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...

This paper provides quasi-experimental estimates of the causal effect of long-term unemployment on wages. Using standard job search theory, the paper derives and tests conditions on reemployment wages under which Unemployment Insurance (UI) extensions can be used as instrumental variables (IV)...

The nature of the relationship between employers and employees has been changing over the last decades, with firms increasingly relying on contractors, temp agencies and franchises rather than hiring employees directly. We investigate the impact of this transformation on the wage structure by...

Squaring hourly demand and wind-solar production data for Germany and a number of neighbouring countries with the results of the EU's ESTORAGE project, this paper studies the limits of Germany's energy revolution in view of the volatility of wind and solar power. In addition to pumped storage,...

We use the expansion of the high-speed rail network in Germany as a natural experiment to examine the causal effect of reductions in commuting time between regions on the commuting decisions of workers and their choices regarding where to live and where to work. We exploit three key features in...

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 upcoming demographic crisis in Germany demands fundamental reforms of the pension system. In a democracy, reforms are, however, only feasible when they are supported by the majority of the electorate. To determine whether the majority is in favor of reforms of the pension system, we...

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...

Administrative datasets provide an excellent source for detailed analysis of establishment entries and exits on a fine and disaggregate level. However, administrative datasets are not without problems: restructuring and relabeling of firms is often poorly measured and can create large biases....

The job finding rate of Unemployment Insurance (UI) recipients declines in the initial months of unemployment and then exhibits a spike at the benefit exhaustion point. A range of theoretical explanations have been proposed, but those are hard to disentangle using data on job finding alone. To...
