A little digging reveals that the American public health profession’s academic journals seem to be filled with articles on time preference and all kinds of diseases and ailments. I know that the Johns Hopkins School of Public Health, which is the top school in the field, requires a course or two in economics. Here’s one article:
“Obesity and the Rate of Time Preference,” by Joh Komlos (Univ. of Munich), Patricia Smith (Univ. of Michigan), and Barry Gogin (Univ. of Michigan).
Another is an NBER Working Paper entitled “Why Do Dancers Smoke? Smoking, Time Preference, and Wage Dynamics,” by Lalith Munasinghe and Nachum Sicherman (Columbia Univ.). “Smokers compared to their non-smoker counterparts earn lower wages at the time when they first enter the labor market and experience substantially lower rates of wage growth . . . . These diferences . . . are consistent with our time preference hypothesis . . .”
