On the Joint Consumption and Labour Supply Effects of Migration on those Left Behind
研究了迁移对留守家庭成员消费和劳动供给的联合影响，提出新框架评估福利效应，发现考虑休闲成本后迁移的净福利增益比仅看消费增益减少四分之一。
Previous literature has investigated the effect of migration on remaining household members’ consumption or labour supply, but has rarely examined them jointly. When migration increases consumption but reduces leisure time, one needs a specific framework to draw a conclusion about the overall impact on welfare. I propose such a new approach and test its theoretical implications using household panel data from rural Mexico. The results reveal that adjusting for leisure costs reduces the net welfare gain of migration by one fourth relative to what the consumption gain would suggest.
