Ehrlich Won Genius Award; Simon Won No Award, But Simon Was Right

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

A new United Nations report called "State of the Future" concludes: "People around the world are becoming healthier, wealthier, better educated, more peaceful, more connected, and they are living longer."

. . .

To what do we owe this improvement? Capitalism, according to the U.N. Free trade is rightly recognized as the engine of global prosperity in recent years. In 1981, 40% of the world’s population lived on less than $1 a day. Now that percentage is only 25%, adjusted for inflation. And at current rates of growth, "world poverty will be cut in half between 2000 and 2015" — which is arguably one of the greatest triumphs in human history. Trade and technology are closing the global "digital divide," and the report notes hopefully that soon laptop computers will cost $100 and almost every schoolchild will be a mouse click away from the Internet (and, regrettably, those interminable computer games).

It also turns out that the Malthusians (who worried that we would overpopulate the planet) got the story wrong. Human beings aren’t reproducing like Norwegian field mice. Demographers now say that in the second half of this century, the human population will stabilize and then fall. If we use the same absurd extrapolation techniques demographers used in the 1970s, Japan, with its current low birth rate, will have only a few thousand citizens left in 300 years.

I take special pleasure in reciting all of this global betterment because my first professional job was working with the "doom-slaying" economist Julian Simon. Starting 30 years ago, Simon (who died in 1998) told anyone who would listen — which wasn’t many people — that the faddish declinism of that era was bunk. He called the "Global 2000" report "globaloney." Armed with an arsenal of factual missiles, he showed that life on Earth was getting better, and that the combination of free markets and human ingenuity was the recipe for solving environmental and economic problems. Mr. Ehrlich, in response, said Simon proved that the one thing the world isn’t running out of "is lunatics."

Mr. Ehrlich, whose every prediction turned out wrong, won a MacArthur Foundation "genius award"; Simon, who got the story right, never won so much as a McDonald’s hamburger. But now who looks like the lunatic? This latest survey of the planet is certainly sweet vindication of Simon and others, like Herman Kahn, who in the 1970s dared challenge the "settled science." (Are you listening, global-warming alarmists?)

The media’s collective yawn over "State of the Future" is typical of the reaction to just about any good news. When 2006 was declared the hottest year on record, there were thousands of news stories. But last month’s revised data, indicating that 1934 was actually warmer, barely warranted a paragraph-long correction in most papers.

Strong, But Slower, Growth in Online Sales

Source of graph: online version of the NYT article cited below.

(p. 1) SAN FRANCISCO, June 16 — Has online retailing entered the Dot Calm era?

Since the inception of the Web, online commerce has enjoyed hypergrowth, with annual sales increasing more than 25 percent over all, and far more rapidly in many categories. But in the last year, growth has slowed sharply in major sectors like books, tickets and office supplies.

Growth in online sales has also dropped dramatically in diverse categories like health and beauty products, computer peripherals and pet supplies. Analysts say it is a turning point and growth will continue to slow through the decade.

. . .

Forrester Research, a market research company, projects that online book sales will rise 11 percent this (p. 16) year, compared with nearly 40 percent last year. Apparel sales, which increased 61 percent last year, are expected to slow to 21 percent. And sales of pet supplies are on pace to rise 30 percent this year after climbing 81 percent last year.

Growth rates for online sales are slowing down in numerous other segments as well, including appliances, sporting goods, auto parts, computer peripherals, and even music and videos. Forrester says that sales growth is pulling back in 18 of the 24 categories it measures.

. . .

The turning point comes as most adult Americans, and many of their children, are already shopping online. That means Internet stores are not getting a flurry of new shoppers to spur the kind of growth tht the industry is accustomed to. There is a boom in the number of foreigners coming online, but shipping items overseas can limit that market as a source of growth.

. . .

John Morgan, an economics professor from the Haas School of Business at the University of California, Berkeley, said he expected online commerce to continue to increase, partly because it remains less than 1 percent of the overall economy. “There’s still a lot of head room for people to grow,” he said.

Latin America Discourages Entrepreneurs

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

(p. A18) Economist Joseph Schumpeter (1883-1950) may be best known for his innovative work showing the link between entrepreneurial discovery and economic progress.

But as Carl Schramm, president of the Kauffman Foundation of Entrepreneurship has pointed out, Schumpeter’s insights about risk-takers didn’t make him an optimist.

In a speech last year to European finance ministers in Vienna, Mr. Schramm explained Schumpeter’s fears: He "worried that entrepreneurial capitalism would not flourish because the bureaucracies of modern government and big corporations would dampen innovation — the process of ‘creative destruction’ would be too ungovernable for a modern, Keynesian-regulated economy to tolerate." As a result, Mr. Schramm said, Schumpeter thought that "the importance of entrepreneurs would fade over time as capitalism sought predictability from governments who would plan economic activity as well as order social benefits."

Mr. Schramm’s comments caught my attention because they so accurately describe Latin America. There the entrepreneur has been all but run out of town by the bureaucracies that Schumpeter feared. Growth has suffered accordingly.

