A procedure is developed to examine the ex-post impacts of improved maize varieties on poverty in rural Ethiopia. Yield and cost effects of adoption are estimated econometrically under assumptions of both homogeneous and heterogeneous treatment effects. A backward derivation procedure is...

We empirically address the implications of biofuel policy regarding major grains, to the subsequent evolution of the markets for calories from the three major grains, maize, wheat and rice. The implied market variables, namely, market price, consumption, and stocks, using a structurally...

Major externality cases are random accidents which are not adequately addressed by the deterministic environmental policy literature -­‐ that of Pigouvian taxes, abatement subsidies and cap-­‐and-­‐trade. We consider a risk-­‐neutral industry where firms control the probability...

The objective of this research is to determine the contribution of recent agricultural policy reforms in the E.U. on the use of crop protection products. Specifically, we concentrate on the 1992 CAP reforms. Our theoretical model adopts the multi-output generalization of the...

This article argues that the existing maze of pesticide policies reflects the multidimensionality of side effects of pesticide use that cannot be addressed by uniform policies. Pesticide policies will improve as (a) economic literacy among natural scientists and policymakers increases; (b)...

Over the last 150 years, agriculture has been subject to several waves of innovation which have significantly altered its institutional structures, its products and the way it is practised. Mechanical, biological and chemical innovations have, in turn, reduced labour requirements, increased...

The study examines the least-cost option of conserving landraces in-situ by the development of market friction instruments. The empirical examination is comprised of two closely-related studies on eggplant production and consumption sectors of India. An examination of the cost and return...

In this paper, we analyze the relationships between the prices of biodiesel, ethanol and related fuels and agricultural commodities with a use of minimal spanning trees and hierarchical trees. To distinguish between short-term and medium-term effects, we construct these trees for different...
