In the paper, Betsey Stevenson and Justin Wolfers argue that money indeed tends to bring happiness, even if it doesn’t guarantee it. They point out that in the 34 years since Mr. Easterlin published his paper, an explosion of public opinion surveys has allowed for a better look at the question. “The central message,” Ms. Stevenson said, “is that income does matter.”

To see what they mean, take a look at the map that accompanies this column. It’s based on Gallup polls done around the world, and it clearly shows that life satisfaction is highest in the richest countries. The residents of these countries seem to understand that they have it pretty good, whether or not they own an iPod Touch.

If anything, Ms. Stevenson and Mr. Wolfers say, absolute income seems to matter more than relative income. In the United States, about 90 percent of people in households making at least $250,000 a year called themselves “very happy” in a recent Gallup Poll. In households with income below $30,000, only 42 percent of people gave that answer. But the international polling data suggests that the under-$30,000 crowd might not be happier if they lived in a poorer country.
