Supplementary data for: Labor Supply and Household Dynamics

This project provides evidence that understanding household decisions and evaluating welfare-related policies requires incorporating an intertemporal dimension into collective household models. Unlike static models, intertemporal collective models account for the fact that most households consist of more than one decision maker whose preferences and constraints evolve over time. Using data from the Panel Study of Income Dynamics (PSID), the paper documents that gender differences in labor supply—particularly before and after marriage—do not emerge abruptly at the time of marriage, but instead develop gradually over time.
