This paper experimentally investigates how concerns for social approval relate to intrinsic motivations to purchase ethically. Participants state their willingness-to-pay for both a fair trade and a conventional chocolate bar in private or publicly. A standard model of social image predicts that...

We analyze the political economy of the public provision of private goods when individuals care about their social status. Status concerns motivate richer individuals to vote for the public provision of goods they themselves buy in markets: a higher provision level attracts more individuals to...

Cartels can severely harm social welfare. Competition authorities introduced leniency rules to destabilize existing cartels and hinder the formation of new ones. Empirically, it is difficult to judge the success of these measures because functioning cartels are unobservable. Existing...

During the COVID-19 pandemic, the introduction of mandatory face mask usage triggered a heated debate. A major point of debate is whether community use of masks creates a false sense of security that would diminish physical distancing, counteracting any potential direct benefit from masking. We...

Using a laboratory experiment, we present first evidence that social image concerns causally reduce the take-up of an individually beneficial transfer. Our design manipulates the informativeness of the take-up decision by varying whether transfer eligibility is based on ability or luck, and how...

This paper uses a controlled laboratory experiment to investigate the effect of wealth on individual social responsibility (ISR), defined as choosing a more socially responsible product if a cheaper alternative is available. We find that rich consumers are significantly less likely to engage in...

This paper sheds new light on the role of communication for cartel formation. Using machine learning to evaluate free-form chat communication among firms in a laboratory experiment, we identify typical communication patterns for both explicit cartel formation and indirect attempts to collude...

The experimental literature on antitrust enforcement provides robust evidence that communication plays an important role for the formation and stability of cartels. We extend these studies through a design that distinguishes between innocuous communication and communication about a cartel,...
