There are active plans to translate the new Harry Potter novel into ancient Greek and Latin. They are still looking for a translator for the ancient Greek edition, which is intended as an learning aid. The stories have sold 120 million copies worldwide, in 40 languages.
Nobel Laureate Daniel Kahneman is engaged in some fascinating work, read this summary:
“…the duration of an experience plays essentially no role when evaluating how well it becomes etched in our memories.
Kahneman believes the most direct way to evaluate experienced utility is to ask people how they feel at a certain moment, a notion he calls “moment utility.”…But because researchers are more interested in extended outcomes, more often the question they ask is memory-based: “How was it?” Kahneman said this is a different question that reflects the individual’s global evaluation of an entire episode in the past and it may not be a direct assessment of the individual’s real-time state. This “remembered utility,” said Kahneman, is not a very good guide when predicting outcomes. The “total utility” of a state is derived from the moment-based approach of measuring the real time pleasure or pain experienced by the individual.”
In other words, one of our selves does the living, another keeps the memories.
“”When people make decisions, the remembering self is in control, Kahneman explained. “We make our decisions in terms of our memories and basically, we maximize remembered utility, not the actual total utility,” he said. “The only thing we can learn to maximize through personal experience is remembered utility.””
And don’t you forget that.
Steve Levitt, recenty profiled in the NYT Magazine has written another amazing and sure to be controversial paper. Levitt and co-author Roland Fryer begin The Causes and Consequences of Black Names with some startling statistics on the racial divide in names. For example, “more than forty percent of Black girls born in California in recent years received a name that not one of the roughly 100,000 white girls born in California in that year was given.” Blacks are more segregated by name than are other races – the majority of Asians, for example, choose from the same name-pool as do whites. Segregation by naming has also increased over time. Prior to the late 1960s, for example, blacks and whites chose from the same name-pool to much greater degree than they do today.
Other studies have shown that when sent resumes identical but for name, employers more frequently ask for follow-up interviews with applicants who have stereotypical white names. Levitt and Fryer respond to these studies in two ways. The first response I find unconvincing. They argue that it is unlikely that a black name could have a big impact on earnings because “Once an employer has met a candidate in person, race is directly observable. A person’s manner of speaking, dress, interview responses and on-the-job performance no doubt provide far better signals of productivity than a name.” No doubt – but this is a rather facile interpretation of the audit studies. The point of these studies was not the literal one that employers discriminate on the basis of a person’s name! The point is that if employers use names to discriminate on race at the resume stage then they probably discriminate on race at every other stage in ways that are harder to identify.
Levitt and Fry have a more convincing but sure to be controversial response to this larger issue. They find that black names signal a variety of other characteristics that could plausibly be connected with lower labor productivity. Here is a key quote:
a woman with a BNI equal to one (implying a name that no Whites have) is 10 percentage points more likely to have been born to a teenage mother and 9 percentage points more likely to have been born out-of-wedlock than a Black woman living in the same zip code with the same age and education, but carrying a name that is equally common among White and Blacks. The woman with a Black name is also more likely to have been born in a Black neighborhood and to herself be unmarried.
In other words, names carry information even after the typical information available on a resume has been taken into account and the information that especially black names carry plausibly suggests lower productivity. It’s papers like this that explain why professors need tenure.

Ann Coulter – 77
Paul Krugman – 74
Robert Scheer – 72
Molly Ivins – 68
Frank Rich – 61

Here is Michael Huemer’s very interesting critique of student evaluations of professors, full of cites and links. Yes, student evaluations correlate positively with other measures of teaching effectiveness. Take multiple sections of the same course and give a common final exam, the correlation is in the neighborhood of 0.4 to 0.5.
On the other hand, a professor gets a much better evaluations if students think they will get good grades. The statistical correlations are strong and hard to deny. And in one study 70 percent of students admitted that their evaluation was influenced by the grade they expected to get. See this game theory article on how one-shot reciprocity can work.
In one survey, 38 percent of professors admitted to dumbing down their courses to get better evaluations.
