Fundraising for public goods by private contributions is often undermined by free-riding. One prominent mechanism suggested to alleviate problem of free-riding is a fixed-prize lottery with winning probabilities proportional to individual contributions (Morgan, 2000; Morgan and Sefton, 2000). Yet,...

Intentions play a fundamental role in many situations characterized by nonsimultaneous interaction from principal-agent settings in firms to the international task of protecting the environment and the climate. We experimentally investigate how decision makers (DMs) respond to perceived...

Social comparison feedback, i.e. informing people about the behavior of others, has been shown to influence prosocial behavior in many domains, including tax compliance and energy conservation. We argue that heterogeneity in people's (un)willingness to consult the corresponding information...

In sequential interactions, both the first mover's intention and the outcome of his choice may influence the second mover's action. While outcomes are typically observable, intentions are more likely to be hidden, leaving potential wiggle room for the second mover when deciding on a...

We study cheating as a collective-risk social dilemma in a group setting in which individuals are asked to report their actual outcomes. Misreporting their outcomes increases the individual’s earnings but when the sum of claims in the group reaches a certain threshold, a risk of collective...

We investigate how the transparency of selecting an agent for a task affects the agent's reciprocal behavior. In a laboratory experiment, we conduct a gift-exchange game with a random move representing the chance that a selected agent may not be available. We vary the transparency of the...

This paper examines the distributional consequences of public debt reduction achieved through spending cuts. Under the assumption that public goods and transfers are relatively more valuable to the poor, our calculations indicate that the elderly poor stand to lose from such policies. Debt...

The exogenous manipulation of choice architectures to achieve social ends ('social nudges') can raise problems of effectiveness and ethicality because it favors group outcomes over individual outcomes. One answer is to give individuals control over their nudge ('self-nudge'), but the trade-offs...

We test whether a descriptive norm-nudge is a suitable policy tool to increase cooperation in a social dilemma when decisions are taken by teams, not individuals. 10 Each team in our experiment comes from a different fishing boat at Lake Victoria, Tanzania. The provision of a norm-nudge is...

Policymakers discuss nudges as instruments to foster individual public good contributions. Contrary to the original aim of nudges, which is to improve decision outcomes for the individual, pro-social nudges aim to improve the social outcomes of individual behavior. This can potentially result in...
