We analyze an experimental public goods game in which group members can endogenously determine whether they want to supplement a standard voluntary contribution mechanism with the possibility of rewarding or punishing other group members. We find a large and positive effect of endogenous...

We report novel results from changes in the marginal per capita return (MPCR) in a one-shot public good game where participants make a single provision decision. Data was collected using three "data collection processes": an online experiment conducted on Prolific, an online experiment conducted...

This paper investigates how heterogeneity in contestants' investment costs affects the competition intensity in a dynamic elimination contest. Theory predicts that the absolute level of investment costs has no effect on the competition intensity in homogeneous interactions. Relative cost...

We investigate how heterogeneity in contestants' investment costs affects competition expenditures in a dynamic elimination contest with different seeding variants of contestants. Theory predicts that expenditures in dynamic contests are lower when competitors are heterogeneous than when they...

The paper reports an experimental study based on a variant of the popular Chinos game, which is used as a simple but paradigmatic instance of observational learning. There are three players, arranged in sequence, each of whom wins a fixed price if she manages to guess the total number of coins...

We examine behavior in one-shot appropriation games with deterministic and probabilistic degradation externalities, where the marginal net benefit from appropriation is endogenous, dependent on individuals' expectations of group appropriation. The experimental design involves a menu of games...
