This study presents a theory of land inheritance that "focuses on the incentives that land inheritence rules create for potential heirs" and tests this theory on a cross-cultural sample.

This article tests Randall Collin's 1975 theory that political-economic factors, rather than family/kinship factors, predict the degree of sexual stratification in a given society. A multivariate model is tested and findings contradict the theory.

This article presents a representative theoretical model of the transition to agriculture. Empirical results from a cross-cultural sample provide support for the model. Results suggest that agriculture is associated with population density, technological sophistication, environment, and proximity to agricultural hearths, such as the Fertile Crescent.

This article investigates the determinants of post marital residence, particularly female contribution to subsistence. This study suggests in contrast to previous research that female contribution to subsistence does predict residence if non-sororal polygyny, and internal warfare are controlled. Theoretical perspectives on how marriage system affects the relationship between residence and contribution to subsistence are discussed.

This article investigates how pathogen risk affects xenophobia, in-group bias, and collectivist and conformist values. Data analysis suggests that there is an association between pathogen risk and socialization for collectivist values, but the other variables were not associated with pathogen prevalence.

This study develops a model of the conditions under which a societies switch from a anarchy to a hierarchy. Empirical results suggest that the presence of police, technological sophistication, population density, and food storage are positively associated with the presence of a territorial hierarchy.

This study examines land ownership and territoriality among hunter-gatherers in relation to resource density and predictability and defense technology. A model is presented and briefly tested on a cross-cultural sample of 14 hunter-gatherer societies. Results suggest that societies in more resource-rich areas will be more territorial than societies in less resource-rich areas.
