This article deals with the specification of a locally flexible and theory-consistent system of mixed demand functions, a framework that allows for a rich set of possibilities about what is assumed as exogenous in a demand model. A coherent mixed demand system is derived by using the restricted...

This article employs a short-term specification of the symmetric generalised McFadden (SGM) cost function capable of accommodating quasi-fixed factors and variable returns. Temporary equilibrium and scale economies are investigated while maintaining the consistency of the estimated model with...

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...
