The study measures farm credit risk by using farm records collected by Farm Business Farm Management (FBFM) during the period 1995-2004. The study addresses the following questions: 1) whether farm’s financial position is fully described by the structure model, 2) what are the determinants of...

Shadow prices indicate implicit values of limited resources at the margin and provide important information in decision making for resource management. In continuous economic models, shadow prices associated with demand-supply balance constraints represent consumers' willingness to pay and...

Biofuel production is being promoted through various policies such as mandates and tax credits. This paper uses a dynamic, spatial, multi-market equilibrium model, Biofuel and Environmental Policy Analysis Model (BEPAM), to estimate the effects of these policies on cropland allocation, food and...

This paper introduces a computationally convenient measure of structural diversity based on absolute deviations between relative shares of individual groups forming a community. A conceptual framework is developed, some theoretical properties of the measure are derived, and its close relation to...

While there is no dearth of regression analyses or linear programming models reviewing the agricultural performance of Pakistan, hardly any study has used a price endogenous mathematical programming model to simulate the ex ante effects of new policies on consumers and producers simultaneously....

We develop an aerodynamic loading assignment model for intermodal freight trains based on an integer-programming framework to help terminal managers make up more fuel-efficient trains. This is the first use of optimization modeling to address the aerodynamics and energy efficiency of railroad...
