We investigate the relationship between physical attractiveness and the time people devote to video/computer gaming. Average American teenagers spend 2.6% of their waking hours gaming, while for adults this figure is 2.7%. Using the American Add Health Study, we show that adults who are better-looking have more close friends. Arguably, gaming is costlier for them, […] The post Video games and looks appeared first...

Exchange-rate models fit very well for the U.S. dollar in the 21st century. A “standard” model that includes real interest rates and a measure of expected inflation for the U.S. and the foreign country, the U.S. comprehensive trade balance, and measures of global risk and liquidity demand is well-supported in the data for the U.S. […] The post Finally, exchange rate models seem to...

Teamwork has become more important in recent decades. We show that larger teams generate an unintended side effect: individuals who finish their PhD when the average team in their field is larger have worse career prospects. Our analysis combines data on career outcomes from the Survey of Doctorate Recipients with publication data that measures team […] The post Beware research in large teams appeared...

That is the (very good) title they gave my recent Bloomberg column.  Should Europe have more air conditioning?  Basically yes.  Here is one excerpt: Some 90% of the US has air conditioning, according to one estimate, compared to only 19% for Europe. Worldwide, the US, China and Japan account for about two-thirds of all air conditioning… […] The post Europeans deserve to be as cool...

Adjusting for inflation, President Biden is one of the lowest-paid Presidents in American history. See the first and last figures in this analysis from 2012. This source’s figures are all in 2012 dollars, and there’s been 39% cumulative inflation since then, while the President’s nominal salary has stayed fixed at $400,000/year (nominal). So Bill Clinton’s average […] The post The pay of Presidents (from my...

In July 1946, 20-year-old Helen Hutchison walked into the Vanderbilt University prenatal clinic in Nashville, Tennessee. Helen found herself pregnant after her husband had returned from combat in World War II. The pregnancy, however, had not been easy. During her visit to the clinic Helen’s doctor handed her a small drink. “What is it?” she […] The post US Human Experimentation Without Consent or...

Some 40 per cent of the biggest US manufacturing investments announced in the first year of Joe Biden’s flagship industrial and climate policies have been delayed or paused, according to a Financial Times investigation.

1. August Strindberg, The People of Hemsö.  Hardly anyone (non-Swedish?) reads this classic novel any more, but it holds up as one of the more compelling creations of its time.  Direct and compelling.  Swedish people on an island, but will this marriage work?  Why has it so faded from our attentions?  I’ve long loved Strindberg, […] The post What I’ve been reading, or not...

For the United States, might it be a suburb of Columbus, Ohio?  Or perhaps Knoxville, Tennessee, which is not too far from the country’s population center? Those locales are relatively generic, and not too much of any single region, or perhaps they straddle regions.  They represent life in the United States as a whole, unlike […] The post The most typical place in each...

That is the topic of my latest Bloomberg column, and here is one excerpt: What do the numbers show?

When I travel abroad, I will often get recommendations of where to eat, what to do and what to read and watch from Sam Mendelsohn. Not just a few sentences, as if from a travel guide, but pages of unique and original material.

Of course the crypto prices fell first, over the weekend.  I think Bitcoin fell by about 15 percent? You can think of crypto as a hedge against illiquidity, rather than against inflation, or against the decline of America, or whatever.  There are not enough liquid assets!  So sometimes solvent economies go tails up, because debtors […] The post I think crypto performed well in...

From Steve Landsburg in the WSJ: Here’s an economics brain teaser: Apples are provided by a competitive industry. Pears are provided by a monopolist. Coincidentally, they sell at the same price. You’re hungry and would be equally happy with an apple or a pear. If you care about conserving societal resources, which should you buy? […] The post What aspiring economists aren’t being taught...
