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.

The second and third parts of this book classify the economic systems of foraging and agricultural societies in the SCCS based on correlations between their institutions of property an distribution. These economic types are then examined for relationships with other social, political, demographic, and environmental factors in order to draw tentative conclusions regarding the origins of the Agricultural and Industrial Revolutions. The fourth part of the book uses cross-national data to examine similar associations in industrial/service economies, and is not included here.

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.

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 paper investigates five different economic types of foragers: classic, transitional system, politically oriented, economically oriented, and intangibles-oriented. The author asserts that these economic types “are not mere epiphenomena of the oft-discussed social structural or political forces but, rather, are special characteristics that must be independently taken into account” (418). A myriad of environmental, subsistence, political, and social variables are examined: some differed significantly across the five economic types of foragers, but others such as famine threat, conflict, locational fixity, marital form, and postmarital residence did not differ between types.

This article suggests that Spiro's (1965) study on typology of social structure used a biased cross-cultural sample and possibly obscured regional patterns in data. Hypotheses related to marital structure, descent rules, food production and social stratification are tested.

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.

While it is widely accepted that there are a multitude of variables that contribute to a society’s level of democracy, the authors of this study argue that the prevalence of consanguinity is one that is often overlooked. Using a sample of 70 nations, they tested the relationship between consanguinity (defined as marriage and subsequent mating between second cousins or closer relatives) and level of democracy (defined by both the Polity IV scale and the EIU Index) and found a significant negative relationship. Similarly, when controlled for a host of different variables in multiple regression analysis, the significant relationship between consanguinity and level of democracy held true.

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 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.
