Marginal Revolution’s Most Popular Posts from 2011

1. College has been oversold. It’s hard to explain which posts go viral but this post, based on material from my e-book Launching the Innovation Renaissance, was a monster generating over 500 comments, 3000 likes and 800 tweets. The follow-up on puppeteerring in a wintry economic climate was also popular although not in the top ten.

2. Teacher’s Don’t Like Creative Students. Another monster with fewer page views than #1 but over 3000 likes and nearly 4000 tweets!

3. Philosophy Referee Signals.

4. Be Safe Break the Law, on the 55mph speed limit.

5. Possible progress in medicine, a link-post from Tyler noting a new drug that can kill many viruses.

6. What is quirky about the United States? A question from Tyler that generated many comments.

7. The Mexican Mafia another of mine that went viral with links from Time, Instapundit and Reddit.

8.  World Income Equality a graph showing how poor Americans are richer than rich Indians.

9. Explaining France, a post from Tyler explaining, well you know.

10. Common mistakes of right wing and market economists, a nice meaty post from Tyler, just a little bit more popular than Common mistakes of left-wing economists.

A few other notable posts in the top 25 were my posts on cities, India’s Voluntary City and Cities as Hotels, Tyler’s post on the S&P downgrade, my post on The Fruits of Immigration, which was  mostly just quotations but I worked hard on the final line which many people then linked to, and my post on The Great Male Stagnation.

Several posts from previous years continued to be popular. What Happened to M. Night Shyamalan? from 2010 was again popular this year probably because Slate expanded the idea into a feature called Hollywood’s Career-O-Matic.

The importance of writing a good title is shown by Tyler’s 2007 posts Why did the Soviet Union fall? and How many children should you have? neither of which generated many comments but both of which show up early in Google searches of precisely these questions. My 2008 post What is New Trade Theory? on Krugman’s Nobel may also continue to attract attention for this reason.

2012 here we come!

Claims about potato chips

You may be surprised to learn that potato chips are a health food; almost all chips (expensive or not) emphasized the healthiness of their products by using phrases like “low fat”, “healthier”, “no cholesterol”, or “lowest sodium level”. But these health-related claims occur on expensive chips 6 times as often as on inexpensive chips (6 times per bag versus once per bag). This difference in health language is not, as far as we can tell, due to actual differences in the chips. No chips in our sample contain trans fats, but only 2 out of the 6 inexpensive chips talk about it. By contrast, every one of the 6 expensive chips mentions the lack of trans fats.

Expensive chips also turn out to be much more natural. Phrases such as “natural”, “real”, or “nothing artificial” are 2.5 times more likely to be mentioned on expensive bags (7 times on each expensive bag but under 3 times on each inexpensive bag).

Another way to differentiate is to use negative markers, words like “never”, “not”, or “no” (“never fried”, “we don’t wash out the natural potato flavor”, “no wiping your greasy chip hand on your jeans”). Negation emphasizes bad qualities that a chip does not have, subtly suggesting that other brands have this bad quality. To get a more fine-grained analysis, we also regressed the number of negative words against the price. We found that a bag of potato chips costs 4 cents more per ounce for every additional negative word on the bag.

Finally, expensive chips are 5 times more likely to distinguish themselves from other chips, using comparative phrases like “less fat than other leading brands”, “best in America”, “in a class of their own”. or “a crunchy bite you won’t find in any other chip”. Where text on the inexpensive chips focuses on the chips themselves, ads for expensive chips emphasize their differences from “lesser” chips.

…Mentions of tradition occurred more than twice as often on inexpensive chips. Our linear regression showed that every time a family or an American locale is mentioned, the price per ounce of the chips drops 10 cents. The inexpensive chips thus represent a model of authenticity rooted in family traditions and family-run companies, and set in regional locations throughout America.

That is from Dan JurafskyHis blog, on food and language, is interesting throughout.

Why is India so low in the Pisa rankings?

That is a request from J. and here is one recent story, with much more at the link:

A global study of learning standards in 74 countries has ranked India all but at the bottom, sounding a wake-up call for the country’s education system. China came out on top.

