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...

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...

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...

Investment in infrastructure is considered as a crucial prerequisite for economic development. Given the scarce resources for public investment in developing countries a detailed perspective on the effects of each form of infrastructure is needed. This paper focuses on transport infrastructure...

Numerous econometric studies fail to detect a signicant and robust relationship between international aid and economic growth in the recipient countries. Dutch Disease effects might be responsible for this result.This paper examines the relation between aid and its effectiveness in a...

Experience after the establishment of EMU shows that the behaviour of private consumers differs considerably among member countries and that average and marginal propensities to consume are fairly heterogeneous. In particular, there are clear differences between Germany and the rest of the euro...

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...
