Economists long have argued that the severe sex imbalance that exists in many developing countries is caused by underlying economic conditions. This paper uses plausibly exogenous increases in sex-specific agricultural income caused by post-Mao reforms in China to estimate the effects of total...

This paper investigates the institutional causes of China's Great Famine. It presents two empirical findings: 1) in 1959, when the famine began, food production was almost three times more than population subsistence needs; and 2) regions with higher per capita food production that year suffered...

I first document that the introduction of the One Child Policy dramatically increased sex selection in certain regions, and that the Chinese government responded to this by allowing parents who had a daughter as their first child to try for a second child. Next, I show that the increase in...

This paper investigates the long-run effects of climate change on conflict by examining cooling from 1400-1900 CE, a period that includes most of the Little Ice Age. We construct a geo-referenced and digitized database of conflicts in Europe, North Africa, and the Near East from 1400-1900, which...

This paper estimates the effect of access to transportation networks on regional economic outcomes in China over a twenty-period of rapid income growth. It addresses the problem of the endogenous placement of networks by exploiting the fact that these networks tend to connect historical...

We study the relationship between geography and growth. To do so, we first develop a dynamic spatial growth theory with realistic geography. We characterize the model and its balanced growth path and propose a methodology to analyze equilibria with different levels of migration frictions. We...

We investigate the long term determinants of political and economic outcomes over a new data set composed of Mississippi counties. We analyze the effect of disfranchisement on voting registration at the end of the nineteenth century (1896-9), as well as the impact of voting registration on...

We study the evolution of racial educational inequality across US states from 1940 to 2000. We show that throughout this period, despite evidence of convergence, the racial gap in attainment between blacks and whites has been persistently determined by the initial gap. We obtain these results...
