Note: Standard deviations are in parentheses for means while heteroskedasticity robust standard errors are in parentheses for the tests of differences. Wild cluster bootrap p-values are in brackets.
Per-comparison significance: *** p<0.01,
**
p<0.05,
*
p<0.1.
Columns 1, 5, 9, and 13 show information for the non-attriters while Columns 2, 6, 10, and 14 show information for the attriters. Diff1 is coefficient in regression controlling only for participation at the later date. Diff2 is coefficient in regression aditionally controlling for village fixed effects. Income is in thousands of Guarani. All variables are measured in 2002.
