This paper presents a general-equilibrium model of endogenous skilled-biased technological change and matching unemployment in a disaggregated economy. We simultaneously endogenise both the direction and pace of technological change as well as the unemployment rates. We show that an increase in...

Die Ergebnisse der kürzlich veröffentlichten PISA-Studie (OECD 2001) über den Bildungsstand der jüngeren Generation haben nicht nur zu einem Nachdenken über die Ursachen der für Deutschland sehr enttäuschenden Ergebnisse geführt, sondern auch die Diskussion über die Bedeutung von...

Traditional game theory usually relies on commonly known decision rationality meaning that choices are made in view of their consequences (the shadow of the future). Evolutionary game theory, however, denies any cognitive deliberation by assuming that choice behavior evolves due to its past...

We develop a dynamic general equilibrium model of education, quality and variety innovation, and scale-invariant growth. The early endogenous innovation-based growth models incorporate a scale e?ect predicting that larger economies are characterized by higher per capita growth rates. Recent...

In case of multiple creditors a coordination problem can arise when the borrowingfirm runs into financial distress. Even if the project's value at maturity is enoughto pay all creditors in full, some creditors may be tempted to foreclose on theirloans. We develop a model of creditor coordination...

In this paper, we analyze how to utilize discount rates in intergenerational projects. Firstly, neoclassical decision-making is depicted in Ramsey and overlapping-generations models (OLG-models). Afterwards we investigate the utilization of time preference rates and opportunity cost rates in an...

This paper analyses the choice of an inter-generational discount rate as well as a method for inter-generational discounting. It is shown that the pure time preference rate is irrelevant for inter-generational comparisons. However, the application of the growth time preference rate - with...

Die präsentierte Studie untersuchte Bestimmungsgründe der F&E-Tätigkeit von deutschen Industrieunternehmen im Zeitraum von 1992 bis 2000. Die modelltheoretischen Analysen dienten dazu, testbare Hypothesen über wesentliche Einflussfaktoren und deren Wirkungsrichtungen auf die F&E-Aktivitäten...
