Topic Relevance Foliar diseases often reduce grain yields of winter wheat in the southern Great Plains, with some individual year yield losses in excess of 10%. At current prices, the gross value of these losses for the region could exceed a quarter of a billion dollars annually. Historically,...

This paper investigates the nonparametric analysis of technology under non-convexity. The analysis extends two approaches now commonly used in efficiency and productivity analysis: Data Envelopment Analysis (DEA) where convexity is imposed; and Free Disposal Hull (FDH) models. We argue that, while...

The National Policy Statement on Freshwater Management now requires that water quality objectives and limits be set for all water bodies in New Zealand. Where objectives result in the development of nitrate limits for waterways and development pressure is likely to make these limits difficult to...

Perennial crop production is inherently dynamic due to several salient physical characteristics including an establishment period of several years with low or no yields, long lives in commercial production (40 years or more), and path-dependence of yields on input use and other exogenous...

This study investigates the impact of risk preferences on economic efficiency scores. Risk averse individuals may be less likely to adopt new technologies and have lower production levels than individuals with other risk preferences. Nonparametric techniques are used to estimate cost and revenue...

A method for taking uncertainty into account when formulating aggregate agricultural policies is applied to the feed grain program. The impact of alternative feed grain programs on net farm income, Government payments, and feed grain production in the Southeastern Coastal Plains is shown. A...
