This research advances the hypothesis and establishes empirically that interpersonal population diversity has contributed significantly to the emergence, prevalence, recurrence, and severity of intrasocietal conflicts. Exploiting an exogenous source of variations in population diversity across...

This research advances the hypothesis and establishes empirically that interpersonal population diversity, rather than fractionalization or polarization across ethnic groups, has been pivotal to the emergence, prevalence, recurrence, and severity of intrasocietal conflicts. Exploiting an...

We present new evidence on the influence of income inequality on generalized trust. Using individual panel data from Swedish counties together with an instrumental variable strategy we find that differences in disposable income, and especially differences among people in the bottom half of the...

We conduct an extensive robustness analysis of the relationship between trust and growth for a later time period (the 1990s) and with a bigger sample (63 countries) than previous studies. In addition to robustness tests that focus on model uncertainty, we use Least Trimmed Squares, a robust...

We present new evidence on how generalized trust is formed. Unlike previous studies, we look at the explanatory power of economic institutions, we use newer data, we incorporate more countries, and we use instrumental variables to handle the causality problem. A central result is that legal...

We explore the evolution of the structure and performance of a social network in a population of individuals who search for local optima in diverse and dynamic task environments. Individuals choose whether to innovate or imitate and, in the latter case, from whom to learn. The probabilities of...

Values are to a society what character is to a person: it reveals his true inner self, yet is difficult to describe in exact terms. Moreover, a person's character may show in his actions in various, sometimes contradictory ways so that it may be difficult to induce a person's character from his...

We explore the links between trust and a broad range of financial structure and development measures. Our base sample is a cross section of 48 countries and the analysis covers the period 1980-1994. We use a new World Bank data set that provides the most comprehensive coverage of financial...

This paper determines how individual, relative to community, social capital affects individual migration decisions. We make use of nonpublic data from the Social Capital Community Benchmark Survey to predict multidimensional social capital for observations in the Current Population Survey. We...

Consistent with predictions from the literature, we find that higher levels of in-migration dilute multiple dimensions of a community's level of social capital. The analysis employs a 2SLS methodology to account for potential endogeneity of migration.
