Abstract

This paper explores an empirical methodology to assess the impacts of trade reforms on household behavior in developing countries. It focuses on consumption and income responses: when price reforms take place, households modify consumption and production decisions and local labor markets adjust. The paper proposes a joint estimator of demand and wage price elasticities from survey data. The method uses an empirical model of demand to extract price information from unit values, and uses this information to estimate the response of households to price reforms. By correcting unit values for quality effects and measurement error, the method overcomes the problem of the endogeneity of unit values. By endogeneizing household income, the model corrects potential biases in the estimation of own- and cross-price elasticities in consumption. The paper applies the method to an expenditure and income survey for rural Mexico. It shows that the corrections suggested in this paper are empirically important. In particular, it shows that allowing for consumption and income responses is a key element of an accurate empirical assessment of trade policy.
