出稼ぎが、医療費と子供の栄養状態におよぼす影響について -CSES 2009 を用いた計量分析-

Abstract

This study aims to investigate the effects of migration on child health and nutrition in rural Cambodia, where emigration has been increasing rapidly. If we estimate these impacts by simultaneously using a migration variable and a variable of remittance from migrant, we potentially face with problems of endogeneity, selection bias, and/or multicollinearity. To address these problems, we estimate the impacts of migration and remittance by applying a two-stage least squares(2SLS) modeling analysis on 2009 data obtained from the Cambodia Socio-Economic Survey(CSES). The estimation results show that the impact of migration and remittances on child nutrition are insignificant. However, their impacts on household expenditure for nutrition are significantly positive.
