This paper develops a model that integrates the climate and the global economy---an integrated assessment model---with which different policy scenarios can be analyzed and compared. The model is a dynamic stochastic general-equilibrium setup with a continuum of regions. Thus, it is a full...

We analyze a dynamic stochastic general-equilibrium (DSGE) model with an externality through climate change from using fossil energy. A central result of our paper is an analytical derivation of a simple formula for the marginal externality damage of emissions. This formula, which holds under...

We estimate an aggregate production function with constant elasticity of substitution between energy and a capital/labor composite using U.S. data. The implied measure of energy-saving technical change appears to respond strongly to the oil-price shocks in the 1970s and has a negative medium-run...

A political miracle occurred when Germany was reunited, and at first glance an economic miracle has followed. Real incomes in the east have now reached the western level, and investment per capita has been much higher than in the west. However, every third deutschmark spent in the east has been...

The European Monetary Union (EMU) will involve socialization of the existing seigniorage wealth of the national central banks, because the Euro will have to be bought by these banks in exchange for assets which have been accumulated in the historical process of money creation. This socialization...

This paper advances the hypothesis that the world debt crisis was mainly induced by the dramatic rise of US interest rates in the first half of the eighties. It sees this rise in interest rates primarily as a result of a tight US monetary policy and excessively large investment incentives...

This paper advances the hypothesis that the EUS crisis was caused by German unification. The unification has implied a massive resource demand which parallels the US resource demand following Reagan's tax reforms in the eighties. The resource demand revised the German interest rates relative to...

The paper comments on the economic effects of the German unification. Apart from discussing the unification in an international perspective, analyzing the distributional consequences, and pointing to structural adjustment problems, it emphasizes the distinction between the frequently cited money...

Based on explicit present value calculations, the paper criticizes the view that the PAYGO system wastes economic resources. In present value terms, there is nothing to be gained from a transition to funded system even though the latter offers a permanently higher rate of return. The sum of the...

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...
