Note: All regressions include year and region fixed effects, log wage, food ratio, demographic (age, completed years of education, a good health status indicator, household non-labor income, number of children, and a recent pregnancy indicator) and spousal characteristics (age, completed years of education, a good health status indicator, and log wage). In addition, husband’s (wife’s) regression includes a husband’s (wife’s) sedentary-job type indicator. Conventional distribution factors: spouses’ wage ratio, their age ratio, and their years of education ratio. Standard errors are reported in parentheses. Bootstrapped standard errors clustered at the age-education-region level (136 groups) based on 300 replications are reported in brackets.
