In empirical analyses of games, preferences and beliefs are typically treated as independent. However, if beliefs and preferences interact, this may have implications for the interpretation of observed behavior. Our sequential social dilemma experiment allows us to separate different interaction...

We elicit the willingness to sell personal data (contact information, Facebook details, preferences) in laboratory experiments, using a BDM and take-it-or-leave-it offers. Our experiments are novel in that (i) the experiments are incentivized, (ii) the focus on privacy issues is salient, and...

In a Bertrand-oligopoly experiment, firms choose whether or not to engage in cartel-like communication and, if so, they may get fined by a cartel authority. We find that four-firm industries form cartels more often than duopolies because they gain less from a hysteresis effect after cartel...

We explore whether lawful cooperation in buyer groups facilitates collusion in the product market. Buyer groups purchase inputs more economically. In a repeated game, abandoning the buyer group altogether or excluding single firms constitute credible threats. Hence, in theory, buyer groups...

We study the voluntary revelation of private information in a labor-market experiment where workers can reveal their productivity at a cost. While rational revelation improves a worker's payoff, it imposes a negative externality on others and may trigger further revelation. Such unraveling can...

An allocation rule that prioritizes registered donors increases the willingness to register for organ donation, as laboratory experiments show. In public opinion, however, this priority rule faces repugnance. We explore the discrepancy by implementing a vote on the rule in a donation experiment,...

One key problem regarding the external validity of laboratory experiments is their duration: while economic interactions out in the field are often lengthy processes, typical lab experiments only last for an hour or two. To address this problem for the case of both symmetric and asymmetric...

We analyze the impact of product bundling in experimental markets. One firm has monopoly power in a first market but competes with another firm à la Cournot in a second market. We compare treatments where the multi-product firm (i) always bundles, (ii) never bundles, and (iii) chooses whether...

We analyze the effects of cartel policies on firm behavior using data from the German power-cable cartel. Antitrust authorities affected the cartel under two different legal regimes: penalizing the cartel in some years, and exempting it for ten years from the general cartel prohibition. While...

When an upstream monopolist supplies several competing downstreamfirms, it may fail to monopolize the market because it is unable to commit not to behave opportunistically. We build on previous experimental studies of this well-known commitment problem by introducing communication. Allowing the...
