An optimization model is used to evaluate the economics of various components of a large agribusiness. The benefits of using interger programming are contrasted to traditional linear programming analysis in conjunction with outside-the-model budgeting analysis.

This paper examines the role that climate change might be playing in the declining returns to agricultural research. For this purpose, we estimate a cross-section time-series model of agricultural total factor productivity for the U.S. states over the period 1970–1999, with the inclusion of...

This paper examines the effect that climate has on Avian Influenza outbreak probability. The statistical analysis shows across a broad region the probability of an outbreak declines by 0.22% when the temperature rises 1 Celsius degree and increases by 0.34% when precipitation increases by...

Mathematical programming formulations can yield faulty answers. Models can be unbounded, infeasible, or optimal with unrealistic answers. This article presents techniques for theory-based discovery of the cause of faulty models. The approaches are demonstrated in the context of linear...

Systematic approaches to validation of linear programming models are discussed for prescriptive and predictive applications to economic problems. Specific references are made to a general linear programming formulation, however, the approaches are applicable to mathematical programming...

Use of generalized stochastic dominance (GSD) requires one to place lower and upper bounds on the risk aversion coefficient. This study showed that breakeven risk aversion coefficients found assuming the exponential utility function delineate the places where GSD preferences switch between...

Multivariate probit analysis of BMP adoption, based on Louisiana sugarcane producer data, indicates that education and cost-sharing programs are effective means of increasing adoption rates. Results also indicate that contemporaneous correlation exists within and between management measures,...

This paper develops an option value model to examine the extent to which output price uncertainty creates incentives to adopt two interrelated components of site-specific technologies sequentially. It analyzes how the impact of uncertainty on the sequential adoption decision differs across...

A model of a (convex) technology of representative and non-representative firms in a heterogeneous sector is presented in non-parametric and parametric versions. The heterogeneity is specified with error terms. The models including a non-parametric distribution of the errors can be estimated...
