The unit of analysis is a partition of a language group. Standard errors in parenthesis clustered at the language group level. All columns are estimated by maximum-likelihood Probit models.

The coefficients report the change in the probability of the dependent variable induced by a change in the respective regressor. In (1) and (2) the dep. var. is an indicator that takes the value 1 if pasture dominates land use in the partition. In (3) and (4) the dep. var. is an indicator that takes the value 1 if maize is the dominant crop in the partition. In (5) and (6) the dep. var is an indicator that takes the value 1 if sorghum is the dominant crop in the partition. See web Appendix for variable’s definitions.
