This paper attempts to give a meaning to the empty concept of subsidiarity. It examines various kinds of government activity with respect to the optimal layer of government in Europe at which these activities should be performed. The paper criticizes Europe's industrial policies and its...

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...

The European Monetary Union will involve socialization of existing seigniorage wealth of national central banks. This socialization will create windfall gains for countries with relatively low monetary bases such as France and the United Kingdom and will be disadvantageous for countries like...

The paper argues that Lucas overestimates the Friedman-Bailey type of welfare cost of inflation and neglects other important welfare effects. With an alternative interpretation of the non-observability of low interest rates than the one Lucas gave and the introduction of taxes that reduce the...

It is argued that a PAYGO system may have useful allocative functions in that it serves as an insurance against not having children and as an enforcement device for 'rotten kids' who are unwilling to pay their parents a pension. It is true that the system has a moral hazard effect in terms of...

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...

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 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...
