Die Entwicklung der Bevölkerung geriet in Deutschland infolge der gegenwärtigen Finanzkrise der öffentlichen Haushalte und der Systeme sozialer Sicherung in den Focus des öffentlichen Interesses. Die in den meisten hochentwickelten Ländern sich abzeichnende Alterung und Schrumpfung der...

In this paper, a two-sector model of endogenous growth is extended to a multi-sector nonlinear dynamic input-output model. If the model is on its balanced growth path (where prices - but not quantities - are assumed constant over time), it can be shown that the linear dynamic Leontief model is a...

Most economic activity occurs in cities. This creates a tension between local increasing returns, implied by the existence of cities, and aggregate constant returns, implied by balanced growth. To address this tension, we develop a theory of economic growth in an urban environment. We show how...

This paper develops a monetary endogenous growth model where money is no longer superneutral. Economic growth is propelled by the accumulation of human capital and money enters into the optimization problem of the individual through a shopping-time techno

Die im Rahmen des vom Bundesministerium für Bildung und Forschung (BMBF) geförderten Projektes KompNet2011 - Erfolgsfaktoren regionaler Innovationsnetze - durchgeführte Befragung untersucht die Innovationskooperationen sowie Wissenstransferaktivitäten von schwerpunktmäßig kleinen und...

We conjecture that the mobility of academic scientists increases the propensity of such agents to engage in academic entrepreneurship. Our empirical analysis is based on a survey of researchers at the Max Planck Society in Germany. We find that mobile scientists are more likely to become nascent...
