Do rainfall conditions push or pull rural migrants: evidence from Malawi
利用马拉维2004/05年全国家庭调查数据，研究发现降雨冲击与农村向外迁移负相关，移民倾向于迁往降雨变异性低、干旱概率小的地区，且降雨冲击对近期移民消费的负面影响大于长期居民。
Abstract This article uses nationally representative data from Malawi's 2004/05 Integrated Household Survey (IHS2) to examine whether rainfall conditions influence a rural worker's decision to make a long‐term move to an urban or another rural area. Results of a Full Information Maximum Likelihood regression model reveal that (1) rainfall shocks have a negative association with rural out‐migration, (2) migrants choose to move to communities where rainfall variability and drought probability are lower, and (3) rainfall shocks have larger negative effects on the consumption of recent migrants than on the consumption of long‐time residents.
