Macroeconomists acknowledge the contribution of human capital to economic growth, but their empirical studies define human capital solely in terms of schooling. In this paper, we extend production function models of economic growth to account for two additional variables that microeconomists...

This paper develops a unified model of growth, population, and technological progress that is consistent with long-term historical evidence. The economy endogenously evolves through three phases. In the Malthusian regime, population growth is positively related to the level of income per capita....

This paper examines a novel mechanism linking fertility and growth. Household fertility is determined by relative wages of women and men. Increasing women's wages reduces fertility by raising the cost of children relatively more than household income. Lower fertility raises the level of capital...

Economists use micro-based and macro-based approaches to assess the effects of health on economic growth. The micro-based approach tends to find smaller effects than the macro-based approach, thus presenting a micro-macro puzzle regarding the economic return on health. We reconcile these two...

The "Easterlin paradox" suggests that there is no link between a society's economic development and its average level of happiness. We re-assess this paradox analyzing multiple rich datasets spanning many decades. Using recent data on a broader array of countries, we establish a clear positive...

Increases in the proportion of the working age population can yield a "demographic dividend" that enhances the rate of economic growth. We estimate the parameters of an economic growth model with a cross section of countries over the period 1960 to 1980 and investigate whether the inclusion of...

We test the view the large differences in income levels we see across the world are due to differences in underlying characteristics, i.e. fundamental forces, against the alternative that there are poverty traps. Taking geographical variables as fundamental characteristics, we find that we can...

Technological diffusion implies a form of 'conditional convergence' as lagging countries catch up with technological leaders. We find strong evidence of technological diffusion but not full convergence; differences in total factor productivity (TFP) persist even in the long run due to differences...

For decades, economists and social thinkers have debated the influence of population change on economic growth. Three alternative positions define this debate: that population growth restricts, promotes, or is independent of economic growth. Proponents of each explanation can find evidence to...

This paper develops the theoretical foundations and the testable implications of the various mechanisms that have been proposed as possible triggers for the demographic transition. Moreover, it examines the empirical validity of each of the theories and their significance for the understanding...
