This paper argues that increased factor mobility incurs the risk of dismantling the welfare state, even though this state may have useful allocative functions. It will be difficult to finance the welfare state with taxes on capital and it may be necessary to subsidize this factor in the sense...

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...

This paper advances the hypothesis that the EMS crisis was caused by German unification. Unification stimulated massive resource demand, which paralleled resource demand in the United States following Reagan’s tax reforms in the 1980s. The resource demand revised German interest rates relative...

This paper develops a model of a small open economy that produces an export good with domestic labour and imported energy and is stuck in an unemployment situation resulting from an excessive fixed net-of-tax wage rate. We study a revenue-neutral green tax reform that substitutes energy for wage...

The welfare state can be seen as an insurance device that makes lifetime careers safer, increases risk taking and suffers from moral hazard effects. Adopting this view, the paper studies the trade-off between average income and inequality, evaluating redistributive equilibria from an allocative...

This paper studies alternative methods of privatizing a formerly communist firm in the presence of imperfect risk markets. The methods include cash sales, a give-away scheme, and a participation contract where the government retains a sleeping fractional ownership in the firm. It is shown that...
