Lobbying activities bias the political decision-making process. There tend to be deviations from the socially-optimal solutions. This paper shows that in an international context, this bias is not necessarily harmful in terms of economic welfare. It may correct externalities that occur in an...

Does international tax competition in the environmental field lead to undesirably low levels of environmental regulation and to unacceptable standards of environmental quality? The paper attempts to answer this question in a non-competitive partial-equilibrium framework. There is one firm that...

It has been argued in the literature that interjurisdictional competition forces the public sector to increase its efficiency and thus helps to tame Leviathan governments. The paper addresses this hypothesis by means of a simple tax-competition model with a Leviathan state. It is seen that the...

International trade and environmental regulation are interdependent. Central and East European Countries (CEECs) are now being integrated in international markets, and the question arises how environmental issues should be taken account of during this process and which institutional framework is...

We build a two-sector dynamic general equilibrium model with one-sided substitutability between fossil carbon and biocarbon. One shock only, the discovery of the technology to use fossil fuels, leads to a transition from an inital pre-industrial phase to three following phases: a pure fossil...

Open borders imply systems competition. This paper studies the implications of systems competition for the national competition rules. It is shown that an equilibrium where all countries retain their antitrust laws does not exist, since abolishing this law makes it possible for a single country...

The paper discusses the options for a reform of the German pension system using a model developed at CES for the German Council of economic advisors to the Federal Ministry of Economics and Research. It is argued that the German pay-as-you-go-system is efficient in a present value sense but will...

The paper studies the role of international implications after EU enlargement. Based on a formal model with migration costs for both capital and labor, it predicts a two-sided migration from the new to the old EU countries which is later reversed. As the migration pattern chosen by market forces...

Economic development in East Germany is not uniform. The building and construction industry is booming but manufacturing industry is stagnating. The paper argues that severe distortions in relative factor prices are the cause of the dichotomous development. These distortions result from...

It is shown that the net fiscal externality created by an additional member of a pay-as-you-go-pension system that is endowed with individual accounts equals the gross contributions of this member. In Germany, this equals about 175,000 Deutsche marks. The paper uses this information to design a...
