摘要

在这项对2007年至2016年瑞典农场的研究中，我们估计了共同农业政策的投资支持对农场绩效指标的影响，重点是长期影响。为了隔离影响并缓解选择偏差的问题，我们采用了反事实的经验设计，使用了粗化精确匹配和动态面板固定效应估计。经处理的估计数的平均处理效果表明，在生产力和营业额方面，农场表现有了积极而显著的长期改善。然而，研究结果表明，投资和累积的可观察效应之间存在显著的时间滞后，因为我们发现补贴的大多数短期效应是微不足道的。

Assessing long-term effects of CAP investment support on indicators of farm performance

In this study of Swedish farms from 2007 to 2016, we estimate the effects of investment support from the Common Agricultural Policy on indicators of farm performance, focusing on long-term effects. To isolate the impact and alleviate problems of selection bias, we employ a counterfactual empirical design using Coarsened Exact Matching and dynamic panel fixed-effects estimations. The average treatment effect on the treated estimates show a positive and significant long-term improvement of farm performance with regard to productivity and turnover. However, the results indicate significant time lags between investments and accumulated observable effects, as we find most short-term effects of the subsidy to be insignificant.