On this question, you can read a short Steve Sailer post, with comments attached.  Here are my (contrasting) observations:

1. A big chunk of India is still at the margin where malnutrition and malaria and other negatives matter for IQ.  Indian poverty is the most brutal I have seen, anywhere, including my two trips to sub-Saharan Africa or in my five trips to Haiti.  I don’t know if Pisa is testing those particular individuals, but it still doesn’t bode well for the broader distribution, if only through parental effects.

2. Significant swathes of Indian culture do not do a good job educating women or protecting their rights, even relative to some other very poor countries.  On educational tests the female students are at a marked disadvantage and that will drag down the average.

3. Countries taking the test for the first time may face a disadvantage in manipulating the results to their advantage; admittedly this cannot account for most of the poor performance.

4. Indian agricultural productivity is abysmal, in large part due to legal restrictions.  I discuss this in more detail in my next book An Economist Gets Lunch, due out in April.  That hurts the quality of life and opportunities for hundreds of millions of Indians, including of course children.

Overall, India has a lot of low-hanging fruit, but the country has further to go than many observers realize.  A quadrupling of per capita income would put them at what, the level of Thailand?

The new Robert Gordon paper on productivity

Via Reihan, here is the abstract and paper:

This paper provides three perspectives on long-run growth rates of labor productivity (LP) and of multi-factor productivity (MFP) for the U. S. economy. It extracts statistical growth trends for labor productivity from quarterly data for the total economy going back to 1952, provides new estimates of MFP growth extending back to 1891, and tackles the problem of forecasting LP and MFP twenty years into the future.

The statistical trend for growth in total economy LP ranged from 2.75 percent in early 1962 down to 1.25 percent in late 1979 and recovered to 2.45 percent in 2002. Our results on productivity trends identify a problem in the interpretation of the 2008-09 recession and conclude that at present statistical trends cannot be extended past 2007. For the longer stretch of history back to 1891, the paper provides numerous corrections to the growth of labor quality and to capital quantity and quality, leading to significant rearrangements of the growth pattern of MFP, generally lowering the unadjusted MFP growth rates during 1928-50 and raising them after 1950. Nevertheless, by far the most rapid MFP growth in U. S. history occurred in 1928-50, a phenomenon that I have previously dubbed the “one big wave.”

The paper approaches the task of forecasting 20 years into the future by extracting relevant precedents from the growth in labor productivity and in MFP over the last seven years, the last 20 years, and the last 116 years. Its conclusion is that over the next 20 years (2007-2027) growth in real potential GDP will be 2.4 percent (the same as in 2000-07), growth in total economy labor productivity will be 1.7 percent, and growth in the more familiar concept of NFPB sector labor productivity will be 2.05 percent. The implied forecast 1.50 percent growth rate of per-capita real GDP falls far short of the historical achievement of 2.17 percent between 1929 and 2007 and represents the slowest growth of the measured American standard of living over any two-decade interval recorded since the inauguration of George Washington.

GiveWell

GiveWell, by far the best charity evaluator working today, has a new top ranked charity, the Against Malaria Foundation. Why is VillageReach, their best ranked charity for several years, no longer at the top? First, GiveWell is ranking more charities and charities are now more willing to provide GiveWell the kind of detailed information on outcomes that GiveWell demands. Thus, more charities are vying for the top spot. Even more important is this:

VillageReach was our top-rated organization for 2009, 2010 and much of 2011 and it has now received over $2 million due to GiveWell’s recommendation. We do not believe that VillageReach has short-term funding needs…

When was the last time that a charity or evaluator told you that due to successful fund-raising there are now more urgent needs elsewhere? Impressive. As I have for several years, I will be following GiveWell’s advice and donating to the Against Malaria Foundation and several of GiveWell’s other top charities.

Andrew Lo reviews 21 books on the financial crisis

The paper and abstract are here:

Abstract:
The recent financial crisis has generated many distinct perspectives from various quarters. In this article, I review a diverse set of 21 books on the crisis, 11 written by academics, and 10 written by journalists and one former Treasury Secretary. No single narrative emerges from this broad and often contradictory collection of interpretations, but the sheer variety of conclusions is informative, and underscores the desperate need for the economics profession to establish a single set of facts from which more accurate inferences and narratives can be constructed.

