We investigate whether the set of available enforcement mechanisms affects the formation of risk sharing relations by applying dyadic regression analysis to data from a specifically designed behavioural experiment, two surveys and a genealogical mapping exercise. During the experiment...

Previous analyses of the formation and comparison of community based organizations (CBOs) have used cross section data. So, causal inference has been compromised. We obviate this problem by using data from a quai-experiment in which villages were formed by government officials selecting and...

Assortative matching occurs in many social contexts. We experimentally investigate gender assorting in sub-Saharan villages. In the experiment, co-villagers could form groups to share winnings in a gamble choice game. The extent to which grouping arrangements were or could be enforced and,...

Using original survey data on beneficiary assessment, we examine the performance of the NGO sector in Uganda. In general satisfaction with NGO intervention is high. We find evidence that NGOs endeavour to redress the balance between rich and poor communities but also that NGOs neglect isolated...

Using original survey data, we document the activities, resources, and governance structure of NGOs operating in Uganda. The NGO sector is funded primarily by international non-governmental organizations and bilateral donors. We Þnd large differences in size and funding across NGOs, with only a...

Using a simple one-shot bribery game, we find evidence of a negative externality effect and a framing effect. When the losses suffered by third parties due to a bribe being offered and accepted are increased bribes are less likely to be offered and accepted. And when the game is presented as a...

Using a simple one-shot bribery game, we find evidence of a negative externality effect and a framing effect. When the losses suffered by third parties due to a bribe being offered and accepted are high and the game is presented as a petty corruption scenario instead of in abstract terms bribes...

This paper explores two hypotheses concerning the role of status in relationships between rich and poor in traditional communities by analyzing who goes to whose funerals in six Zimbabwean villages. Funerals allow status to be observed because non-attendance is a sign of disrespect. We find that...

Econometric analyses of European datasets suggest that income aspirations increase with current income. This finding is consistent with the adaptation hypothesis - the notion that individual aspirations adjust to reflect personal circumstances and living conditions. We add to these existing...

Data from three bargaining games-the Dictator Game, the Ultimatum Game, and the Third-Party Punishment Game-played in 15 societies are presented. The societies range from US undergraduates to Amazonian, Arctic, and African hunter-gatherers. Behaviour within the games varies markedly across...
