The Multi-purpose Tree (MPT) species have the ability to fit into the farming systems of the East African region where low agricultural productivity, widespread land degradation and hence a diminishing capacity to support the growing human and livestock population are major problems. GIS has...

Development is a human problem and is aimed at changing man and his economic, social, ecological environment. Throughout history, man has acquired new knowledge to shape his future. As human needs multiplied and became more complex, science and technology – processes of systematic inquiry for...

The paper investigates price dynamics under market liberalization, with a focus on the effects of lowering price floors. We analyze price dynamics by specifying and estimating a dynamic Tobit model under time-varying volatility, where the market price is censored by a government-set support...

This paper presents an econometric analysis of the effects of price support program and stocks on price dynamics and price volatility. Considering a price support program as a censoring scheme, market prices are specified as a dynamic Tobit model under time varying volatility. The model is...

The paper investigates the implications of hedonic pricing of components, with an application to the dynamics of dairy product prices. A conceptual model of hedonic pricing is developed under a Leontief technology, showing how commodity prices reflect the underlying value of their components....

A central result in the theoretical literature on strategic trade is the ërent-shifting hypothesisí, the idea that governmentís can employ trade policy as a precommitment device to transfer profit from foreign to domestic firms. To our knowledge, however, the rent-shifting hypothesis remains...

In this paper, we modeled the economic linkages between a commodity (wheat gluten) and a commodity characteristic (wheat protein). The purpose of this research was to address several issues in the wheat protein complex including the impact of the U.S. gluten import quota on producer protein...

The paper bases itself on recent theoretical writings in growth economics that emphasize the effects of both own R&D efforts and of interregional technology spillovers on regions´ productivity. We propose robust estimation techniques to evaluate the R&D spillovers across West German functional...

Commodity levies are used increasingly to fund producer collective goods such as research and promotion. In the present paper we examine theoretical relationships between producer and national benefits from levy‐funded research, and consider the implications for the appropriate rates of...
