Computable General Equilibrium (CGE) models are increasingly used for global trade policy analyses. This thesis addresses three issues that have arisen in this context. The first is the question of model validation: Do these models capture the kind of behavior actually observed in markets? The...

This paper incorporates commodity stockholding into a short run, stochastic global general equilibrium model. A mix of econometric and calibration techniques are used to reconcile model outcomes with historical stockholding and price behavior. The resulting framework is useful for analyzing...

Computable General Equilibrium (CGE) models are commonly used for global agricultural market analysis. However, concerns are sometimes raised about the quality of their output since key parameters may not be econometrically estimated and little emphasis is generally given to model assessment....

Resumen: este estudio busca contribuir a la evaluación del impacto económico que una mayor liberalización comercial en el Hemisferio Occidental, puede tener sobre los países miembros de la Comunidad Andina. Los escenarios de liberalización comercial más significativos se identifican y...

In this study we evaluate the effect of annual productivity growth in agriculture over the 1991-2001 period on poverty in eleven developing countries. We compare this with the optimal pattern of productivity growth of comparable cost with the sole goal of maximizing poverty reduction. This...

Trade policy reform prospects have generated debate about the impacts on poverty. Some critics assert that price changes induced by trade reform are minimal and may not be distinguishable from price fluctuations induced by other shocks to the global economy. This paper addresses this issue by...

This paper presents a validation experiment of a global CGE trade model widely used for analysis of trade liberalization. We focus on the ability of the model to reproduce price volatility in wheat markets. The literature on model validation is reviewed with an eye towards designing an...
