  • Coefficients are marginal effects. For dummy variables, the marginal effect refers to effect of discrete change in the dummy variable from 0 to 1. The z statistics of the coefficients are in parentheses. Omitted categories include male gender, illiterate, owner farmers (occupation), the time effect of wave 1 and rural area of residence. The reduced form estimate of the price equation is reported in online appendix in table A2.
