We show with the aid of pooled OLS estimations that investments in improved road infrastructure have the potential to signficantly reduce transport costs. However, this result can only be clearly con rmed for industrial countries and is of primary importance for production and transportation of...

The author shows with pooled OLS estimations based on transport margins from international social accounting data that investments in improved road infra¬structure have the potential to significantly reduce transport costs. However, this result can only be clearly confirmed for industrial...

This paper investigates the robustness of CGE models with respect to the elasticities of substitution in demand between domestically produced goods and foreign goods – the so-called Armington elasticities. The Armington-type modeling of trade is still one of the most extensively used...

CGE models are widely used for policy evaluation and impact analysis especially with respect to trade reforms, tax reforms, energy sector reform and development policy analysis. However, the results of such models are often argued to be sensitive to the choice of exogenous parameters such as...
