This paper explores the potential production and land use effects of making subsidy payments subject to crop diversification. We first derive a theoretical model for a rational farmer who receives subsidies contingent on the degree of crop diversification. A state-contingent framework is used to show that crop diversification decisions are independent of risk preferences if farmers have access to off-farm opportunities, such as financial markets. Pricing equations for land allocation and output decisions are derived from the theoretical model and used in a Generalized Method of Moments framework to estimate parameters of interest. We use a panel of crop farms from France, Germany, Poland, and the UK obtained from the EU Farm Accounting Data Network (FADN).
