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...

An important strand of research in macro-finance investigates which factors impede enterprise investment, and quantifies their aggregate cost. In this paper, we make two contributions to this literature. The first contribution is methodological: we introduce a novel framework to calibrate...

Why does inequality vary across societies? We advance the hypothesis that in a market economy, where earning differentials reflect variations in productive traits, a significant component of the differences in income inequality across societies can be attributed to variation in societal...
