Does culture, and in particular religion, exert an independent causal effect on long-term economic growth, or do culture and religion merely reflect the latter? We explore this issue by studying the case of Protestantism in China during the late nineteenth and early twentieth centuries....

We find a U-shaped relation between happiness and religiosity in cross-country panel data after controlling for income levels. At a given level of income, the same level of happiness can be reached with high and low levels of religiosity, but not with intermediate levels. A rise in income causes...

Is it true that the Catholic reaction to Protestantism—the Counter-Reformation—lead to scientific and economic decline for hundreds of years? Introducing biography-based evidence, I show that Catholic and Protestant European cities long shared comparable trends of scientists per capita. But...

To identify effects of science on growth in the long-term, we need a shock to science which is sufficiently persistent. Was the Counter-Reformation—the Catholic reaction to Protestantism—such a shock? Did it harm science, unintentionally but enduringly, and thereby depress economic growth,...

In their survey of the literature on ethnic fractionalization and economic performance, Alesina and La Ferrara (JEL 2005) identify two main directions for future research. One is to improve the measurement of diversity and the other to treat diversity as an endogenous variable. This paper tries...

We use factor analysis to derive a robust measure of religiosity from items reported in five waves of the World Value Survey. Our measure of religiosity is negatively correlated with per capita income. Development apparently causes religiosity to fall to about half its pre-modern level. Most...

Does fractionalization change over (short periods of) time? If so, are there any substantial implications for economic performance? To answer such questions, we construct a new panel data set with measures of fractionalization for 26 former communist countries covering the period from 1989 to...

This paper ia an attempt to clarify the relationship between fractionalization, polarization and conflict. The literature on the measurement of ethnic diversity has taken as given that the proper measure for heterogeneity can be calculated by using the fractionalization index. This index is...
