Source: PSID 1968-2009. The top panel reports results from models that include a quadratic in age, gender, marital status, race, the participation rate groups, the full set of area-by-year controls described in the text, interview year fixed effects, state of birth fixed effects, year of birth fixed effects, and interactions of the predicted participation rate and state, cohort, and interview year fixed effects. The bottom panel reports results after removing the demographic controls, and area-by-year controls. See text for an explanation of the analytical sample and construction of the outcome variables. All estimates are weighted and standard errors are clustered on state of birth.
