| Technical efficiency and its determinants among organic and conventional farms in Sweden are analyzed for time-period 2000-2002. In addition, we address the issues that arise when comparing performance measures among the two groups of producers (conventional and organic) due differences in their technologies and the potential presence of self-selection in the farmer's choice of using conventional or organic production methods. If the choice of production method is based on, or at least in part based on, the farms expected productivity in organic and conventional farming respectively there is self-selection present that must be considered. We apply an endogenous switching regression model suggested by Lee (1978) to compare efficiency measures between the... |

| This article deals with the optimal differentiation of agri-environmental contracts based on a self-selection mechanism. The paper demonstrates that both economic efficiency and effectiveness of public expenditures can be increased, if a menu of combinations of farming practices and payments are offered. However, there is a trade-off between efficiency and effectiveness, since the optimal programme minimising government expenses does not simultaneously minimise farmers’ opportunity costs. A numerical example of differentiated agri-environmental contracts, aiming for the reduction of nitrogen fertiliser in wheat production, illustrates that efficiency and effectiveness gains can be substantial. Furthermore, it is shown that economic rents for agricultural... |