It is an instructive look at how bad we are at discovering the truth and talking about it.  Here is part of his beginning:

To illustrate just how complicated it can get, consider the following “facts” that have become part of the folk wisdom of the crisis:

1. The devotion to the Efficient Markets Hypothesis led investors astray, causing them to ignore the possibility that securitized debt2 was mispriced and that the real-estate bubble could burst.

2. Wall Street compensation contracts were too focused on short-term trading profits rather than longer-term incentives. Also, there was excessive risk-taking because these CEOs were betting with other people’s money, not their own.

3. Investment banks greatly increased their leverage in the years leading up to the crisis, thanks to a rule change by the U.S. Securities and Exchange Commission (SEC).

While each of these claims seems perfectly plausible, especially in light of the events of 2007–2009, the empirical evidence isn’t as clear.

Starting on p.35, you can find a new take on the myth of the 2004 SEC change to Rule 15c3–1 (though see the first comment), relating to the supposed increase in leverage requirements from 12-1 to 33-1:

…it turns out that the 2004 SEC amendment to Rule 15c3–1 did nothing to change the leverage restrictions of these financial institutions. In a speech given by the SEC’s director of the Division of Markets and Trading on April 9, 2009 (Sirri, 2009), Dr. Erik Sirri stated clearly and unequivocally that “First, and most importantly, the Commission did not undo any leverage restrictions in 2004”. He cites several documented and verifiable facts to support this surprising conclusion, and this correction was reiterated in a letter from Michael Macchiaroli, Associate Director of the SEC’s Division of Markets and Trading to the General Accountability Office (GAO) on July 17, 2009, and reproduced in the GAO Report GAO–09–739 (2009, p. 117).

It is also shown that the higher leverage was common in the late 1990s.  There is more to the discussion, but it is time to reconsider this point.

Is the Fed our savior in financial regulation?

It seems odd to put up an actual substantive post on Christmas day, nonetheless here is my New York Times column on financial regulation.

Despite these problems, the United States may oddly enough be facing this new financial turmoil in a relatively safe position, though whether it’s safe enough remains to be seen. The Federal Reserve took the lead on future capital requirements just last week, but for the shorter run there is a more important Fed policy move. Starting in late 2008, as a response to our financial crisis, the Fed bought government and mortgage securities from banks on a very large scale.

Bank reserves at the Fed rose from virtually nothing to more than $1.6 trillion. Then the Fed paid interest on those reserves to help keep them on bank balance sheets.

It is estimated by Moody’s that America’s biggest banks now have liquid assets that are 3 to 11 times their short-term borrowings. In other words, it’s the cushion we’ve been seeking. Furthermore, a lot of those reserves sit in the American subsidiaries of large foreign-owned banks, protecting the European system, too.

This new safety comes not from regulatory micromanagement but rather from the creation of additional safe interest-bearing assets. While European economies have been losing safe assets through debt downgrades, the United States financial system has been gaining them.

Here is a relevant link from The Economist.  Here are links to Brad DeLong, David Wessel, and others, on related points.  Here is David Beckworth on safe assets.  The scarcity of safe assets is a critical theme today, and still we lack a satisfactory theory of collateral.  For instance, how many macroeconomists are well equipped to answer how “putting OTC derivatives on exchanges” will affect interest rates and output?

Here is another bit, which shows I have been changing my mind on interest on reserves:

The Fed’s stockpiled liquid reserves have met some heavy criticism. Hard-money advocates contend that they are a prelude to hyperinflation — although market forecasts and bond yields don’t bear this out — while proponents of monetary expansion have wished that banks would more actively lend out those reserves to stimulate the economy. That second view assumes that the financial crisis is essentially over, but maybe it’s not. As the euro zone crisis continues, it seems that Ben S. Bernanke has been a smarter central banker than we had realized.

Here is my earlier blog post, T-Bills as a substitute for financial regulation.  Here is my earlier post on monetary policy and bank recapitalization.  I view these as one piece, trying to explain why Bernanke has not been more aggressive with monetary policy along some dimensions.

The Fed (possibly) has foreseen that a scarcity of safe assets is a major macroeconomic problem — most of all in Europe — and has acted to limit this problem in the United States, even at the cost of having tighter money.  That means interest on reserves as a kind of synthetic T-Bills policy.  The interest induces demand to hold liquid reserves, which increases the buffer against a European financial implosion.  You can think of this policy as a substitute for the failure of regulators to get capital requirements right.

