Abstract

High levels of generalized trust are usually associated with economic growth and lower transaction costs, while heterogeneous populations have been linked to lower levels of trust. As societies are rapidly diversifying on many fronts, it is important to investigate the relationship between heterogeneity and trust so that policymakers can respond appropriately. Research on this topic commonly uses fractionalization indices. In this paper, we develop a new Fractionalization Index of National Origin (FINO) to capture contemporary heterogeneity. We then conduct a two-step hierarchical logit regression analysis on contemporary data, including over 40,000 observations from 23 EU countries. Our results indicate that both fairness and heterogeneity are significant predictors of generalized trust in the EU. We theorize that the relationship between heterogeneity and generalized trust may be context-dependent, becoming relevant only once countries have established a certain level of fairness.
