Who are the most partisan columnists?

Lyinginponds.com provides a running tab on which media writers toe a particular political line. The “winners” for the Total Partisanship Index are the following individuals, with 100 on the scale meaning pure partisanship:

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

The numbers try to measure how much the writer sides with one political party rather than the other. Click on the links for full explanations of the various indices.

Are student evaluations a good idea?

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.

Global warming update

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.

Do scientists know what makes you happy?

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.”

Do you know what makes you happy?

“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.

The mind of Paul Krugman

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.

Restaurant economics

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.

Blogging for profit?

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.

Induced innovation in prisons

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.

Will Vouchers Split the Democratic Party?

The debate so far Tyler 1, Alex 1, Tyler 2.

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.

Long Live the Marginal Revolution!

It looks like our short-lived technical difficulties are over (cross fingers!). If all continues to be well we should now be available at our permanent address, www.MarginalRevolution.com which is easier to remember than http://MarginalRevolution.blogs.com (the old address will continue to work just fine of course as they map to the same place). I have a question for the techies. Do different browsers use different DNS servers? I was very puzzled to find that the new address worked from IE at least several minutes earlier (and perhaps longer) than from Mozilla. Email me if you know the answer.

Can you find a Republican on the MIT faculty?

I am not a Republican, but the results from articles of this kind, from David Horowitz’s Center for the Study of Popular Culture, disturb me. In America the number of registered Democrats and Republicans, over time, is roughly equal. The same cannot be said for university faculty. The most Republican school these researchers had in their sample was Northwestern, which still had a 4-1 ratio in favor of Democrats. The aggregate ratio was about 10-1, with the school sample included the entire Ivy League and Berkeley. Brown had a 30-1 ratio in favor of the Democrats. They couldn’t find a registered Republican at MIT, Williams, Oberlin, or Haverford. They found 3 registered Republicans among the administrators of the Ivy League.

Being a collector is cheaper than you think

“…80 percent of the lots Christie’s sell go for under $8,000.” From the Thursday New York Times (registration required), and why couldn’t an editor improve the grammar in that sentence? The median lot at Sotheby’s sells for $4,177, at Christie’s South Kensington, a branch, the median lot sells for $2,259. More than ever before, collecting is no longer the exclusive province of the wealthy.

Why I worry about vouchers

Alex (my co-blogger) and I have been arguing for years, it is perhaps no surprise that now we do it in the blogosphere. He is more optimistic about the performance of school vouchers than I am. He notes that housing vouchers have worked well, better than government housing, I think that school vouchers are more problematic than housing vouchers for several reasons:

First, government must define which schools are acceptable recipient of vouchers. In the short run it is fairly clear, it is far less so if we have vouchers in place for twenty years and schooling evolves. What about schools that teach black supremacy? Radical Islam? Creationism? Remember how controversial a few supposedly obscene NEA grants were? Not all those grants went directly to the artists either. What if an educational program involves home schooling plus ten hours of class time a week? Would that qualify for a voucher? Defining “suitable housing” does not involve a problem of nearly this magnitude.

Second, school vouchers could become the new middle class entitlement, as I mentioned in my New Zealand post earlier today. Imagine politicians upping the voucher amount and coverage to win votes each election cycle, just as they are now extending senior health coverage to prescription drugs. Again, we have not seen this with housing vouchers but “parents” are a much bigger and stronger constituency.

If I had my finger on the vouchers button, I would press it and allow experimentation at the state and local levels. So many American urban public schools are a disgrace. But few partial deregulations have worked better than promised. Most have created perverse incentives and occasioned considerable backlash, we all know that electricity “deregulation” has been a mixed bag at best, although the idea in principle makes sense.

If we are going to move forward with vouchers, I would like to know what the plan will look like, once it gets through the political meatgrinder. I don’t know any voucher proponent who has done this.

How rich are you, globally?

If you earn $36,000 per year, you are in the top one percent of our planet, for a more comprehensive look at your relative status, check out the Global Rich List, don’t use commas when you type in your yearly income. Their stated goal is to encourage charity and make us feel happy about how rich we are, in reality I think they are trying to make us feel guilty about how rich we are. They don’t mention the policies and cultural attitudes that created this wealth.

The reference is from the blog of John M Scalzi.

Addendum: Donald Sensing tells us much more about the genesis and meaning of the list.
