This paper poses and tests relationships between local spatial variability of rainfall and property rights, as well as the degree of hierarchy, across 41 different tribal societies in Sudan. The authors find that there is a significant negative relationship between rainfall variability and degree of hierarchy. They also find that in the presence of local rainfall variability in Sudan, members of a tribe are more likely to establish common property institutions that allow access to all members.

This study investigates previous findings that indicate precolonial centralization was beneficial for development in Africa. Using new survey data from public primary schools, the author shows that the failure of leaders of centralized regions to comply with federal regimes was punished with underinvestment in public infrastructure services, hindering development and limiting access to these services in recent populations. The author proposes that the extent to which precolonial centralization was beneficial for development in Africa is mediated by compliance of the local governing bodies with federal regimes.

This study examines the relationship between political participation and warfare, suggesting that checks on power, removal of leaders, extent of political participation, and absence of fission will be negatively associated with the frequency of warfare. This hypothesis was supported with empirical analysis.

In this article, the author departs from previous research on common vs. private property ownership predictors to understand why ocean property rights often play out differently than land. As opposed to the dominant hypothesis that common property regimes will change to private property when resources are scarce and population increases, the author proposes economic defendability (the relationship between the value of the property and the cost to defend it) as a better predictor of property regime type.

This paper seeks to understand how the conflict resolution strategies of indigenous and non-indigenous groups differ in their efficacy. The authors suggest that indigenous methods of conflict resolution are more effective than non-indigenous methods by demonstrating that subjects from the Outline of Cultural Materials (OCM) associated with indigenous conflict management (ICM) will co-occur less frequently with OCM terms related to conflict than subjects related to non-ICM. They tested this by selecting OCM subjects that they felt best represented ICM, non-ICM, and instances of conflict and using chi-square tests to show how often these subjects co-occurred. They subsequently split up the "conflict" variable into four forms of conflict in order to show whether any of these forms might be more frequently found associated with ICM or non-ICM subjects. The results showed that conflict subjects were more likely to co-occur with non-ICM subjects, and that sociocultural/interpersonal conflicts were more likely to be associated with ICM subjects, whereas political conflicts were more likely to be associated with non-ICM subjects.

This study focuses on the factors associated with the development and persistence of an ideology of male supremacy. Authors identify several realms of culture that show a clear male preference and suggest that warfare is the most significant cause of the male supremacy complex in preindustrial societies. Authors hypothesize that warfare will be positively related to female infanticide. Results support this hypothesis. Another hypothesis relating diet to warfare and infanticide is provided, but not tested.

An early cross-cultural study that sought to establish correlations between "stages" of economic culture and a variety of different social and political institutions, such as form of government and justice, marriage and kinship, and behaviors during warfare.

This article examines causes of political participation in pre-industrial societies, particularly the level of resources and organization of resources. Hirschman’s concepts of exit, voice, and loyalty are also discussed. A distinction is made between range of community decision-making and the degree of adult involvement. Results from a multiple regression analysis favor the more structural variables (i.e. organization of resources) in the prediction of political participation.

This article investigates commonly accepted theories that purport to explain political centralization and investigate their relevance to sub-Saharan Africa. The leading ideas for the formation of political centralization using a worldwide sample include population density, inter-state warfare, and trade. However, the authors reported these factors are not predictive of the sub-Saharan Africa sample. The authors suggest that the lack of agricultural productivity in sub-Saharan Africa may have stunted population density therefore inhibiting political centralization and that Africa’s poor economic performance is, in part, due to lack of political centralization.

This study follows the theoretical construct of general cultural tightness and looseness (TL). Tightness is thought to be adaptive when facing socioecological threat, such as resource stress, since it involves a greater amount of cooperation. The study asks: "Why do some societies have relatively standardized or uniform clothing and adornment, whereas others have considerable variability across individuals?", which is connected to the broader question of why some societies show more within-group variation. The authors use a sample of 80 non-industrial societies from SCSS, to explore the relationship between general cultural tightness and standardization or synchrony in dress. The results support that tighter societies have more uniformity in dress and that resource stress is a predictor of synchrony. However, it is not supported that egalitarian societies have more synchrony, and that tightness is positively predicted by resource stress.
