On another note, one of the puzzling underlying findings in this paper is the relationship between moderate alcohol consumption and increased lifetime earnings. For men and women alike, people who report downing two or fewer drinks a day earn slightly more than teetotalers do, on average. Heavy alcohol use tends to negatively impact earnings, as you might imagine, but not as much as abstinence. Sloan and Ostermann aren’t clear on the mechanics of this relationship, but the science seems solid.

Does drinking lead to higher earnings, or vice versa?
