英文文献作者：Ortega-Sanchez, Ismael R.,Findeis, Jill L.
英文文献摘要：
Farm productivity in agrarian economies is frequently and considerably altered by the outmigration of household labor. Using household survey data we examine labor outmigration impact on corn farmers of the central and south regions of Mexico. Specifically, comparative changes in labor productivity are estimated in a sequential production technology specification with nonlinear components in the context of different agricultural environments.
