"This paper presents the Global Preference Survey (GPS), the first global survey focused on measuring a set of fundamental economic preferences: risk preference, time preference, positive and negative reciprocity, altruism, and trust. The paper shows that these preferences differ substantially across countries, but heterogeneity within countries is even more pronounced. The preferences vary systematically with plausibly exogenous individual characteristics – gender, cognitive ability, age, and cultural differences as captured by language structure – as well as country-level characteristics like geography. " Figures 2 and 3 are very interesting.
