Revenue (IR), which is the equivalent of the Internal Revenue Service (IRS) in the United States.

Acemoglu, Johnson, and Robinson (2001) established that economic institutions today are correlated with expected mortality of European colonialists. David Albouy argues this relationship is not robust. He drops all data from Latin America and much of the data from Africa, making up almost 60 percent of our sample, despite much information on the mortality of Europeans in those places during the colonial period. He also includes a “campaign” dummy that is coded inconsistently; even modest corrections undermine his claims. We also show that limiting the effect of outliers strengthens our results, making them robust to even extreme versions of Albouy's critiques.

Existing studies establish a strong cross-country correlation between income and democracy but do not control for factors that simultaneously affect both variables. We show that controlling for such factors by including country fixed effects removes the statistical association between income per capita and various measures of democracy. We present instrumental-variables estimates that also show no causal effect of income on democracy. The cross-country correlation between income and democracy reflects a positive correlation between changes in income and democracy over the past 500 years. This pattern is consistent with the idea that societies embarked on divergent political-economic development paths at certain critical junctures.
