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...

This paper provides a critique of the ?unemployment invariance hypothesis,? according to which the behavior of the labor market ensures that the long-run unemployment rate is independent of the size of the capital stock, productivity, and the labor force. Using Solow growth and endogenous growth...

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...

In this note we compare the laissez-faire steady-state solution in the Howitt and Aghion (1998) model to the social optimum. The analysis offers several new insights in comparison to the welfare analysis in Aghion and Howitt (1992). We find various new distortions between private and optimal...

The paper provides an analysis of the recent immigration history of New Zealand and Australia. It starts with a description of the quantitative dimension of immigration: how many immigrants entered the two countries, and what was the contribution of external migration to population growth. Next,...

Two of the main forces driving European emigration in the late nineteenth century were real wage gaps between sending and receiving regions and demographic booms in the low-wage sending regions (directly augmenting the supply of potential movers as well as indirectly making already-measured...

Does a country?s level of unemployment have an impact on the long-run growth rate? Incorporating unemployment into a generalised augmented Solow-type growth model, yields some answers to this question. In particular, we show that the impact of unemployment on productivity growth heavily depends...
