Using experimental surveys as a primary source, Kim and Kim compare a wide range of developed countries to assess the determinants of generalized social trust. With data from Belgium, France, Italy, Japan, Singapore, South Korea, the Netherlands, and the United States, Kim and Kim present a detailed picture of trust at the individual level, across different ethnic groups, and across different regions with economic and cultural distinctions. They focus on a range of concepts, including generalized trust and familism; causal relationships among cultural values, particularized trust, and institutional trust at the individual level; and relationships between culture, wealth, and governance at the macro-level. In doing so, they consolidate substantial quantitative data with rigorous theoretical analysis and advance our understanding of social trust and prosociality in general. A valuable resource for researchers and advanced students in political science, sociology, and social psychology around the world.
