本文利用世界银行数据库“农业激励措施的扭曲”，分析了1990 - 2010年期间农业激励措施对各国粮食安全的影响。我们采用了一种连续的治疗方法，应用广义倾向评分匹配，以减少潜在的偏见所观察到的国家特征的差异。研究结果提供了强有力的证据，自我选择和异质性粮食安全的影响，在不同水平的政策强度。对剂量反应函数的估计表明，对农业的歧视和对农业的大力支持导致粮食安全的可获得性、可获得性和利用方面的表现不佳。JEL代码：C21、F14、F60、O 50、Q17。
Abstract Using the World Bank database “Distortions to agricultural incentives,” this paper analyzes the impact that agricultural (dis)incentives have on food security for a wide sample of countries over the 1990‐2010 period. We adopt a continuous treatment approach applying generalized propensity score matching to reduce potential biases stemming from differences in observed country characteristics. The results provide strong evidence of self‐selection and heterogeneous food security impacts at different levels of policy intensity. Estimates of the dose‐response functions show that both discrimination against agriculture and large support for it lead to poor performance in the availability, access, and utilization dimensions of food security.