Overall, that means a monetary policy having to play the role of fiscal policy and regulatory policy, all at the same time.  No wonder so few people are happy with the outcome.

Through this lens, the Fed looks better, Congress, Dodd-Frank and the financial regulators look worse.  That dysfunctional government prevents an effective fiscal policy response — good and also politically sustainable projects — looks worse too.

Labor supply and taxes

This is from Michael P. Keane, from the new Journal of Economic Literature (gated, ungated here), emphasis added by me:

I survey the male and female labor supply literatures, focusing on implications for effects of wages and taxes. For males, I describe and contrast results from three basic types of model: static models (especially those that account for nonlinear taxes), life-cycle models with savings, and life-cycle models with both savings and human capital. For women, more important distinctions are whether models include fixed costs of work, and whether they treat demographics like fertility and marriage (and human capital) as exogenous or endogenous. The literature is characterized by considerable controversy over the responsiveness of labor supply to changes in wages and taxes. At least for males, it is fair to say that most economists believe labor supply elasticities are small. But a sizable minority of studies that I examine obtain large values. Hence, there is no clear consensus on this point. In fact, a simple average of Hicks elasticities across all the studies I examine is 0.31. Several simulation studies have shown that such a value is large enough to generate large efficiency costs of income taxation. For males, I conclude that two factors drive many of the differences in results across studies. One factor is use of direct versus ratio wage measures, with studies that use the former tending to find larger elasticities. Another factor is the failure of most studies to account for human capital returns to work experience. I argue that this may lead to downward bias in elasticity estimates. In a model that includes human capital, I show how even modest elasticities—as conventionally measured—can be consistent with large efficiency costs of taxation. For women, in contrast, it is fair to say that most studies find large labor supply elasticities, especially on the participation margin. In particular, I find that estimates of “long-run” labor supply elasticities—by which I mean estimates that allow for dynamic effects of wages on fertility, marriage, education and work experience—are generally quite large.

Where are they?

Hey, you!  Do you ever leave comments on MR?

NASA’s Kepler mission has discovered the first Earth-size planets orbiting a sun-like star outside our solar system. The planets, called Kepler-20e and Kepler-20f, are too close to their star to be in the so-called habitable zone where liquid water could exist on a planet’s surface, but they are the smallest exoplanets ever confirmed around a star like our sun.

The discovery marks the next important milestone in the ultimate search for planets like Earth. The new planets are thought to be rocky. Kepler-20e is slightly smaller than Venus, measuring 0.87 times the radius of Earth. Kepler-20f is slightly larger than Earth, measuring 1.03 times its radius. Both planets reside in a five-planet system called Kepler-20, approximately 1,000 light-years away in the constellation Lyra.

India and the Promise of Productivity

In the comments to Anti Chain Store Policies in India and America, “Lark” posted a long “refutation” from Triple Crisis of the “neo-liberal” arguments for retail reform in India. I will focus on one remarkable argument:

…experience across the world makes it incontrovertible that large retail companies displace many more jobs of petty traders, than they create in the form of employees. This has been true of all countries that have opened up to such companies, from Turkey in the 1990s to South Africa. Large retail chains typically use much more capital intensive techniques, and have much more floor space, goods and sales turnover per worker.

One estimate suggests that for every job Walmart (the largest global retail chain) creates in India, it would displace 17 to 18 local small traders and their employees. In a country like India, this is of major significance, since around 44 million people are now involved in retail trade (26 million in urban areas) and they are overwhelmingly in small shops or self-employed.

Of course this is no refutation, fewer jobs are precisely the point. What India needs is fewer jobs; fewer jobs in retail, fewer jobs in apparel and, most of all, fewer jobs in farming. India cannot become even a middle income country if most of its workers, for example, are farmers. To improve its standard of living, India must use fewer people to produce more agricultural output.

Fewer workers in farming (or retail) means more workers producing more goods in other industries. The same basic lesson holds throughout an economy, it is the declining sectors that allow other sectors to advance. Instantaneously? Immediately? With higher wages for every worker? No. Transitions always involve some pain; creation always involves some destruction; growth always involves change. The alternative, however, is stagnation.

