The purpose of this article is to identify the role of population size, population growth and population ageing in models of endogenous economic growth. While in exogenous growth models demographic variables are linked to economic prosperity mainly via the population size, the structure of the...

This article introduces a social planner version of a model central to the New Economic Geography for explicitly answering whether the symmetric equilibrium outcome of the decentralized market economy is socially desirable. We find that savings incentives are too weak, resulting in an...

In summer 2007, the US subprime crisis emerged and economic growth in industrialised countries started to slow down. The situation deteriorated after the default of Lehman Brothers in September 2008 and despite massive government interventions, the United States and most European countries slid...

This article investigates the effects of introducing demography into the New Economic Geography. We generalize the constructed capital approach, which relies on infinite individual planning horizons, by introducing mortality. The resulting overlapping generation framework with heterogeneous...

Persistent low fertility rates lead to lower population growth rates and eventually also to decreasing population sizes in most industrialized countries. There are fears that this demographic development is associated with declines in per capita GDP and possibly also increasing inequality of the...

This article investigates agglomeration processes in ageing societies by introducing an overlapping generation structure into a New Economic Geography model. Whether higher economic integration leads to spatial concentration of economic activity crucially hinges on the economies' demographic...

This article investigates the consequences of population ageing for long-run economic growth perspectives. We introduce population ageing into a generalized model of endogenous technological change incorporating the model of Romer (1990) and Jones (1995) as special cases. We find that increases...

Conventional R&D-based growth theory suggests that productivity growth is positively correlated with population size or population growth, an implication which is hard to see in the data. Here we integrate micro-founded fertility and schooling into an otherwise standard R&D-based growth model....

We consider an endogenous growth model with Blanchard-Yaari-type overlapping generations that is built around four sectors: final and intermediate goods production, an R&D sector and a health care sector. Health care serves to lower mortality and morbidity, the latter being related to...

We assess Africa's prospects for enjoying a demographic dividend. While fertility rates and dependency ratios in Africa remain high, they have started to decline. According to United Nations projections, they will fall further in the coming decades such that by the mid-21st century the ratio of...
