Subsidies and agricultural productivity in the EU
利用2004-2014年213个欧盟地区面板数据，发现欧盟共同农业政策补贴总体上提升了农业劳动生产率，但不同类型补贴效果相反：脱钩补贴促进增长，而挂钩补贴则减缓增长。
Abstract This paper investigates the relationship between EU agricultural subsidies and agricultural labor productivity growth by estimating a conditional convergence growth model. We use more representative subsidy indicators and a wider coverage (panel data from 213 EU regions over the period 2004–2014) than have been used before. We find that, on average, EU's Common Agricultural Policy (CAP) subsidies increase agricultural labor productivity growth, but this aggregate effect hides important heterogeneity of effects of different types of subsidies. The positive effect on productivity comes from decoupled subsidies, that is, Pillar I decoupled payments and some Pillar II payments. Coupled Pillar I subsidies have the opposite effect: they slow down productivity growth.
