Agriculture is in the business of using ecosystem services to produce food. Examining how agro-ecosystems function provides useful insights into the economics of agriculture. Of special interest are the presence and nature of scale effects, complementarity effects and convexity effects in...

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...

U S grain prices affect one another This study uses Haugh-Pierce chi-square tests, bivariate autoregressive models, and dynamic multipliers to measure the extent of these effects Rice prices exhibit very little reaction to changes in other grain prices However, other grain prices relate closely...

The paper considers an industry transforming primary commodities (farm products) into processed commodities (food products). It focuses on the allocation of embedded characteristics (carbohydrate, protein, etc.) both across space and among commodities. The approach generates a spatial...

This paper develops an economic and econometric analysis of demand dynamics, with an application to US aggregate data over the period 1948-2010. The model builds on duality and the benefit function, which provide strong linkages with the theory. The research involves the specification and...

This paper presents a general equilibrium analysis of economic efficiency under externalities, transaction costs and non-convexity. It applies to market exchange as well as contractual arrangements. We show that the Coase theorem continues to hold under general conditions: the efficient...

This article analyzes the dynamic relationships among weekly prices of price byproducts, long gram rice, and corn, using causality tests and dynamic multipliers The authors use forecasts to evaluate the time series model rice byproducts prices may be influenced more by shifts 10 demand than 10...
