Title: All Over the Map: Heterogeneity of Risk Preferences across Individuals, Prospects, and Countries

Abstract: "We analyze the risk preferences of 2939 subjects across 30 countries on all continents. Using structural modeling, we explore heterogeneity in risk preferences across three dimensions: i) between individuals; ii) between prospects; and iii) between countries. Preferences in non-Western countries differ systematically from those found in Western countries, hitherto considered universal. Reference-dependence and likelihood-dependence are both found to play a role in describing preferences. While we confirm previous results on individual characteristics explaining little of overall preference heterogeneity, between countries a few macroeconomic indicators can explain a considerable part of the heterogeneity. The heterogeneity explained furthermore differs across decision parameters, being low for pure risk aversion measures, but higher for measures of noise and for rationality parameters."
