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...

As we have demonstrated in a recent laboratory experiment [see Sebald and Walzl (2012)], individuals tend to sanction others who subjectively evaluate their performance whenever this assessment falls short of the individual's self-evaluation even if their earnings are unaffected by the...

We conduct a laboratory experiment with agents working on and principals benefitting from a real effort task in which the agents' performance can only be evaluated subjectively. Principals give subjective performance feedback to agents and agents have an opportunity to sanction principals. In...

Recent studies find ample evidence that monetary and immaterial gifts influence effort in the workplace. We investigate the impacts of monetary gift exchange and of expressions of respect on salespersons' reciprocity when purchasing doner durum, a common lunch snack. Prior to the food's...

In division problems with entitlements, we investigate whether fairness concerns overrule strategic behavior and inhibit full use of the decision-making power. In a lab experiment where entitlements are derived from costly contributions, we vary bargaining power by using either the majority rule...

A debate among practicing managers is whether to use cooperative or competitive incentives for team production. While competitive incentives may drive individual effort higher, they may also lead to less help and more sabotage; an issue exacerbated when team members' abilities are varied. Using a...

Incentivized experiments in which individuals receive monetary rewards according to the outcomes of their decisions are regarded as the gold standard for preference elicitation in experimental economics. These task-related real payments are considered necessary to reveal subjects' "true...

Large, macroeconomic shocks in the past have been shown to influence economic decisions in the present. We study in an experiment with 743 subjects whether small-scale, seemingly negligible, events also affect the formation of risk preferences. In line with a reinforcement learning model, we...

Reciprocation of monetary gifts is well-understood in economics. In contrast, there is little research on reciprocal behavior following immaterial gifts like compliments. We close this gap and investigate how employees reciprocate after receiving immaterial and material gifts. We purchase (1)...

Peoples' willingness to vaccinate is critical to combating the COVID-19 pandemic. We devise a representative experiment to study how the design of the vaccine approval procedure affects public attitudes towards vaccination. Compared to an Emergency Use Authorization, choosing the more thorough...
