Pigou (1920) advocated for taxes, set equal to marginal damages, on goods produced and consumed that involve negative externalities. Samuelson (1954) laid out the conditions for optimal pure public goods provision, but noted that free-riding (the “demand revelation” problem) was likely to...

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...

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...

Cartels are inherently instable. Each cartelist is best off if it breaks the cartel, while the remaining firms remain loyal. If firms interact only once, if products are homogenous, if firms compete in price, and if marginal cost is constant, theory even predicts that strategic interaction...

Providing public goods is hard, because providers are best off free-riding. Is it even harder if one group's public good is a public bad for another group or, conversely, gives the latter a windfall profit? We experimentally study public goods provision embedded in a social context and find that...

We study the effect of voting when insiders' public goods provision may affect passive outsiders. Without voting insiders' contributions do not differ, regardless of whether outsiders are positively or negatively affected or even unaffected. Voting on the recommended contribution level enhances...

Public goods are dealt with in two literatures that neglect each other. Mechanism design advises a social planner that expects individuals to misrepresent their valuations. Experiments study the provision of the good when preferences might be non-standard. We introduce the problem of the...

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...
