Climate volatility affects agricultural variability, and extreme climate outcomes have the potential to detrimentally affect food supply and prices in a given country. International trade has the potential to reduce the impacts of climate-induced food production variability, although it may...

Agriculture’s reliance on irrigation and concerns over water scarcity raise the question of how global food output and trade could be affected if the issue of water shortfall needs to be resolved on the back of agriculture. To understand changes in food production and international...

This paper outlines a conceptual framework for dealing with non-efficiency objectives in the pricing of publicly controlled natural resources. A general equilibrium model is developed and issues of model specification and solution are discussed. Finally, a numerical example serves to illustrate...

Mitigating the potential impacts of climate change is one of the leading environmental policy concerns of the 21st Century. However, there continues to be heated debate about the nature, content and, most importantly, about the impact of the policy actions needed to limit greenhouse gas...

Given the likely absence of a “top-down” global agreement after the 2012 expiry of the Kyoto Protocol, many countries (or groups of countries) may only be prepared to introduce a price on GHG emissions if they can maintain the competitiveness of their domestic sectors and prevent leakage...

Climate volatility will increase in the future, with agricultural productivity expected to become increasingly volatile as well. For Tanzania, where food production and prices are sensitive to the climate, rising climate volatility can have severe implications for poverty. We develop and use an...

Several studies in the recent past have offered a contrasting and wide range of perspectives on economic and environmental implications of biofuels. In this study we develop a comprehensive and consistent framework for analyzing the global economic interactions and the direct and indirect...
