We analyze the impact of obsolescence of economic inventions by incorporating maintenance costsin the endogenous growth model of expanding product varieties. This contrasts with the existingliterature, which ignores maintenance costs and uses the model of quality improvements todescribe...

We show that the two-sector version of the AK model proposed by Rebelo (1991) can be read as an endogenous growth extension of Greenwood, Hercowitz and Krusell (1997). By confining constant returns to capital to the investment goods sector, the model generates endogenously the secular downward...

This paper addresses the question of sectoral specialisation mechanisms and effects on growth rate differences providing an alternative approach to endogenous growth processes. The framework we choose draws on the Kaldorian cumulative causation approach to growth and the evolutionary modelling...

This paper studies an agent-based model that bridges Keynesian theories of demandgeneration and Schumpeterian theories of technology-fueled economic growth. We employ the model to investigate the properties of macroeconomic dynamics and the impact of public polices on supply, demand and the...

In der vorliegenden Arbeit wird ein Modell beschrieben, mit dem Ungleichverteilungen von VC untersucht werden. Im Zentrum stehen zwei Hypothesen: Die Spezialisierungshypothese, nach deren Aussage kein stattlicher Eingriff erforderlich ist, und die Hypothese der ineffizienten...

During the last years the relationship between financial development and economic growth has received widespread attention in the literature on growth and development. This paper summarises in its first part the results of this research, stressing the growth-enhancing effects of an increased...

We study structural change in a simple, two-sector endogenous growth model and show that the presence of commodity-specific consumption externalities can be a source of structural change. When the degrees of consumption externalities are different between different goods, the two sectors grow at...

When a continuum of technologies is introduced to the model of Grossman and Helpman (1991), both continuous and discrete technological progress may occur as a result of technology choices by private firms. A good is created through R&D based on one of a continuum of technologies that differ in...

The apparently unrelenting growth in the GDP-share of health spending (SHS) has been a perennial issue of policy concern. Does an equilibrium limit exist? The issue has been left open in recent dynamic models which take income growth and population aging as given. We view these variables as...
