We describe four recently developed panel data estimators for unbalanced and nested data, a common problem for economic and experimental data. We estimate a western corn rootworm damage function with each estimator, including separate parameters for random effects from year, location, and...

In this paper we examine price transmission for major agriculture (food) and energy products in China for the years 2004 to 2010. The Error correction model (ECM) and the directed acyclic graphs (DAG) are applied to identify price dynamics among these six variables: rice, wheat, corn, coal,...

The bank lending channel states that changes in monetary policy cause changes in bank loans thus causing changes in real income. This implies the Federal Reserve can influence real income by controlling the level of intermediated loans. We apply a new method to test for an operative bank lending...

We analyze the effects of crop insurance and the Marketing Loan Program on optimal nitrogen use and acreage allocation for a case cotton-sorghum farm in Texas. A mathematical programming model is used to simulate the optimal nitrogen fertilizer rate, crop acreage allocation, coverage level, and...

Water scarcity has been a significant issue for several decades in the Texas High Plains, with agriculture identified as the main activity contributing to this scarcity. To address this issue, much effort has been devoted to developing and encouraging adoption of sophisticated irrigation systems...

Using a principal-agent model, we find the optimal subsidy contract that induces grower compliance with Bt corn refuge requirements for managing insect resistance when asymmetric information exists concerning grower behavior. The optimal contract balances the cost of monitoring and the benefit...

Economic analyses of pests typically assume damage is either additively separable from pest free yield or proportional to it. This paper describes the ecological assumptions required for additive and proportional damage functions to demonstrate that both specifications are reasonable. Ecological...

This paper describes a composed error model for estimating the conditional distribution of yield loss to serve as an insect damage function. The two-part error separates yield variability due to pest damage from other non-pest factors such as soil heterogeneity, non-uniform application of...

Given the importance of adopting weed resistance management BMPs, it is important to develop methods to compare BMP adoption among farms and to identify factors that affect BMP adoption. Because of the relatively large number of BMPs and interactions among them, a composite index that integrates...