Cosmetic factors such as appearance have a big influence on evaluations.
Huemer offers no policy conclusion. He does note that ratings by colleagues and other observers do not agree with each other very much and thus cannot stand as a serious alternative.
If you are curious, I could not find Huemer’s student evaluations through a web search.
Fungi under the snow may contribute significantly to CO2 levels, according to this Washington Post article (brief registration required). Here is one bit:
“We’re living in a world where global warming is a constant threat, but in fact we have relatively little knowledge of what the inputs and outputs are for CO2.” said Steven Miller, a mycologist, or fungus specialist, at the University of Wyoming.”
Here is another:
“…global warming models can no longer ignore fungi in snowy regions and seasons as they have, scientists said – especially because about 40 percent of Earth’s landmass is covered with snow for at least part of the year.”
I am not one of those economists who wishes that global warming would go away, and simply assumes that science is on my side, or reads the evidence selectively. And of course items such as this can be cause for either optimism or pessimism, what if fungi under the snow contribute to a crisis rather than easing it? Still, Bush was not crazy to refuse to go along with Kyoto.
Tyler disagrees (see his entry below for more information) with Loewenstein on the implications of happiness research. It’s evident that the key figures also come to different conclusions on even simple policy questions. Consider the following quotes from the NYT Magazine article (written by Jon Gertner):
One experiment of Gilbert’s had students in a photography class at Harvard choose two favorite pictures from among those they had just taken and then relinquish one to the teacher. Some students were told their choices were permanent; others were told they could exchange their prints after several days. As it turned out, those who had time to change their minds were less pleased with their decisions than those whose choices were irrevocable.
Yet just a few pages we are told that Daniel Kahneman, recent Nobel prize winner and another key player in this field, “sees a role for affective forecasting on consumer spending where a ‘cooling off’ period might remedy buyer’s remorse.”
“You are wrong to believe that a new kitchen will make you happy for as long as you imagine.”
Conversely, a tense marriage or a trick knee will give you more agony than you think. But most things matter less than we think they will, an old theme from the seventeenth century French moralist La Rochefoucauld. There is a good deal of experimental evidence that we make these “happiness mistakes” time and again, failing to learn from experience.
So argues Daniel Gilbert, professor of psychology at Harvard, profiled in today’s New York Times Magazine (registration required). Daniel Kahneman, last year’s Nobel Laureate in economics (with Vernon Smith), once told me that time spent with friends, not new gadgets, is what people really enjoy.
Our brains are trying to regulate our behavior, not trying to make us happy. According to Tim Wilson,
“We don’t realize how quickly we will adapt to a pleasurable event and make it the backdrop of our lives. When any event occurs to use, we make it ordinary. And through becoming ordinary, we lose our pleasure.”
We systematically fail to realize how powerful our psychological defenses are, once those defenses become activated. But Gilbert suggests we might need these carrots and sticks to get things done, even if they are illusions.
George Loewenstein, an economist at Carnegie-Mellon, says
“…he [Loewenstein] doesn’t see how anybody could study happiness and not find himself leaning left politically; the data make it all too clear that boosting the living standards of those already comfortable, such as through lower taxes, does little to improve their levels of well-being, whereas raising the living standards of the impoverished makes an enormous difference.”
I buy the basic claims about happiness, but dispute the political conclusion. To the extent we should care about happiness, our imperative is to boost the rate of economic growth, strengthen Western civilization, and hope that Western-style institutions spread around the world. All of these mean a heavy reliance on markets, incentives, and the rule of law.
Here is an interview with Paul Krugman, talking for the left-wing audience of LiberalOasis and thus, believe it or not, less restrained than usual. Here is one revealing bit, talking about the United States post-9/11: “I felt for a little while there like I was all alone, [that] they’re all mad but me.”
He also uses the phrase “My finest hour” is a non-ironic way, when speaking of the California energy crisis.
He talks about his new book The Great Unraveling: Losing Our Way in the New Century as well. I will offer some comments once my copy arrives.
