Nighttime lights data are a measure of economic activity whose error is plausibly independent of the measurement errors of most conventional indicators. Therefore, we can use nighttime lights as an independent benchmark to assess existing measures of economic activity (Pinkovskiy and...

With populations aging and the epidemic of obesity spreading across the globe, global health risks are shifting toward non-communicable diseases. Innovative biomarker data from recently conducted population-representative surveys in lower, middle and higher income countries are used to describe...

We measure and examine data error in health, education and income statistics used to construct the Human Development Index. We identify three sources of data error which are due to (i) data updating, (ii) formula revisions and (iii) thresholds to classify a country's development status. We...

We present evidence on the differences in the intensity with which ten major technologies are used in 185 countries across the world. We do so by calculating how many years ago these technologies were used in the U.S. at the same intensity as they are used in the countries in our sample. We...

We study the joint dynamics of economic and political change. Predictions of the simple model that we formulate in the paper get considerable support in a panel of data on political regimes and GDP per capita for about 150 countries over 150 years. Democratic capital -- measured by a nation's...

Poor countries are more volatile than rich countries, and we know this volatility impedes their growth. We also know that commodity price volatility is a key source of those shocks. This paper explores commodity and manufactures price over the past three centuries to answer three questions: Has...

This paper presents a model where human capital differences - rather than technology differences - can explain several central phenomena in the world economy. The results follow from the educational choices of workers, who decide not just how long to train, but also how broadly. A quot;knowledge...

The rise in world trade since 1970 has raised international mobility of labor services. We study the effect of such a globalization of the world's labor markets. We find that when people can choose between wage work and managerial work, the output gains are U-shaped: A worldwide labor market...

We propose a model of sovereign debt where countries vary in their level of financial development, defined as the extent to which countries can hedge rare disasters in international capital markets. We show that low levels of financial development generate the “debt intolerance” phenomenon...

In this paper we revisit the relationship between institutions, human capital and development. We argue that empirical models that treat institutions and human capital as exogenous are misspecified both because of the usual omitted variable bias problems and because of differential measurement...
