The study evaluates the efficiency of government intervention using a vertical structured model including imperfectly competitive agricultural input markets, the bread grain market, and the imperfectly competitive food industry. To test for policy efficiency the actually observed bread grain...

This study presents a general model demonstrating how to measure the (in)efficiency of a policy intended to meet objectives. If it is assumed that the government has available only those policy instruments it actually utilizes, our method is a test as to whether the government combines these...

Governments in developed countries aim to increase the market share of organic products as a possibility to improve the environment or animal welfare or as a reaction to food crises and changing consumer preferences. Assuming that organic farming creates a positive externality, we address the...

In developed countries governments aim to increase the market share of organic products. Assuming that organic farming creates a positive externality, we address the question of how this environmental benefit can be internalized best. Using the concept of heterogeneous producers and consumers we...

Based on a graphical model we analyse the impacts of the Fischler Reform on land prices and the capitalization of single farm payments (sfp) into land values. The model shows that if there are more sfp than eligible land, the capitalization ratio will not decline but rather increase due to the...

By definition agri-environmental programs of the EU aim not only at improving environmental quality, but also at reducing overproduction while supporting farm income. The aim of the study is to empirically measure the success of agri-environmental programs in regard to the objective of reducing...

Recent studies have investigated the efficiencies of policies that use several policy instruments simultaneously (for example, a policy that uses a production subsidy combined with a production quota). Several studies of very specific cases find that optimal combination of two policy instruments...

Agri-environmental programs are part of the green box of the GATT Uruguay Round and are supposed to "have no, or at most minimal trade distorting effects or effects on production." In addition, "the amount of payment shall be limited to the extra costs or loss of income involved in complying...
