Neglect of the Important Issues, Is the Opportunity Cost of Pursuing the Cutely Clever

 

The Wall Street Journal summarizes an April 2, 2007 article by Noam Scheiber in The New Republic:

 

A new generation of economists has become so addicted to cleverness that dull but genuinely useful research is under threat.

"Freakonomics," the 2005 best seller that sought to explain the mysteries of everyday life through economics, is only partly to blame, writes Noam Scheiber. The deeper roots lie in a 1980s crisis of faith over economists’ ability to reliably crunch numbers. Influential economist H. Gregg Lewis kicked it off by demonstrating that a host of broad, worthwhile empirical surveys of unions’ impact on wages came to opposite conclusions, mostly thanks to the differing original assumptions by the studies’ authors.

As a result, some economists retrenched, opting to focus on finding "solid answers to modest questions."

Obama Advised By Economists Cutler, Liebman, and Goolsbee

 

  Source of graphic:  online version of the WSJ article cited below.

 

In a previous entry, I expressed guarded optimism in response to an article that identified Austan Goolsbee as an advisor to Obama.  The article excerpted below, casts Goolsbee in a less central role, thus giving reason to guard the optimism even more.

 

While Mr. Obama’s economic platform is still in its formative stages, interviews with his aides and a review of his congressional record and speeches suggest that Obamanomics may place him somewhat to the left of New York Sen. Hillary Rodham Clinton, but to the right of former North Carolina Sen. John Edwards, another rival for the 2008 nomination. Mrs. Clinton seems to be cultivating the centrist mantle her husband won during his presidency, while Mr. Edwards is courting the party’s labor and grassroots activist base.

. . .

As Mr. Obama prepares for his first series of domestic-policy speeches in the coming weeks, he appears to be still shopping for a place on the political spectrum.

One top economic adviser is Jeffrey Liebman, a Harvard economist and former adviser to President Clinton who is focused heavily on the earned income tax credit and its role in moving people from welfare to work.

The candidate is also consulting with University of Chicago economics professor Austan Goolsbee, a taxation expert and centrist Democrat who has advised Mr. Obama since his 2004 Senate campaign.

David Cutler, a Harvard economist specializing in health policy who served in the Clinton administration, is also among Mr. Obama’s advisers.

“Not that Everyone Has Been Intimidated”

 

It is common to ridicule economists–sometimes with some good reason.  But the 50 brave economists in Iran who refused to be intimidated, have made us proud.

 

(p. 1)  Iran is in the throes of one of its most ferocious crackdowns on dissent in years, with the government focusing on labor leaders, universities, the press, women’s rights advocates, a former nuclear negotiator and Iranian-Americans, three of whom have been in prison for more than six weeks.

The shift is occurring against the backdrop of an economy so stressed that although Iran is the world’s second-largest oil exporter, it is on the verge of rationing gasoline. At the same time, the nuclear standoff with the West threatens to bring new sanctions.

The hard-line administration of President Mahmoud Ahmadinejad, analysts say, faces rising pressure for failing to deliver on promises of greater prosperity from soaring oil revenue. It has been using American support for a change in government as well as a possible military attack as a pretext to hound his opposition and its sympathizers.

. . .

(p. 9)  Not that everyone has been intimidated. More than 50 leading economists published a harshly worded, open letter to the president saying his policies were bringing economic ruin. High unemployment persists, there has been little foreign investment and inflation is galloping, with gasoline alone jumping 25 percent this spring.

Gasoline rationing is expected within a month, with consumers so anxious about it, reported the Web site Ruz, financed by the Dutch government, that skirmishes broke out in long lines at some pumps on June 17.

Obama Advised by Market-Oriented Chicago Economist Goolsbee

 

(p. C1)  The Democrats, besides talking about a broader range of subjects, also have the freshest face among the top campaign advisers — Barack Obama’s lead economist, Austan Goolsbee, a 37-year-old star professor at the University of Chicago (who writes a monthly column for The New York Times). The two men met when Mr. Obama was teaching at the law school there, and they both seem to favor achieving Democratic goals through market-oriented policies. As Mr. Goolsbee has written: “Moral (p. C9) exhortation doesn’t change people’s behavior. Prices do.” Given their respective professions, the two are also more irreverent than you may expect: Mr. Goolsbee was once a member of an improvisational comedy group.

. . .

