Do Subsidies Drive Productivity? A Cross-Country Analysis of Nordic Dairy Farms

One of the foremost objectives of the Common Agricultural Policy (CAP) in the European Union (EU) is to increase agricultural productivity through subsidization of farmers. However, little empirical research has been done to examine the effect of subsidies on farm performance and, in particular, the channels through which subsidies a®ect productivity. Using a Bayesian hierarchical model in which input productivity, efficiency change and technical change depend on subsidies and other factors, including farm location, we analyze empirically how subsidies affect the performance of farms. We use an unbalanced panel from the EU's Farm Accountancy Data Network on Danish, Finnish and Swedish dairy farms and partition the data into 8 regions. The data set covers the period 1997 to 2003 and has a total of 6609 observations. The results suggest that subsidies drive productivity through efficiency and input productivities and the magnitudes of these effects differ across regions. In contrast to existing studies, we find that subsidies have a positive impact on technical efficiency. The contribution of subsidies to output is largest for dairy farms in Denmark and Southern, Central and Northern Sweden
