Working with a sample of individuals from 43 countries, including some of the most and least corrupt in the world, we run an experiment in which: `private citizens` have to decide whether and how much to offer `public servants` in exchange for corrupt services; `public servants` have to decide...

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...

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...

Previous analyses of the formation and composition 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 quasi-experiment in which villages were formed by government officials selecting...

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...

Using data from a field experiment conducted in seventy Colombian municipalities, we investigate who pools risk with whom when risk pooling arrangements are not formally enforced.  We explore the roles played by risk attitudes and network connections both theoretically and empirically.  We...

Economists have traditionally assumed that individual behavior is motivated exclusively by extrinsic incentives.  Social physchologists, in contrast, stress that intrinsic motivations are also important.  In recent work, economic theorists have started to build psychological factors, like...

This paper describes and analyzes the results of a unique field experiment especially designed to test the effects of the level of commitment and information available to individuals when sharing risk.  We find that limiting exogenously provided commitment is associated with less risk sharing,...

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

Using a specially designed lab-type experiment conducted in the field, we compare the willingness of head teachers, centrally appointed public servants, and community representatives to hold Ugandan primary school teachers to account.  We find no difference in the willingness of centrally...
