In this paper we investigate the potential production and implications of a global biofuels industry. We develop alternative approaches to consistently introduce land as an economic factor input and in physical terms into a computable general equilibrium framework. The approach allows us to...

A successful agreement on agriculture is essential for an overall agreement under the WTOÂ’s Doha trade negotiations. Reaching agreement has been difficult, and as of August 2007, much still remains to be done if a successful agreement is to be reached. We consider three of the most...

This paper provides estimates of the economic impact of initial adoption of genetically modified (GM) cotton and of its potential impacts beyond the few countries where it is currently common. Use is made of the latest version of the GTAP database and model. Our results suggest that by following...

Four West African nations have demanded the WTOÂ’s Doha Development Agenda include a Cotton Initiative that involves two issues: cutting cotton subsidies and tariffs, and assisting farm productivity growth in Africa. This paper provides estimates of the potential economic impacts of (a)...

Uncertainty about compliance costs causes otherwise equivalent price and quantity controls to behave differently. Price controls - in the form of taxes - fix the marginal cost of compliance and lead to uncertain levels of compliance. Meanwhile quantity controls - in the form of tradable permits...

The claim by global trade modelers that the potential contribution to global economic welfare of removing agricultural subsidies is less than one-tenth of that from removing agricultural tariffs puzzles many observers. To help explain that result, this paper first compares the OECD and...

In this paper the global agricultural land use model KLUM is coupled to an extended version of the computable general equilibrium model (CGE) GTAP in order to consistently assess the integrated impacts of climate change on global cropland allocation and its implication for economic development....
