Does access to off-farm income complement or compete with agricultural production? This article explores the effect of off-farm income on agricultural production activities, using data from the 2003 Mexico National Rural Household Survey. We first discuss the theoretical conditions under which access to off-farm income may influence production in an agricultural household model. Instrumental-variable (IV) estimation methods are then used to test whether agricultural production activities, technologies, and input use differ between households with and without access to off-farm income. We find that off-farm income has a negative effect on agricultural output and the use of family labor on the farm, but a positive impact on the demand for purchased inputs. There is also a slight efficiency gain in households with access to off-farm income. Findings offer insights into how household production evolves as rural households increasingly engage in off-farm income activities.

The migration of labour out of rural areas and the flow of remittances from migrants to rural households are an increasingly important feature of less developed countries. This paper explores ways in which migration influences incomes and productivity of land and human capital in rural households over time, using new household survey data from Mexico. Our findings suggest that a massive increase in migration to the United States increased per-capita incomes via remittances and also by raising land productivity in migrant-sending households. They do not support the pessimistic view that migration discourages production in migrant-sending economies, nor the view implicit in separable agricultural household models that migration and remittances influence household incomes but not production.
This article describes a user-written command, descogini, that decomposes the Gini coefficient by income source and allows the calculation of the impact that a marginal change in a particular income source will have on inequality. descogini can be used with bootstrap to obtain standard errors and confidence intervals.
