The Impact of Direct Income Transfers of CAP on Greek Olive Farms’ Performance: Using a Non-Monotonic Inefficiency Effects Model
研究了欧盟直接收入补贴对希腊橄榄农场技术效率的影响，发现补贴有单调负效应，而专业化程度有非单调效应。
We analyse the impacts of direct income transfers on the technical efficiency of Greek olive farms. We use a production frontier function and a non-monotonic inefficiency effects model, which incorporates the influences of exogenous variables (subsidies, farm characteristics, etc.) on technical efficiency. The model is applied to 1995–2004 FADN data. The results show that direct transfers of the CAP had a negative and monotonic effect on technical efficiency, whereas the degree of specialisation had a non-monotonic effect on technical efficiency.
