The main objective of this paper is to test the hypothesis that consumer preferences for beef in the United States have been affected by structural change, which reduces to testing for parameter stability in estimated demand equations. To this end, alternative specifications of the demand...

In this article, the author reviews intellectual property rights (IPRs), with some emphasis on the protection of agricultural and life sciences innovations. The main institutional features of IPRs are first discussed, along with a brief historical background and an articulation of the main...

When lump-sum taxation is not feasible, decoupled transfers to farmers (which require raising government revenue) will entail welfare loss somewhere in the economy. Assuming the government's objective is to assure a given welfare level for farmers, we show that when decoupling is possible, free...

We derive a general elasticity representation of the necessary and sufficient conditions for direct weak separability of the utility function. Parametric restrictions required to implement the separability conditions are presented for three common demand systems: the Almost Ideal, Translog, and...

This paper develops a separable functional form in which all the relevant aggregator functions are modeled to the desired degree of approximation. This leads to separable structures that are more flexible than those implied by parametric restrictions of flexible functional forms. Tests of...

This paper analyzes the optimal production and hedging decisions for firms facing futures price, basis and production risk, assuming futures and options can be used. Using CARA (constant absolute risk aversion) utility and normal distributions, we derive an exact solution and show that joint...