Both the Clinton and Obama campaigns are now playing catch-up on policy ideas. John Edwards, who’s running third in fund-raising and the early polls, has tried to grab attention by releasing a series of specific proposals. Rather than bringing economists into his campaign, he is relying on a network of former aides from Capitol Hill to help him sort through ideas. (One Edwards proposal — on tax simplification — was originally Mr. Goolsbee’s, in fact.)

I have never met Goolsbee, or heard him speak, but I have read a couple of his articles on the economics of the internet, and other subjects, and regularly read his economics articles in the New York Times.  He often writes interesting, creative stuff that is fun to read.

I had assumed that Obama was a standard big-government Democrat, although I liked what I read about what he was reported to be saying in Africa.  Maybe his economic policies would be more promising than I assumed.

On the other hand, I am convinced that the fight against terrorism is the crucial issue of our time, and I haven’t heard much from Senator Obama on that, besides hopping on the bandwagon of Bush-bashers.  What would he constructively do to protect us from the bad guys?

 

Mexican Federal Taxi “Charters” Increase Taxi Prices

 

     A non-federally-chartered taxi leaves the Cancun Hilton, headed for the Cancun airport, charging $23.  An identical, but federally-chartered cab, making the reverse trip, charges $40.  (Photo by Art Diamond.)

 

When we arrived at the Cancun airport we faced a chaotic environment where many Mexicans were yelling at us to buy taxi tickets.  After buying a ticket for $40, someone escorted us to a crowded, chaotic place to wait for a cab.  We waited and waited in the noise and the heat.  At some point, my daughter Jenny commented, "These people need to get organized."

Yes, Jenny they sure do!  And you might think that what they need in order to get organized, is for the government to come in to organize them.

But it turns out that the government has already come in.  Only federally charged taxis are allowed to take passengers from the airport to the hotel zone.  The price is fixed at $40.  On the other hand, any taxi may take passengers back to the airport, from the hotel zone.  The base price for a return trip was $23 .  (I added a $2 tip out of sympathy for the cabbie not driving a federally anointed cab.)

So, yes, these people need to get organized, and the best way to do that is to get their government out of their way, so that they can organize themselves through the free market.

 

Note:  relevant guide book passage:  "[Returning to the airport] the rate will be much less for the trip from the airport.  (Only federally chartered taxis may take fared from the airport, but any taxi may bring passengers to the airport.)"  (p. 78)

Nordhaus Critiques Stern’s Case for Environmental Disaster


My only major disagreement with the commentary below, is that I have much more confidence that, given free market institutions, our descendants will have the incentives, energy, and ingenuity, to solve the problems that they will face.

 

The Stern Review’s most influential critic has probably been William Nordhaus, a 65-year-old Yale professor who is as mainstream as economists come.  Jeffrey D. Sachs, the anti-poverty advocate, calls Mr. Nordhaus “about the most reasonable man I know.”

He was the first speaker after lunch, and, of course, he had some very nice things to say about Sir Nicholas. The report “was presented here very eloquently by a distinguished scholar,” Mr. Nordhaus said. But then came the juicy stuff: the Stern Review “commits cruel and unusual punishment on the English language,” Mr. Nordhaus said, and the British government’s opinion on climate change is no more infallible than was its prewar view about weapons of mass destruction in Iraq.

This was fairly tame compared with the comments of another Yale economist, Robert O. Mendelsohn. “I was awestruck,” he said, comparing Sir Nicholas to “The Wizard of Oz.” But “my job is to be Toto,” he added, in the same good-humored tone Mr. Nordhaus used. “Is it in fact The Wizard of Oz, or is it nothing at all?”

The two professors raised some questions about the science in the Stern Review. Mr. Nordhaus wondered if carbon emissions and temperatures would rise as quickly as the report suggests, and Mr. Mendelsohn predicted that people would learn to adapt to climate change, reducing its ultimate cost.

But their main objection revolved around something called the discount rate. The Stern Review assumed that a dollar of economic damage prevented a century from now (adjusted for inflation) is roughly as valuable as a dollar spent reducing emissions today. In effect, the report argues for spending the money to cut emissions because future generations have as much claim on resources as current generations. “I’ve still not heard a decent ethical argument” for believing otherwise, Sir Nicholas said at the debate.

I’m guessing that your instinct is to agree with him. Mine certainly was. The problem is that none of us actually behave this way. If we really thought that our great-grandchild deserved our money as much as we do, we would never go out to dinner again. Instead, we would invest the $50 we would have spent on dinner, confident that it would grow over time and become perhaps $1,000 for our great-grandchild to put toward health care, education or a supercomputer. Any of that is preferable to our measly dinner.

