By the mid-nineteenth century school enrollment rates in the United States exceeded those of any other nation in the world and by the early twentieth century the United States had accomplished mass education at all levels. No country was able to close the gap until the last quarter of the...

We use 1940 Census data to study the intergenerational transmission of human capital for children born in the 1920s and educated during an era of expanding but unequally distributed public school resources. Looking at the gains in educational attainment between parents and children, we document...

Electricity is a general purpose technology and the catalyst for the second industrial revolution. Developing countries are currently making huge investments in electrification, with a view to achieving structural change. What does history say about its impact on the structure of employment? We...

In a multiperiod investment framework, firms with high expected growth earn higher expected returns than firms with low expected growth, holding investment and expected profitability constant. This paper forms cross-sectional growth forecasts, and constructs an expected growth factor that yields...

A growing literature relies on natural experiments to establish causal effects in macroeconomics. In diverse applications, natural experiments have been used to verify underlying assumptions of conventional models, quantify specific model parameters, and identify mechanisms that have major...

Assigning a third party at the 75th percentile of the centrality distribution (as compared to the 25th) increases efficiency by 21% relative to the mean: we attribute 2/5 of the effect to monitoring and 3/5 to enforcement. The largest efficiency increase occurs when senders and receivers are...

This study examines how the economic effects of elections in rural China depend on voter heterogeneity, for which we proxy with religious fractionalization. We first document religious composition and the introduction of village-level elections for a nearly nationally representative sample of...
