Determinants of Migration: Cotton Strikes and Income Shocks in Mali
研究了马里棉花罢工导致的暂时性收入损失如何影响农业家庭的迁移决策，发现收入下降使家庭迁移率在六年内降低约32%，表明缺乏现金是贫困人口迁移的制约因素。
How do transitory income shocks affect household migration decisions in low-income countries? We study how income losses from a cotton strike affecting Malian districts differentially changed agricultural household migration choices. The short duration and geographic specificity of the strike allows us to cleanly identify the long-run impact of a sudden change in household income on migration choices. We show that a drop in income precipitated by the strike reduced household migration rates by approximately 32% over a six-year period. A randomized inference placebo test corroborates the validity of our result. We demonstrate that not having cash on hand is a binding constraint to labor migration for poor populations.
