Decoupled but Not Neutral: The Effects of Counter‐Cyclical Cash Transfers on Investment and Incomes in Rural Thailand
研究了泰国2009年对稻农实施的脱钩式价格保险计划，发现参与该计划增加了水稻产量，但导致投资和收入来源从农业转向非农活动，对农村发展可能有利。
In 2009, the Thai government implemented a price insurance scheme for rice, cassava, and maize farmers. The program, which was abandoned after only two years, added to the incomes of registered farmers a non‐negative but stochastic amount that was decoupled from farmers' agricultural activities. We apply a simple machine learning algorithm based on rich panel data to control for self‐selection into the program and study its impact on small‐scale rice farmers in relatively poor Northeastern Thailand. Program participation increases rice production but also leads to shifts in investment behavior and the composition of income generating activities away from agriculture, which may be beneficial for rural development. Moreover, farmers who are initially less poor experience a substantial increase in overall income. Decreasing risk‐aversion and relieved credit constraints may be possible channels for these effects.
