We use a limited information environment to assess the role of confusion in the repeated voluntary contributions game. A comparison with play in a standard version of the game suggests, that the common claim that decision errors due to confused subjects biases estimates of cooperation upwards,...

A player׳s knowledge of her own actions and the corresponding payoffs may enable her to infer or form beliefs about what the payoffs would have been if she had played differently. For quantitative learning models employed in studies of low information environments, players׳ ex-post inferences...

Tax evasion may cause social welfare losses due to the incentives of taxpayers to invest in the concealment and of tax authorities to invest in the detection of tax evasion. Reducing the investment of both parties at the same time would then lead to a Pareto improvement. Given that concealment...

We investigate the effects of information feedback in rent-seeking games with two different contest structures. In the share contest a contestant receives a share of the rent equal to her share of rent-seeking expenditures, while in the lottery contest a contestant wins the entire rent with...

An extensive literature demonstrates the existence of framing effects in the laboratory and in questionnaire studies. This paper reports new evidence from a natural field experiment using a subject pool one might expect to be particularly resistant to such effects: experimental economists. We...

Microfinance programs provide poor people with small loans given to jointly liable self-selected groups. Follow-up loans provide incentives to repay. We experimentally investigate the influence of those features on strategic default. Each group member invests in an individual risky project,...

We report an experiment comparing sequential and simultaneous contributions to a public good in a quasi-linear two-person setting. In one parameterization we find that overall provision is lower under sequential than simultaneous contributions, as predicted, but the distribution of contributions...