The World Bank’s annual "Doing Business" survey, released last week, demonstrates the point. The 2008 survey, which evaluates the regulatory climate for entrepreneurs in 178 countries, finds that Latin America and the Caribbean was the slowest reforming region this year and that it "is falling further behind other regions in the pace" of reform.

. . .

The most important lesson for Latin America from the World Bank’s report is that its competitors around the world are working to unleash entrepreneurial spirits, and doing nothing is not an option. As Mr. Schramm told his Vienna audience, "Schumpeter saw what a century of evidence would prove: Socialism has not sustained economic growth." Now, if only more Latin American policy makers would catch on.

Suing the Pants Off Private Enterprise: Illustrating the Case for Tort Reform

The Dry Cleaners that was sued for $67.3 million dollars, to compensate a Washington, D.C. judge for a lost pair of pants. Source of the photo: online version of the NYT article cited below.

WASHINGTON, June 12 — Roy L. Pearson Jr. wanted to dress sharply for his new job as an administrative law judge here. So when his neighborhood dry cleaner misplaced a pair of expensive pants he had planned to wear his first week on the bench, Judge Pearson was annoyed.

So annoyed that he sued — for $67.3 million.

The case of the judge’s pants, which opened for trial in a packed courtroom here on Tuesday, has been lampooned on talk radio and in the blogosphere as an example of American legal excess. And it has spurred complaints to the District of Columbia Bar and city officials from national tort reform and trial lawyer groups worried about its effect on public trust in the legal system.

“I don’t know of any other cases that have been quite this ridiculous,” said Paul Rothstein, a professor of law at Georgetown University.

. . .

“You are not a we, you are an I,” Judge Bartnoff said in one of several testy exchanges with Judge Pearson, 57, who is representing himself. “You are seeking damages on your own behalf, and that is all.”

Later, while recounting the day he says the cleaners tried to pass off a cheaper pair of pants as his, Judge Pearson began to cry, asking for a break and dabbing tears as he left the courtroom.

Thales of Miletus Lives

Source of book image: http://store.43folders.com/books-3-1400063515-The_Black_Swan_The_Impact_of_the_Highly_Improbable

This is part entertaining rant and part serious epistemology. I’ve finished 9 of 19 chapters so far–almost all of my reading time spent smiling.

Historians of Greek philosophy used to tell the story of one of the first philosophers, Thales of Miletus, that he once was watching the stars, and fell into a well. The citizens of Miletus made fun of him being an impractical philosopher. To prove them wrong, he used his knowledge to corner the market in something, and made a fortune.

Not a very plausible story, but appealing to us philosophers. (Like Thales, we like to think we could all be rich, if we didn’t have higher goals.)

Well apparently Taleb is the real Thales. He wanted to be a philosopher, got rich on Wall Street using his epistemological insights, and is now using his wealth to finance his musings on whatever he cares to muse on.

Beautiful!

Here’s an amusing sentence that broadened my grin. (It was even more amusing, and profound, in context, but I don’t have time to type in the context for you.)

(p. 87) If you are a researcher, you will have to publish inconsequential articles in "prestigious" publications so that others say hello to you once in a while when you run into them at conferences.

Buchanan on Hayek, Rawls and Nozick

Sandy Peart talking to James Buchanan. Source of photo: me.

In an earlier blog entry, I mentioned a comment on disagreeing with journal referees, made by James Buchanan in conversation at the closing dinner of the 2007 Summer Institute for the Preservation of the History of Economics.

Hayek also came up at the dinner with Buchanan. Buchanan mentioned that he was not as enthused about Hayek’s later work, including The Fatal Conceit, and Law, Legislation and Liberty—he thought the best might have been The Constitution of Liberty.

He mentioned that some foundation had funded a couple of conferences in Europe of top free market scholars to offer advice to Hayek. They told Hayek that his manuscript was a mess, and that it would be an embarrassment to him to publish it. But he said he was already under contract. (I think this comment referred to The Fatal Conceit.) So someone (Bruce Bartlett?) helped Hayek clean it up.

Buchanan also spoke highly about Rawls. I think I mentioned that Hayek had said that his approach was similar to Rawls. I think Buchanan said he did not think that comment was surprising.

I also believe I remember Buchanan saying that he thought more highly of Rawls than of Nozick.

Sherwin Rosen Approves a Positive Review of Rosenberg’s Book

Another of Sherwin Rosen’s minor acts of methodological delinquency, this time in his role as co-editor of the Journal of Political Economy, was his asking me to review Alexander Rosenberg’s criticism of the economics profession for drifting further and further into irrelevant mathematical puzzle-solving. My review was basically favorable to Rosenberg, and my memory is that Rosen was quite content with my review.

Global Warming is No Threat to North Atlantic Current

A view of part of the Greenland ice sheet. Source of the photo: online version of the NYT article quoted and cited below.

(p. D3) OSLO — Mainstream climatologists who have feared that global warming could have the paradoxical effect of cooling northwestern Europe or even plunging it into a small ice age have stopped worrying about that particular disaster, although it retains a vivid hold on the public imagination.

The idea, which held climate theorists in its icy grip for years, was that the North Atlantic Current, an extension of the Gulf Stream that cuts northeast across the Atlantic Ocean to bathe the high latitudes of Europe with warmish equatorial water, could shut down in a greenhouse world.

