Abstract: We present evidence from a field experiment in an environment where competing parties can engage in conflict and the efforts they invest create no positive externalities. The experiment takes place in swimming pools. When all lanes are occupied, one of our actors joins the least crowded lane and asks one of the swimmers to move to a different one. The lane represents a contested scarce resource. We vary the actors’ valuation (high and low) for the good through the message they deliver. We take advantage of the natural variation in the number of swimmers and use it as a proxy for the scarcity of the resource. Consistent with theoretical predictions, a swimmer’s propensity to engage in conflict increases in scarcity and decreases in the actor’s stated valuation. We complement the analysis with survey evidence, which helps us understand and interpret the results. (Co-autors Loukas Balafoutas, Marco Faravelli, Roman M. Sheremeta)
Abstract: Understanding the roots of human cooperation among strangers is of great importance for solving pressing social dilemmas and maintening public goods in human societies. We study the development of cooperation in 929 young children, aged 3 to 6. In a unified experimental framework, we examine which of three fundamental pillars of human cooperation – direct and indirect reciprocity as well as third-party punishment – emerges earliest as an effective means to increase cooperation in a repeated prisoner's dilemma game. We find that third-party punishment exhibits a strikingly positive effect on cooperation rates by doubling them in comparison to a control condition. It promotes cooperative behavior even before punishment of defectors is applied. Children also engage in reciprocating others, showing that reciprocity strategies are already prevalent at a very young age. However, direct and indirect reciprocity treatments do not increase overall cooperation rates, as young children fail to anticipate the benefits of reputation building. We also show that the cognitive skills of children and the socioeconomic background of parents play a vital role in the early development of human cooperation.

Abstract: Norm-based accounts of social behavior are increasingly common in economics. In such accounts, behavior is seen as reflecting tradeoffs between maximization of own consumption utility and conformity to social norms. Theories of norm-following tend to assume a) that there exists a single, stable, commonly known injunctive social norm for a given choice setting and b) that each person has a stable propensity to follow social norms. In the first part of my talk, I report on work using panel data on 1468 participants aged 11-15 years old in Northern Ireland and Bogotá in which we measure norms and norm-following propensity twice at 10 weeks apart, and we show how to exploit variation in shared normative perceptions to extend our understanding of the extent to which norms are shared, stable, and can be predicted to change. In the second part of my talk, I report on studies that couple panel data with experimental or naturally occuring interventions that affect norms. These results identify interventions that can impact norm change and highlight the limitations of those interventions. I conclude with some thoughts on future research.
