Air Pollution and Procyclical Mortality

Authors: Christopher J. Ruhm, Garth Heutel

Prior research demonstrates that mortality rates increase during economic booms and decrease during economic busts, but little is known about the role of environmental risks as a potential mechanism for this relationship. We investigate the contribution of air pollution to the procyclicality of deaths by combining county-level data on overall, cause-specific, and age-specific mortality rates with county-level measures of ambient concentrations of three types of pollutants and the unemployment rate.

The Effects of California's Paid Family Leave Program on Mothers' Leave-Taking and Subsequent Labor Market Outcomes

Authors: Christopher J. Ruhm, Maya Rossin-Slater, Jane Waldfogel

This analysis uses March Current Population Survey data from 1999-2010 and a differences-in-differences approach to examine how California’s first in the nation paid family leave (PFL) program affected leave-taking by mothers following childbirth, as well as subsequent labor market outcomes. We obtain robust evidence that the California program more than doubled the overall use of maternity leave, increasing it from around three to six or seven weeks for the typical new mother – with particularly large growth for less advantaged groups.

Understanding Overeating and Obesity

Authors: Christopher J. Ruhm

The combination of economic and biological factors is likely to result in overeating, in the current environment of cheap and readily available food. This propensity is shown using a “dual-decision” approach where choices reflect the interaction between two parts of the brain: a “deliberative” system, operating as in standard economic models, and an “affective” system that responds rapidly to stimuli without considering long-term consequences.
