We study the distribution of economic activity, as proxied by lights at night, across 250,000 grid cells of average area 560 square kilometers. We first document that nearly half of the variation can be explained by a parsimonious set of physical geography attributes. A full set of country...

Because of their more limited inequality and more comprehensive social welfare systems, many perceive average welfare to be higher in Scandinavian societies than in the United States. Why then does the United States not adopt Scandinavian-style institutions? More generally, in an interdependent...

What is the effect of increasing life expectancy on economic growth? To answer this question, we exploit the international epidemiological transition, the wave of international health innovations and improvements that began in the 1940s. We obtain estimates of mortality by disease before the...

We assess quantitatively the effect of exogenous reductions in fertility on output per capita. Our simulation model allows for effects that run through schooling, the size and age structure of the population, capital accumulation, parental time input into child-rearing, and crowding of fixed...

Following on Keynes's Economic Possibilities for Our Grandchildren, this paper develops conjectures about the world we will leave to our grandchildren. It starts by outlining the 10 most important trends that have defined our economic, social, and political lives over the last 100 years. It then...

Goldin and Katz's The Race between Education and Technology is a monumental achievement that supplies a unified framework for interpreting how the demand and supply of human capital have shaped the distribution of earnings in the U.S. labor market over the 20th century. This essay reviews the...

GDP growth is often measured poorly for countries and rarely measured at all for cities or subnational regions. We propose a readily available proxy: satellite data on lights at night. We develop a statistical framework that uses lights growth to augment existing income growth measures, under...

We study a dynamic general equilibrium model where innovation takes the form of the introduction new goods, whose production requires skilled workers. Innovation is followed by a costly process of standardization, whereby these new goods are adapted to be produced using unskilled labor. Our...

Despite the major advances in information technology that have shaped the recent wave of globalization, openness to trade is still a political choice, and trade policy can change with shifts in domestic political equilibria. This paper suggests that a particular threat and a limiting factor to...

We provide evidence that democracy has a significant and robust positive effect on GDP. Our empirical strategy relies on a dichotomous measure of democracy coded from several sources to reduce measurement error and controls for country fixed effects and the rich dynamics of GDP, which otherwise...
