This empirical study investigates the effects of different agri-environmental schemes on individual producer behaviour. We consider the effects on production intensity, performance and structure for a sample of UK cereal farms for the period 2000 to 2009 and use the policy examples of the...

Copulas have become an important analytic tool for characterizing multivariate distributions and dependence. One is often interested in simulating data from copula estimates. The process can be analytically and computationally complex and usually involves steps that are unique to a given...

Suppression of employment records in the US County Business Patterns (CBP) data sets constrains the detail of new methods and recent advances in the analysis of the geographic distribution of firms and employment. Data sets created by imputation procedures can be purchased, but cost often puts...

In this study, we empirically examine the effectiveness of regulatory actions on wastewater treatment plants in Illinois with careful attention to endogeneity issues that might have caused biased estimates in previous studies. We show that Pooled OLS and Fixed Effect models, which are the...

This study investigates the rationality of monthly revisions in annual forecasts of supply, demand and price for U.S. corn, cotton, soybeans, and wheat, published in the World Agricultural Supply and Demand Estimates over 1985/86-2010/11. The findings indicate that USDA's forecast revisions are...

In this paper, we contribute to the existing literature of global yield gap analysis by using geo-spatial dataset on crop yields, agro-climatic factors and selected socio-economic variables. In line with the literature, we link yield gaps to technical efficiencies. By treating each grid-cell as...

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...
