We survey grain and soybean handlers and producers in the U.S. and EU to estimate costs of preserving the identities of GMO and non-GMO crops in marketing channels. We introduce our estimates into the IFPRI IMPACT model to simulate the effects of identity preservation on farm incomes and...

This paper presents a theoretical economic model assessing the effect of the level of mandatory genetically modified (GM) / non-GM coexistence regulations on market and welfare outcome. We assume vertical differentiation of GM and non-GM goods on the consumer side. Producers are heterogeneous in...

In this paper, we conduct an empirical investigation of potential adoption of herbicide-tolerant (HT) genetically modified (GM) rapeseed in France. Our aim is to study ex ante the potential impact of their adoption in France, in terms of adoption level, economic gains, and distribution of these...

We show that whether intensive or extensive farming is most beneficial to biodiversity depends on the equilibrium of agricultural markets. With higher production costs, extensive farming tends to be more beneficial to biodiversity than intensive farming, except when there is a very high degree...

The paper presents a theory of policy timing that relies on uncertainty and transaction costs to explain the optimal timing and length of policy reforms. Delaying reforms resolves some uncertainty by gaining valuable information and saves transaction costs. Implementing reforms without waiting...

A brief review of the history of agricultural policymaking in Europe and the U.S. reveals that major policy changes have often been brought about by major socio-political "shocks," such as the Great Depression and World War II. Such shocks also lead to the creation of institutions that tend to...

Wallace's (1962) pioneering study brought to agricultural economics a focus on the role of supply and demand elasticity's in determining the efficiency with which agricultural policy transfers income among interest groups. His discussion provides key insights into what I call the "consequences...