But a dollar today truly is more valuable than a dollar a century from now. For one thing, your great-grandchild will almost certainly be richer than you are and won’t need your money as much as you do. So spending a dollar on carbon reduction today to avoid a dollar’s worth of economic damage in 2107 doesn’t make sense. We would be better off putting the money toward something likely to have a higher return than alternative energy, like education.

Technically, then, Sir Nicholas’s opponents win the debate. But in practical terms, their argument has a weak link. They are assuming that the economic gains from, say, education will make future generations rich enough to make up for any damage caused by climate change. Sea walls will be able to protect cities; technology can allow crops to grow in new ways; better medicines can stop the spread of disease.

A Public Choice Theory of the Absence of Evidence of the Exodus of the Israelites

The economic theory of public choice is often viewed as having begun with Buchanan and Tullock’s The Calculus of Consent.  The theory seeks to explain the behavior of government, and government officials, as arising from the same self-interested motives as are used by economists to explain the behavior of free markets, firms, and consumers.

 

It didn’t look like much — some ancient buried walls of a military fort and a few pieces of volcanic lava. The archaeologist, Dr. Zahi Hawass, often promotes mummies and tombs and pharaonic antiquities that command international attention and high ticket prices. But this bleak landscape, broken only by electric pylons, excited him because it provided physical evidence of stories told in hieroglyphics. It was proof of accounts from antiquity.

That prompted a reporter to ask about the Exodus, and if the new evidence was linked in any way to the story of Passover. The archaeological discoveries roughly coincided with the timing of the Israelites’ biblical flight from Egypt and the 40 years of wandering the desert in search of the Promised Land.

“Really, it’s a myth,” Dr. Hawass said of the story of the Exodus, as he stood at the foot of a wall built during what is called the New Kingdom. 

. . .  

Recently, diggers found evidence of lava from a volcano in the Mediterranean Sea that erupted in 1500 B.C. and is believed to have killed 35,000 people and wiped out villages in Egypt, Palestine and the Arabian Peninsula, officials here said. The same diggers found evidence of a military fort with four rectangular towers, now considered the oldest fort on the Horus military road.

But nothing was showing up that might help prove the Old Testament story of Moses and the Israelites fleeing Egypt, or wandering in the desert. Dr. Hawass said he was not surprised, given the lack of archaeological evidence to date. But even scientists can find room to hold on to beliefs.

Dr. Mohamed Abdel-Maqsoud, the head of the excavation, seemed to sense that such a conclusion might disappoint some. People always have doubts until something is discovered to confirm it, he noted.

Then he offered another theory, one that he said he drew from modern Egypt.

“A pharaoh drowned and a whole army was killed,” he said recounting the portion of the story that holds that God parted the Red Sea to allow the Israelites to escape, then closed the waters on the pursuing army.

“This is a crisis for Egypt, and Egyptians do not document their crises.”

Private Money Can Top Government Money in Space, as in IT

 

Lots of people are building new IT companies. You can start a company and sell it to Yahoo! or Google in a couple of years. But so can anyone else. Aerospace is different. To paraphrase John F. Kennedy in 1962: We choose to go to the moon not because it’s easy, but because it’s hard.

That’s why, as a long-time investor in IT and Internet start-ups, I’m now spending more and more time on private aviation and commercial space start-ups. I’m trailing an illustrius crew of IT pioneers: Elon Musk (Space-X, rockets, formerly with PayPal), Vern Raburn (Eclipse Aviation, very light jets, formerly at Microsoft, Symantec and Lotus), Jeff Bezos (Blue Origin, rockets, and still at Amazon, too!), Jeff Greason (XCOR, rockets and formerly with Intel) and Ed Iacobucci (DayJet, air taxi operator, and founder of Citrix).

. . .

On the space side, there’s a . . . strong parallel with the world of IT. The establishment in "space" is the government and especially the military, just as it once was (along with academia) for the Internet. I remember the days when commerce on the Internet was considered sleazy—but look at the innovations and productivity it unleashed.

In the same way, the current priests of space are dismayed by the privately funded space start-ups—unsafe, sleazy, frivolous. Imagine: Ads on the side of a rocket ship! Well, why not, if it helps pay for the fuel… and the R&D that designed the thing?

