One key focus of the on-going debate on the integration of international financial markets have been measures to lengthen the maturity of foreign debt. Short-term debt is typically considered to be volatile and thus a potential trigger of currency crises. In contrast to the vivid policy debate...

The paper examines empirically the proposition that aid to poor countries is detrimental for external competitiveness, giving rise to Dutch disease type effects. At the aggregate level, aid is found to have a positive effect on growth of labour productivity. A sectoral decomposition shows that...

The paper starts with a short survey on the main ideas of portfolio theory. Based on this, mean-variance efficient portfolios (stock as well as bond portfolios) for German investors of different degrees of risk aversion are constructed. It is shown that for them international diversification of...

This paper examines how trade liberalization affects the innovation incentives of firms, and what this implies for industry productivity and social welfare. For this purpose we develop a reciprocal dumping model of international trade with heterogeneous firms and endogenous R&D. We identify two...

Although it is well known that Markov process theory, frequently applied in the literature on income convergence, imposes some very restrictive assumptions upon the data generating process, these assumptions have generally been taken for granted so far. The present paper proposes, resp. recalls...

The paper analyses a partial equilibrium outsourcing model with Cournot competition in intermediate good production. Final production is located in western Europe, whereas the intermediate good can be manufactured by a western (outsourcing) or eastern European supplier (offshore outsourcing)....

In this paper we introduce and test the hypothesis that the relation between inflation and unemployment has been in many countries subject to a significant change in the early 1990's after the disinflation period. That period began between 1975 and 1980 after the first (or the second) oil price...

It is often proposed that capital income tax rates be harmonized. Otherwise, a “race to the bottom” will occur and lead to governments not being able to perform their usual tasks. However, the development of corporate income tax revenues in relation to GDP does not indicate that a race to...

The European emissions trading scheme (EU-ETS) for CO2 is the largest existing emissions trading scheme in the world. The main reason for the implementation of this scheme is to reach the European Kyoto targets at minimal cost and to establish a price for emissions. The right to emit CO2...
