Census data from international sources covering 77% of the world's migrant population indicate that the skill composition of migrants in major destination countries, including the US, has been rising over the last four decades. Moreover, the population share of skilled migrants has been...

The worldwide problem with pay-as-you-go, defined-benefits social security systems isn't just financial. Through a dynamic, overlapping-generations model where forming a family and bearing and educating children are choice variables, we show that social security taxes and benefits generate...

There is growing concern about a decline in the total fertility rate worldwide, but nowhere is the concern greater than in OECD countries, some of which already face the prospect of population decline as well. While the trend is largely the result of structural economic and social changes, our...

Using an endogenous-growth, overlapping-generations framework where human capital is the engine of growth, we trace the dynamic evolution of income and fertility distributions and their interdependencies over three endogenous phases of economic development. In our model, heterogeneous families...

Using an endogenous-growth, overlapping-generations framework where human capital is the engine of growth, we derive propositions concerning the evolution of income and fertility distributions and their interdependencies over three phases of economic development. In our model, heterogeneous...

The 19th century economist, Thomas Robert Malthus, hypothesized that the long-run supply of labor is completely elastic at a fixed wage-income level because population growth tends to outstrip real output growth. Dynamic equilibrium with constant income and population is achieved through...

Using an endogenous‐growth, overlapping‐generations framework in which human capital is the engine of growth, we trace the dynamic evolution of income and fertility distributions and their interdependencies over three endogenous phases of economic development. In our model, heterogeneous...

The worldwide problem with pay-as-you-go (PAYG) social security systems isn't just financial. This study indicates that these systems may have exerted adverse effects on key demographic factors, private savings, and long-term growth rates. Through a comprehensive endogenous-growth model where...
