Abstract
In understanding the relationship between inequality and trust across countries, it is also necessary to consider the effect of ethnic, religious and linguistic fractionalization. Using only high-quality inequality data, and a new dataset on fractionalization, I analyze a group of sixteen mostly OECD countries. Both inequality and fractionalization are negatively associated with trust, and when both are included in the model, inequality is the more significant factor. Using instrumental variables, I show that a one standard deviation increase in inequality (a 6 point rise in the gini) causes a 13 percentage point fall in trust. Both rich and poor people tend to be less trusting in unequal countries, and little of the effect seems to be related to crime.
