Since World War II, mortality has declined in the developing world. This paper examines the effects of this mortality decline on demographic and economic growth by a family-optimization model, in which fertility is endogenous and wealth yields utility through its status. The decline in mortality...

R&D-based growth theory suggests that a larger population size raises either the long-run rate of economic growth (strong scale effect) or the level of per capita income (weak scale effect), with far-reaching policy implications. However, for modern times there is little empirical support for...

The paper develops a model with non-exponential population growth, nonrenewable natural resources, and endogenous knowledge creation to analyse substitution between primary inputs and an essential use of resources in the innovation sectors, which is generally considered as most unfavourable for...

The paper develops an integrated baseline model to assess the trade-offs be- tween the natural environment and economic growth. Consumption growth is considered under welfare and sustainability aspects. The framework features capital accumulation and the sectoral structure of the economy as key...

Seit dem Zusammenbruch der DDR hat sich die Bevölkerungszahl in den ostdeutschen Flächenländern um 2,1 Millionen Personen vermindert; dies sind 13,7 Prozent der ursprünglichen Einwohnerzahl. Ausschlaggebend dafür waren nicht nur hohe Nettoabwanderungen insbesondere bei jüngeren...

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...

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...

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...

Slower growth of the labour force and an increase in old-age dependency will reduce the growth of aggregate output and output per capita in many developed countries. However, a major question is whether there is any systematic link between demographics and the productivity of those who will...
