I use microeconomic estimates of the effect of health on individual outcomes to construct macroeconomic estimates of the proximate effect of health on GDP per capita. I employ avariety of methods to construct estimates of the return to health, which I combine with cross-country and historical...

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 construct a matrix showing the share of the year 2000 population in every country that is descended from people in different source countries in the year 1500. Using this matrix, we analyze how post-1500 migration has influenced the level of GDP per capita and within-country income inequality...

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...

We quantify the effect of foreign investment on productivity of acquired firms using a new firm-level database that tracks foreign ownership changes. To control for endogenous selection on unobserved firm-level characteristics, we study the differential impact of majority and minority foreign...

We estimate a multi-country multi-sector New Keynesian model to quantify the drivers of domestic inflation during 2020-2023 in several countries, including the United States. The model matches observed inflation together with sector-level prices and wages. We further measure the relative...
