The exclusivity conferred to inventors by intellectual property rights (IPRs) provide an ex ante incentive for innovation, but the resulting market power yields an ex post inefficiency (because it limits use of the innovation). Strong IPRs may also affect innovation by limiting access of...

I model a scoring situation that arises frequently during soccer matches. The Nash equilibrium solution is shown to be broadly consistent with the conventional wisdom of experts. Data on goals scored over an entire season in Italyï¾’s soccer league provide statistical support for a...

The necessary and sufficient conditions for direct weak separability are used to derive restrictions on the parameters of the Almost Ideal (AI) demand system, yielding a systematic way of restricting the parameter space that may be useful for estimating large demand systems. The proposed method...

This paper analyzes the impacts of policy reforms in the EU dairy sector. It is shown that the imple-mentation of GATT agreements leads to a 4% decrease in the milk price. Prices of SMP and WMP decrease more than butter and cheese prices. EU welfare increases marginally, but distributive effects...

We revisit the question of choosing partial equilibrium or general equilibrium modeling in applied policy analysis in the context of evaluating the effects of a complete phase-out of the Common Agricultural Policy (CAP) of the European Union. We compare the results of three models-two...

Food system regulators often decide whether to ban existing practices or approve new technologies without conclusive scientific evidence on possible damage and knowing that resolution is likely in the future. In a model with three decision points and stochastic resolution of uncertainty, we...

A partial equilibrium four-region world trade model for the soybean complex is developed in which Roundup Ready (RR) products are weakly inferior substitutes to conventional ones, RR seeds are priced at a premium, and costly segregation is necessary to separate conventional and biotech products....