Without that warm-water current, Americans on the Eastern Seaboard would most likely feel a chill, but the suffering would be greater in Europe, where major cities lie far to the north. Britain, northern France, the Low Countries, Denmark and Norway could in theory take on Arctic aspects that only a Greenlander could love, even as the rest of the world sweltered.

All that has now been removed from the forecast. Not only is northern Europe warming, but every major climate model produced by scientists worldwide in recent years has also shown that the warming will almost certainly continue.

“The concern had previously been that we were close to a threshold where the Atlantic circulation system would stop,” said Susan Solomon, a senior scientist at the National Oceanic and Atmospheric Administration. “We now believe we are much farther from that threshold, thanks to improved modeling and ocean measurements. The Gulf Stream and the North Atlantic Current are more stable than previously thought.”

. . .

“The ocean circulation is a robust feature, and you really need to hit it hard to make it stop,” said Eystein Jansen, a paleoclimatologist who directs the Bjerknes Center for Climate Research, also in Bergen. “The Greenland ice sheet would not only have to melt, but to dynamically disintegrate on a huge scale across the entire sheet.”

The worst imaginable collapse would likely take centuries to play out, he said. Any disruption to the North Atlantic Current — whose volume is 30 times greater than all the rivers in the world combined — would thus occur beyond the time horizon of the United Nations climate panel.

When Sherwin Rosen Stunned the Fifth World Congress of the Econometric Society

I remember hearing Sherwin Rosen speak to a good-sized auditorium of technical economists at a plenary session of the Fifth World Congress of the Econometric Society in 1985.[i] Rosen was proceeding in his typically bemused style, when he suggested to the stunned audience that they might benefit from re-reading Alfred Marshall. I remember him saying that there are some things in Marshall that we don’t talk about any more, but that we should still talk about. I specifically remember him mentioning that Marshall had said that the success of the institution of contract depended on the correct expectation of a certain level of ethical behavior among the participants in the economy. I wish I could remember the specifics better, but Rosen’s auditors were visibly dismayed, and I supposed that they were thinking something like: ‘read Marshall?, here was the sad sight of a once proud theoretician, going soft and senile.’

[i]I remember a large auditorium-like venue for the session, but could not remember any other session details, so I dug out a copy of the program for the meetings. The only plenary session participation listed for Rosen, was his serving as a discussant for Oliver Hart and Bengt Holmstrom’s “Theory of Contracts” paper, which was delivered on August 19, 1985 (see: “Program . . .,” 1986, p. 471). In searching through Rosen’s publications, I cannot find any evidence that his comment was ever published. In an email response (email dated Nov. 19, 2006) to my inquiry, Bengt Holmstrom has replied: “I know that his comment was not published.”

David Warsh on Paul Romer’s ‘Triumph of Formalism’

David Warsh prepares to speak as Sandra Peart introduces him at the HES meetings at George Mason. Source of photo: me.

David Warsh in his plenary address to the History of Economics Society on June 9, 2007, recounted a version of the account that he gives in his 2006 book Knowledge and the Wealth of Nations. (A key part of this story was also told in an article in the Sunday magazine section of The New York Times.)

Here I concentrate on the plenary lecture presentation.

Warsh said that he is the first to give Romer his due; that Romer has managed to alienate the economists both at Chicago and at MIT. (Well, maybe, but Tom Friedman sure gives Romer a lot of attention and praise in his best-selling The World is Flat.) Warsh also said that he (Warsh) has been accused of writing a hagiography of Romer.

Warsh identifies the key contribution of Romer as being that he identifies the key properties of knowledge, namely that it is nonrivalrous and nonexcludible. He claims that Romer was the first to see this, and so is responsible for beginning the crucial field of the economics of knowledge.

Further, Warsh claims that the economics profession only achieved this insight when Romer found a way to incorporate knowledge in his formal models.

This story, Warsh says, is a triumph of formalism; only through formalism could such an important advance have been made.

At this point in the presentation, I became rather annoyed—I had my hand up during most of the question session, but Warsh chose not to call on me. (In fairness, I was seated on his far left, though at the front, so it is possible that he did not see me.)

What I told Warsh afterwards was that the lesson from this episode is the exact opposite of the one he claims—it is not an example of the triumph of formalism, but rather an example of the shame of formalism.

Long before Romer, others had pointed out the nonrivalry and nonexcludibility of knowledge. E.g., Arrow briefly in a famous essay (1962), and Harry Johnson at greater length in an obscure essay (1972).

The requirement that serious knowledge requires formalization before it is taken seriously, meant that economists ignored for several decades, what had been nonformally known. It is to the shame of formalism that for decades useful issues were ignored.

And even more strongly, to say that Romer is responsible for founding the economics of knowledge is to add insult to injury to the economists who had actually founded this field: economists such as Richard Nelson, Nathan Rosenberg, Zvi Griliches and Edwin Mansfield.

Not only was their work largely ignored for decades, but a leading advocate and exemplar of the formalist methodology responsible for the ignorance, is himself given credit for their achievements.