The politics of growth are difficult because those who lose from change are always present and are often more numerous and perhaps even more deserving than the present winners, the capitalists, the business people, the international mega corps; but today’s losses and gains are fleeting, the permanent winners are the workers and consumers of the future who will know only the benefits of productivity.

That was then, this is now

In 2004, I wrote this to Alex:

The United States remains a strong and prosperous country. Our infrastructure, national culture of innovation, human capital, and economic dynamism are unparallelled in world history. The Bush fiscal policies, whatever their irresponsibilities, costs, and drawbacks, haven’t changed those core facts.

So I walked down to Alex’s office and issued him the following challenge: if you think I am wrong, sell all your stocks and go short on U.S. Treasury securities (and long on Brazil, if you wish!). With all the money you will make, you can buy out my half of this blog.

In my own defense, 2004 was the year when the available run of productivity statistics was looking the best, and there was no reason to think the 2001-2004 numbers were biased or misleading.

For the pointer I thank…Alex.

p.s. he didn’t do it.

Only joking

Nothing to see here, move on people…

Safaripark Beekse Bergen, near the Dutch town of Tilburg, boasts nine lions, 13 giraffes and a herd of almost 30 zebra. But this month the theme park reported sightings of an even more remarkable beast – a previously extinct specie, the Dutch guilder.

Thousands of guilders flooded into the park’s cash registers after it announced it would accept the former national currency for one weekend, in a promotion tied to the European Council summit earlier this month. At the ticket booth, thrifty locals dug into their coats to produce faded Fl 10 bills and jingling coins.

The guilder sale was a “comical stunt” to take advantage of the commotion around the euro, said a spokeswoman for the safari park’s parent company, Libema. But the promotion also tapped into the Dutch public’s widespread disillusionment with the euro and nostalgia for their old currency.

Anti Chain Store Policies in India and America

When we think of growth and innovation we often think first of high-tech sectors but in the United States during the roaring 1990s it was retail productivity growth, led by Walmart, that drove the country. Retail productivity is important because the retail sector is huge and because retail productivity extends backwards to manufacturing and service productivity. Today, growth in India is slowing in part because the Indian government is no longer pushing reform, and the most notable failure is the failure to modernize India’s retail sector.

The Guardian: The beleaguered Indian government has been forced to suspend its decision to allow international supermarkets to invest in India‘s £300bn retail market in the face of political opposition.

…Allies of the increasingly vulnerable administration of Manmohan Singh, now in its second term, had refused to back the measure. Critics said the move, which theoretically does not need parliamentary approval, would put millions of shopkeepers across India out of business and threaten the livelihood of farmers.

Supporters argued that it would mean improvements of infrastructure and lower prices for consumers.

Analysts said the delay to the move was due to “political not ideological factors. There are local elections coming up and no one wants to risk the commercial traders’ votes…. The failure to implement what would have been the first major economic reform since Singh’s second term began in 2009 will reinforce the sense of drift surrounding the Indian government, compounding anxiety at a time when growth has slowed, inflation remains high and the value of the Indian rupee is dropping fast.

Stock prices of Indian retailers plunged in response to the news.

The political constraints here are enormous. Here is Marc Levinson author of The Box and more recently The Great A&P and the Struggle for Small Business in America, on some of the crazy anti-chain story policies in the United States:

President Franklin D. Roosevelt, who portrayed himself as the consumer’s friend, turned restrictions on chains into national policy. Under the National Industrial Recovery Act of 1933, one of Roosevelt’s programs to revive the economy, federally mandated codes were instituted that limited store hours, and regulated wages and prices — but the restrictions applied only to chains and large stores, not to mom-and-pop merchants. When those codes were invalidated by the Supreme Court, Congress enacted another law, the Robinson-Patman Act of 1936, intended to make most volume discounts illegal so that small shopkeepers could buy their goods for the same prices as giant chains.

In 1946, the government won criminal convictions against executives of the largest chain of all, the Great Atlantic & Pacific Tea Company (A&P), on the bizarre charge that they were violating antitrust law by selling groceries too cheaply. As late as 1953, the government was trying to break A&P apart by claiming that baking its own bread and canning its own vegetables gave the company an unfair advantage.
