By contrasting endogenous growth models with facts, one is frequently confronted with the prediction that levels of economic variables, such as R&D expenditures, imply lasting effects on the growth rate of an economy. As stylized facts show, the research intensity in most advanced countries has...

We estimate a dynamic intertemporal model with non-clearing markets that mimics features of European labour markets, such as sticky nominal wages and sluggish adjustment of employment to shocks for 15 OECD countries. The estimates include a measure for the degree of labour market sluggishness...

We estimate a dynamic, intertemporal optimisation model that mimics features of European labour markets, such as sticky nominal wages and sluggish adjustment of employment to shocks for 15 OECD countries. The estimates include a measure for the degree of labour market sluggishness that compares...

Germany will be one of the core countries in the European Monetary Union (EMU). Currently there is therefore a great interest in issues of labor market and monetary policy in Germany. On the basis of a macroeconometric model we study the interaction of labor market and alternative monetary...

We estimate a dynamic, intertemporal optimisation model that mimics features of European labour markets, such as sticky nominal wages and sluggish adjustment of employment to shocks for 15 OECD countries. The estimates include a measure for the degree of labour market sluggishness that compares...

In the framework of a Keynesian based monetary macromodel we study the implications of alternative monetary policy rules. Our monetary macromodel exhibits the following features: asset market clearing, disequilibrium in the product and labor markets, sluggish price and quantity adjustments, two...

In this paper we test whether German public debt has been sustainable by resorting to a test proposed by Bohn (1998). We apply non-parametric and semi-parametric regressions with time depending coefficients. This test shows that the mean of the coefficient relevant for sustainability has been...

The paper considers the transition of an economy from non-renewable to renewable energy. The Hotelling theorem suggests to extract a non-renewable resource in an optimal way such that the resource tends to be depleted when optimally extracted. Yet,it might not be reasonable to deplete...
