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 article uses factor analysis to identify the key variables underlying the many cross-cultural associations reported by Textor (1967). Twelve factors are identified.

Considerable disagreement exists in regard to the origin and distribution of economic phenomena such as money, slavery, markets, exchange, and imbalanced transfers. Here the author utilizes a worldwide cross-cultural sample of 60 pre-industrial "societies" to empirically test many economic hypotheses, with a focus on distributional mechanisms and institutions.

The author evaluates predictions from the standard model of intensification of food production and suggests it be rejected based on an analysis of 40 societies. The standard model proposes that food producers will increase their energy input until the maximum possible output is achieved, at which point output and labor productivity will fall and producers will invent or adopt new technologies. He then proposes a different model, which he terms the cultural niche construction model. The cultural niche construction model proposes that societies will minimize their energy input while maximizing their returns through continual technological adaptation and niche construction. After predictions from this second model are tested, the author suggests tentatively accepting the cultural niche construction model as a new framework to explain transitions to complex societies.

The author examines modes of marriage and societal organization from a functionalist (general evolutionary) perspective. He focuses on the relationships of subsistence (economic) patterns, settlement patterns, and social complexity to predicting modes of marriage, with particular emphasis on the importance of subsistence as an underlying structural influence upon social patterns.

This exploratory study seeks to explain cassava production and processing in Africa by considering cultural, agronomic, and environmental data. After examining the descriptive results of the agricultural and social contexts of cassava use, the authors build upon Boserup's population density model (1965) to analyze their own hypothesized model of cassava's importance among the sampled societies.

This article investigates residence, descent rules, and family structure. Empirical analysis suggests that they are associated with settlement patterns, particularly economic and demographic variables.

The present study aims to evaluate correlations of private property from two of Murdock's datasets, one of 147 societies (1981) and the other of 312 societies (1967). Altogether the author tested 146 variables coded by Murdock against variables regarding the ownership of land and of movables drawn from Murdock (1967), Simmons (1937), and Swanson (1960). In total, there were 51 statistically significant correlations between private property ownership and other variables. Additionally, the author summarizes the results from this article and the two that preceded it stating that throughout all of the correlations he ran, the practice of agriculture, the use of cereal grains, and the presence of castes and classes were the only variables that predicted private property in all of the datasets that were utilized.

Authors investigate the cross-cultural correlates of games of chance. They advance a "conflict-enculturation" model to explain why individuals choose to engage in games of chance in particular (as opposed to games of strategy or physical skill). They suggest that games of chance are linked to cultures with antecedent conflict and/or feelings of powerlessness in the presence of uncertainty; both are psychological stressors whose effects may be assuaged by play with uncertainty models in the form of games of chance.

This article posits that nuclear, independent families are more common under certain economic conditions that affect food supply, demand for family labor, physical mobility, and property system. Empirical analysis suggests that nuclear, independent families are associated with hunting and gathering subsistence type and low social stratification.
