Using a large cross-country income distribution dataset spanning close to 800 country-year observations from industrial and developing countries, the authors show that the size distribution of per capita income is well approximated empirically by a lognormal density.

This paper provides an empirical evaluation of the impact of infrastructure development on economic growth and income distribution using a large panel data set encompassing over 100 countries and spanning the years 1960-2000. The empirical strategy involves the estimation of simple equations for...

We show how to relate the welfare of a country's infinitely-lived representative consumer to observable aggregate data. To a first order, welfare is summarized by total factor productivity and by the capital stock per capita. These variables suffice to calculate welfare changes within a country,...

This paper offers an empirical evaluation of the output contribution of infrastructure. Drawing from a large data set on infrastructure stocks covering 88 countries and spanning the years 1960-2000, and using a panel time-series approach, the paper estimates a long-run aggregate production...
