Migration is a common means of adaptation to weather shocks. Previous research has identified heterogeneous effects according to age, sex, and wealth, but little is still known about how marriage-related institutions affect such migration. Relying on a quasi-experimental identification strategy, we analyze marriage- and work-related migration in Malawi following large droughts, separating the effects for female and male migrants according to different age groups. The analysis based on stated motives of migration reveals marginal decreases in marriage-related migration among girls, but increases in marriage-related migration within districts for women in older age groups. We also find large increases in work-related between-district migration for boys, and to a smaller extent also for girls following severe drought. The results add to the evidence of the potentially adverse effects of migration as a coping mechanism following drought when other means of insurance do not exist.

马拉维干旱的性别移民反应

迁移是适应天气冲击的常用手段。以前的研究已经根据年龄、性别和财富确定了异质性影响，但对于与婚姻相关的制度如何影响这种迁移仍然知之甚少。依靠准实验识别策略，我们分析了大旱后马拉维与婚姻和工作相关的移民，根据不同年龄组区分了女性和男性移民的影响。基于所述迁移动机的分析显示，女孩中与婚姻有关的迁移略有减少，但在地区内，老年组妇女中与婚姻有关的迁移有所增加。我们还发现，男孩与工作相关的跨区迁移大幅增加，严重干旱后女孩的迁移幅度也较小。
