The Pass-Through of International Commodity Price Shocks to Producers’ Welfare: Evidence from Ethiopian Coffee Farmers
利用埃塞俄比亚家庭面板数据，研究发现国际咖啡价格下跌会显著降低以咖啡为生的农户消费，减少农业劳动供给（尤其是男性），并导致儿童营养不良。
Abstract International commodity price shocks may have large impacts on producers in developing countries. In this paper, a unique household panel data from Ethiopia is utilized to show that a decrease in international coffee price has strong pass-through to the consumption of households that rely on coffee production as a main source of livelihood. It also results in decreases in on-farm labor supply (particularly male labor supply) and induces reallocation of labor towards non-coffee fields, but has negligible effect on off-farm labor supply. The decline in consumption has significant consequences on child malnutrition: children born in coffee-producing households during low coffee price periods have lower weight-for-age and weight-for-height z-scores than their peers born in non-coffee households.
