare play in 400 years.  And books were cheaper to produce than actors which meant that Tolkien could earn a greater share of the revenues than did Shakespeare (Shakespeare incidentally also owned shares in the Globe.)

Rowling has the leverage of the book but also the movie, the video game, and the toy.  And globalization, both economic and cultural, means that Rowling’s words, images, and products are translated, transmitted and transported everywhere – this is the real magic of Ha-li Bo-te.

Rowling’s success brings with it inequality.  Time is limited and people want to read the same books that their friends are reading so book publishing has a winner-take all component.  Thus, greater leverage brings greater inequality.  The average writer’s income hasn’t gone up much in the past thirty years but today, for the first time ever, a handful of writers can be multi-millionaires and even billionaires.  The top pulls away from the median.   
The same forces that have generated greater inequality in writing – the leveraging of intellect, the declining importance of physical labor in the production of value, cultural and economic globalization – are at work throughout the economy.  Thus, if you really want to understand inequality today you must first understand Harry Potter.

Reviewing Landsburg’s Errors

In the Armchair Economist, Steven Landsburg argues that the people who read his book are likely to find that it wasn’t as good as they expected.  The logic is impeccable – people who over-estimate the value of the Armchair Economist are more likely to buy it and thus discover their over-estimation (sadly, under-estimators never learn of their mistake).  Nevertheless, despite the logic, I and many others discovered that Landsburg was wrong.  The Armchair Economist and every Landsburg book exceed expectations. 

Landsburg is back with More S-ex is Safer S-ex, and another error.  This time Landsburg suggests that writing his book was socially destructive.  Again, the logic is impeccable – a good book creates a lot less value than its price because to a large extent it displaces the second best book which was almost as good.  Authors however are paid based on price and not on social value and thus write too many books.  And yet, I must again disagree for Landsburg’s new book is a treasure.  There is something to learn on almost every page.

Here’s one idea I learned.  In the debate over the economics of global warming the correct discount rate to apply to future generations is a key variable with those arguing that we should do something now, implicitly (and explicitly) arguing for a low discount rate.  But if we count future generations highly we ought also to be in favor of reforming social security.  Investing social security in the stock market "royally screws" current retirees but increases the savings rate which will be benefit future generations.  Thus, a low discount rate ought to weigh in favor of doing something about global warming and investing social security funds in the stock market.  Not many people come out consistent on these grounds (I think Brad DeLong is one of the few.)  I know, I don’t but Landsburg has got me thinking.

The Patriarchy at Work

Many studies have shown that women are
under-represented in tenured ranks in the sciences. We evaluate
whether gender differences in the likelihood of obtaining a
tenure track job, promotion to tenure, and promotion to full
professor explain these facts using the 1973-2001 Survey of
Doctorate Recipients. We find that women are less likely to take
tenure track positions in science, but the gender gap is entirely
explained by fertility decisions. We find that in science
overall, there is no gender difference in promotion to tenure or
full professor after controlling for demographic, family,
employer and productivity covariates and that in many cases,
there is no gender difference in promotion to tenure or full
professor even without controlling for covariates. However,
family characteristics have different impacts on women’s and
men’s promotion probabilities. Single women do better at each
stage than single men, although this might be due to selection.
Children make it less likely that women in science will advance
up the academic job ladder beyond their early post-doctorate
years, while both marriage and children increase men’s likelihood
of advancing.

Addendum: Tyler linked to an earlier version of this paper but if I forgot then probably so did you so here it is again.

Public Opinion and War

Political scientist Scott Althaus was here last week and had a lot of interesting things to say about war and public opinion.  Here is one tidbit.  The public’s opinion of past wars improves as a new war approaches.  Thus, after Vietnam most people thought the war was a mistake and this held true for decades until the beginning of the Iraq war when the opinion of war in Vietnam suddenly improved!  Even more dramatically, a majority of people thought that World War I was a mistake until World War II approached when the percentage thinking it was a good war doubled.  This is especially perverse in that any rational response has got to see WWI as a bigger mistake the more probable is WWII. 

Althaus also shows, in Priming Patriots, that the intensity of new coverage typically increases support for war – regardless of whether the coverage is negative or positive.  Until negative news becomes overwhelming and long-lasting, more coverage simply rallies the martial spirit, encourages solidarity and solidifies support for the war.  This explains a lot.

What checks on democracy are required to deal with the irrationality of public opinion about war? 

The Rise, Fall, and Rise Again of Privateers

In August 1812, the Hopewell, a 346-ton ship laden with sugar, molasses, cotton, coffee, and cocoa, set sail from the Dutch colony of Surinam. Her captain was pleased because he reckoned that in London the cargo would sell for £40,000–the equivalent of at least several million dollars in today’s economy. The Hopewell carried fourteen guns and a crew of twenty-five, and for protection she sailed in a squadron of five other vessels. It was difficult, however, to keep a squadron together in the vast expanse of the Atlantic Ocean, and on August 13 the Hopewell became separated from her sisters.

    Two days later her crew spotted another ship, armed and approaching rapidly…

That’s the opening of my latest paper, The Rise, Fall, and Rise Again of Privateers.
