This study extends dynamic models of renewable terrestial resources to evaluate the optimal long-run management strategy for African Elephants. Changes in many model parameters have ambiguous effects on elephant stocks and point to a need for empirical research to provide parameterizations for a...

This paper describes the first use of a methodology based on a utility-theoretic behavioral model to simultaneously estimate a household's WTP for a non-market good in both money and a non-monetary numeraire good. WTP by subsistence farmers in Namibia for deterrents to wildlife attacks on crops...

Traditionally, the analysis of labor market adjustment refers to the interaction between the demand and the supply for labor, e.g., between employers and job seekers. The labor market is said to 'clear' when the wage and labor force participation adjust so that supply and demand are equal....

The paper develops and uses a two step quantitative model to analyze the effect of Foot and Mouth Disease (FMD) on international beef markets over time. Using monthly data from 1990-2002 for 7 major beef exporters and for 22 major beef importers, we use a probit equation to estimate the...

A stochastic dynamic programming model for extensive livestock systems is developed. The model optimizes sales/retention decisions when future forage production, which affects animal performance and hence profitability, is uncertain. The model is applied to sheep production in Kazakhstan to...
