We develop a dynamic stochastic general-equilibrium model of science, education and innovation to explain the simultaneous emergence of innovation clusters and stochastic growth cycles. Firms devote human-capital resources to research activities in order to invent higher quality products. The...

This paper examines optimal two-period financial contracts between firms in a product market on the one side and banks as creditors on the other side. Similar to the Bolton-Scharfstein contracts, banks can mitigate the moral hazard problem of truthfully revealing the ex ante unknown profits of...

This paper presents a general-equilibrium model of Innovation, endogenous growth, and unemployment in a disaggregated economy. Unemployment is analyzed w ithin a dual labor market setting, where the labor market is consisting of a primary high-wage and a secondary low-wage sector. The...

This paper analyzes the influence of Information structure on the process of knowledge accumulation in a differential game of duopolistic R&D competition. By comparing open-loop and feedback Nash equilibria, representing imperfect and perfect information structures, we show that in the feedback...

Aufgabe des vorliegenden Beitrages ist es, die wesentlichen Elemente und die Funktionsweise des strukturalistischen Ansatzes darzustellen und ihn auf seine Erklärungskraft bzgl. der empirisch festzustellenden andauernden Arbeitslosigkeit in den westlichen Industrieländern zu überprüfen. Eine...

The paper presents a dynamic general-equilibrium model of education, quality and variety innovation, and scale-invariant growth. We consider endogenous humancapital accumulation in an educational sector and quality and variety innovation in two separate R&D sectors. In the balanced growth...