Medicare Part D Privatization “Has Succeeded”

 

The author of the commentary excerpted below, won the Nobel Prize in economics in 2000. 

 

Last year, Medicare underwent a major expansion with the addition of Part D prescription drug coverage. A controversial feature of this new program was its organization as a market in which consumers could choose among various plans offered competitively by different insurers and HMOs, rather than the single-payer, single-product model used elsewhere in the Medicare system. Proponents of this design touted the choices it would offer consumers, and the benefits of competition for product quality and cost; opponents objected that consumers would be overwhelmed by the complexity of the market, and that it was unnecessarily generous to pharmaceutical and insurance companies.

Part D is a massive social experiment on the ability of a privatized market to deliver social services effectively. With the support of the National Institute on Aging, my research group has monitored consumer choices and outcomes from the new Part D market.  . . .

. . .

My overall conclusion is that, so far, the Part D program has succeeded in getting affordable prescription drugs to the senior population. Its privatized structure has not been a significant impediment to delivery of these services. Competition among insurers seems to have been effective in keeping a lid on costs, and assuring reasonable quality control. We do not have an experiment in which we can determine whether a single-product system could have done as well, or better, along these dimensions, but I think it is reasonable to say that the Part D market has performed as well as its partisans hoped, and far better than its detractors expected.

Communist Hugo Chávez: Is He Loco to Fight Inflation with the Locha?

 

   Hugo Chávez expects to end inflation by bringing back the "locha" 12 ½-cent coin (held in this picture by coin dealer Antonio Allesandrini).  Source of photo:  online version of the NYT article quoted and cited below.   

 

(p. 8)  CARACAS, Venezuela, March 17 — Of all the startling measures announced by President Hugo Chávez this year, from the nationalization of major utilities to threats of imprisonment for violators of price controls, none have baffled economists quite like his venture into monetary reform.

First, Mr. Chávez said the authorities would remove three zeroes from the denomination of the currency, the bolívar. Then he said the new bolívar, worth 1,000 old bolívars, would be renamed the “bolívar fuerte,” or strong bolívar.

Finally, at the behest of Mr. Chávez, the central bank said this week that it would reintroduce a 12.5-cent coin, a symbol of Venezuela’s prosperity in the 1960s and 1970s before freewheeling oil booms ended in abrupt devaluations, after three decades out of circulation.

Mr. Chávez champions these ideas, which will take effect in January, as ways to combat inflation, which in recent weeks crept up to 20 percent, the highest in Latin America.  . . .

. . .

“We’re witnessing policy in the form of window dressing, all carried out at the whim of one man whose strong point is not economics,” said Hugo Faría, an economist at the Institute of Higher Management Studies, a private business school here. “Anyone who sees a 12 ½-cent coin as a remedy for this country’s problems isn’t thinking too clearly.”

George Stigler on Astrology

 

I remember George Stigler saying (I think in conversation with me, but maybe as an aside in a lecture), that at first he had been inclined to reject a paper for the JPE that empirically tested astrology.  His reason was that, while he liked what the authors were doing, he was not sure that what they were doing, most appropriately belonged in an economics journal.

But when the authors convinced him that they would not be able to publish it anywhere else, he changed his mind and published it.

The episode tells us something about Stigler, and something about scientific method.  About Stigler, the episode provides strong evidence of the importance that Stigler placed on evidence, relative to theory.

On scientific method, the episode can be taken as an illustration of Karl Popper’s distinction between the context of discovery and the context of justification.  There are many sources of hypotheses (the context of discovery).  Famously, Kepler’s inspiration for the elliptical paths of planets, had a somewhat mystical source in the "perfect" solids.  But what makes a theory "scientific" is not its context of discovery, but its context of justification, viz., is the theory subjected to empirical test?

Hypotheses are not ruled out of science ab initio, but by being inconsistent with the evidence.  I agree with this view, which explains why I am a (passive) member of the Society for Scientific Exploration, which is devoted to the empirical testing of politically incorrect theories (such as UFOs, the Shroud of Turin, ESP, the Loch Ness Monster, etc.)

 

The JPE astrology article, accepted by Stigler as editor, was: 

Bennett, James T., and James R. Barth. "Astronomics: A New Approach to Economics?" Journal of Political Economy 81, no. 6 (Nov.-Dec. 1973): 1473-75.

 

A more recent empirical test of an astrological hypothesis is:
