There are many stories of democracy but little consensus over which variables robustly determine its emergence and survival. We apply extreme bounds analysis to test the robustness of 59 factors proposed in the literature, evaluating over 3 million regressions. The most robust determinants of...

In a series of papers, my colleagues and I have demonstrated that levels of per capita income, economic growth, and other economic and demographic dimensions are strongly correlated with geographical and ecological variables such as climate zone, disease ecology, and distance from the coast....

We exploit differences in the mortality rates faced by European colonialists to estimate the effect of institutions on economic performance. Our argument is that Europeans adopted very different colonization policies in different colonies, with different associated institutions. The choice of...

In a seminal contribution, Acemoglu, Johnson, and Robinson (2001) argue property-rights institutions powerfully affect national income, using estimated mortality rates of early European settlers to instrument capital expropriation risk. However 36 of the 64 countries in their sample are assigned...

This paper responds to findings by Acemoglu, Johnson and Robinson (2000) that suggest weak institutions, but not physical geography and correlates like disease burden, explain current variation in levels of economic development across former colonies. Using similar data and expanding the sample...
