This paper revisits and critically reevaluates the widely-accepted modernization hypothesis which claims that per capita income causes the creation and the consolidation of democracy. We argue that existing studies find support for this hypothesis because they fail to control for the presence of...

This paper studies empirically the effects of and the interactions amongst economic and political liberalizations. Economic liberalizations are measured by a widely used indicator that captures the scope of the market in the economy, and in particular of policies towards freer international...

In an 80-country panel since the 1960s, the convergence rate for per capita GDP is around 1.7% per year. This "beta convergence" is conditional on an array of explanatory variables that hold constant countries' long-run characteristics. The introduction of country fixed effects generates a much...

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...

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...

We consider a tractable model of heterogeneous production units that features endogenous entry and productivity investment to assess the quantitative impact of policy distortions on aggregate output and establishment size. Relative to the standard factor misallocation framework, policy...

There is tremendous variation in conflict intensity both across and within civil conflict spells. Using an instrumental variables approach and a rich set of dynamic, empirical models, we find that the intensity of conflict is negatively related to per-capita income. Economic conditions also...

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...

Nutrition is a key input in the health production function, and a better understanding of how we eat can aid in guiding effective policy change towards better population health. This study documents prevalence rates, trends in, and potential correlates of nutrient intake for panels of countries,...

This paper uses an updated and revised panel data set on ambient air pollution in cities world-wide to examine the robustness of the evidence for the existence of an inverted U-shaped relationship between national income and pollution. We test the sensitivity of the pollution-income relationship...
