Note: Estimates of standard errors in parentheses are robust to arbitrary forms of heteroskedasticity; clustered at community level (columns 1 –3) or individual level (columns 4 – 6). All models include flexible age controls and community fixed effects. Models in columns 4 through 6 also include survey wave and occupation fixed effects.
