The Effect of Investment, LFA and Agri‐environmental Subsidies on the Components of Total Factor Productivity: The Case of Slovenian Farms
研究了2006-2013年间斯洛文尼亚农业中不同类型补贴对全要素生产率及其组成部分的影响，发现这些补贴对生产率没有显著作用。
Abstract The effect of subsidies on the performance of farms has received a great deal of attention in the literature, although results are inconclusive. Furthermore, much of the related literature examines the effect of subsidies only on technical efficiency (TE). We examine the effect of different types of subsidies on the different components of total factor productivity (TFP) in Slovenian agriculture over the period 2006–2013. We first estimate a Random Parameter Stochastic production frontier model. Then, based on the estimates of this model, we calculate and decompose the TFP index into TE, scale efficiency and technological change. Third, we apply combined difference‐in‐difference and a matching estimator to examine the effect of investment, less favoured area (LFA) and agri‐environmental (AE) subsidies on the different components of TFP. In our case, these subsidies are found to have no significant effect on either TFP or on its components.
