Germany has had an extremely low growth performance since 1995. The paper looks at the long-run reasons for this loss of economic dynamics besides German unification: These include leaving labor idle, a declining share of investment in GDP, a weaker innovative activity, an ineffective system for...

Phenomena such as the Great Moderation have increased the attention of macro-economists towards models where shock processes are not (log-) normal. This paper studies a class of discrete-time rational expectations models where the variance of exogenous innovations is subject to stochastic regime...

We explore the increasing divergence between economic growth and energy consumption through energy-saving technical progress. Proposing a new measure of energy-saving technology, we study the underlying drivers in a semi-structural model of the U.S. economy. Our analysis shows that energy price...

Trade and industrial policies, while primarily intended to support domestic industries, may unintentionally stimulate technological progress abroad. We document this mechanism in the case of rare earth elements (REEs) - critical inputs for manufacturing at the knowledge frontier, with low...

To facilitate the transformation of the German economy from the traditional manufacturing industries towards emerging new technologies, a new segment of the Frankfurt exchange was introduced in 1997 - Der Neue Markt. This study provides evidence that not only did many new firms obtain funding...

This paper studies how the assignment of patents as collateral determines the savings of firms and magnifies the effect of innovative rents on investment in research and development (R&D). We analyse the behaviour of innovative firms that face random and lumpy investment opportunities in R&D....

In dieser Arbeit wird ein Überblick über einige Kernaussagen der ''Neuen Wachstumstheorie'' über den Zusammenhang von Wissen und wirtschaftlicher Entwicklung gegeben. Ausgehend von der ''neoklassischen'' Wachstumstheorie wird die Bedeutung von Wissen in Prototypen endogenen Wachstums der...

Productivity dispersion across firms is large and persistent, and worker reallocation among firms is an important source of productivity growth. The purpose of the paper is to estimate the structure of an equilibrium model of growth through innovation that explains these facts. The model is a...