It has long been a puzzle why certain commodities receive a higher “mark-up” than others. Why is popcorn so expensive at the movie theater? Why is wine so expensive in fine restaurants?
Daniel Boulud, one of New York’s leading chefs (Daniel, Cafe Boulud, and DB Bistro Moderne), addresses this question in his recent memoir Letters to a Young Chef. Boulud tells us that wines make up 30 percent of revenue in his restaurants and have a mark-up of two to three hundred percent.
John Lott and Russ Roberts (yes, that is the John Lott) once raised the possibility that a high drinks price is a way of charging those people who wish to linger at the table longer. Boulud offers another explanation based on price discrimination. He (p.62) claims that drinkers of fine wine are “a great clientele,” and are “willing to indulge.” They will expect “only the finest ingredients,” such as good truffles, and are willing to pay for them. By offering these people fancy wines at high prices, you induce them to pay a higher net price for their meal. At the same time you need some acceptable, cheaper wines: “Those [other] customers are your future and you cannot afford to drive them away with the sticker shock of a Greatest Hits wine list.”
Boulud also claims that good restaurants are well-situated to invest profitably in wine, thus the special importance of wine for revenue.
The book contains many kinds of advice. Keep your knives sharp, we are told, and if you want to make other chefs happy, serve them a pig’s head, not caviar.
Companies used to fire their employee bloggers. Now some of them are discovering that blogging is the “ultimate customer intimacy tool.” Imagine chatting with your customers on a regular basis, telling them what the product means for their lives, informing them of new developments, and having them visit you [your site] every day. Who knows, it might even supplant some telemarketing. Here is the link. And see this recent discussion of how blog names matter and signal the nature of content.
This fascinating article from Wired illustrates how prisoners make the best of their environments by inventing new contraptions.
“Locked in a California prison, Angelo needs a cup of coffee. Bad. But electric heaters used to make instant joe are contraband in jail. So his cellmate combines the metal tabs from a notebook binder with a couple of melted toothbrushes and some rubber bands.
Soon, Angelo is sipping Folgers.
The jury-rigged heater is one of nearly 80 improvised items Angelo meticulously diagrams in a new book, Prisoners’ Inventions [check out this fascinating link, which offers diagrams of the inventions and further description]. Working with the Chicago-based art group Temporary Services, Angelo (not his real name) shows how inmates fashion dice from sugar water and toilet paper, dry bologna jerky on jail-house light fixtures, turn hot sauce bottles into shower heads and make grilled cheese sandwiches on prison desks.”
One individual from Temporary Services notes that in the movies, “prisoners only create things to escape, get high or kill each other.”
The whole thing reminds me of Soviet engineers.
Let me take Tyler’s weakest point first. He writes, “Imagine politicians upping the voucher amount and coverage to win votes each election cycle…” What like education spending is not a political issue today? In fact, over the past several decades we have doubled real per-capita spending on schooling with zero increase in productivity. It’s possible that government would set an education voucher at too high an amount (but let’s get it above zero before we worry about this!) but at least we will get something for our money.
Defining an acceptable school is a legitimate issue but one that we already face today with private schools, charter schools, and home schooling. I see no reason why private schools under a voucher system could not be regulated as private schools are today. Private schools do face some minimal regulations including hours and some content requirements but I don’t think these have been a significant constraint. Some private schools will undoubtedly teach nonsense but Tyler seems to forget that Ebonics, to give just one example, was a creature of the public schools not the private schools.
I will agree, however, that current voucher plans are typically terrible. Existing vouchers are often limited to poor students and sometimes just to poor students in “failing” schools, the voucher amounts are typically low and to add insult to injury it is often illegal to add-on to the voucher amount (a type of price control). Finally, nowhere near enough students are suported. The DC plan, for example, is aimed at some 2,000 students in a school system of 66,000.
I recommend John Merrifield’s School Choices: True and False as an antidote to this kind of limited thinking. Merrifield’s bottom line is that we need a system under which the government in no way discriminate against parents who send their children to private schools.
