Many papers have reported behavioral biases in belief formation that come on top of standard game-theoretic reasoning. We show that the processes involved depend on the way participants reason about their beliefs. When they think about what everybody else or another "unspeci fied" individual is...

The study analyzes data from world cup cross-country skiing sprint elimination tournaments for men and women in 2015-2020. In these tournaments prequalified athletes sequentially choose in which of five quarterfinal heats they want to compete. Due to a time constraint on the day the tournament...

We test experimentally an explanation of over and under confidence as motivated by (perhaps unconscious) strategic concerns, and find compelling evidence supporting this hypothesis in the behavior of participants who send and respond to others ́statements of confidence about how well they have...

Two individuals are involved in a conflict situation in which preferences are ex ante uncertain. While they eventually learn their own preferences, they have to pay a small cost if they want to learn their opponent's preferences. We show that, for sufficiently small positive costs of information...

We study experimentally persuasion games in which a sender (e.g., a seller) with private information provides verifiable but potentially vague information (e.g., about the quality of a product) to a receiver (e.g., a buyer). Various theoretical solution concepts such as sequential equilibrium or...

We run an experiment on the impact of involvement and outcome favorability on the acceptance of collective decisions. It involves 763 students at the Poznan University of Economics and Management. The collective decision chooses one out of four projects to improve students' study conditions. We...

The “freemium” model for digital goods involves selling a base version of the product for free, and making premium product features available to users only on payment. The success of the model is predicated on the ability to profitably convert free users to paying ones. Price promotions (or...

In 2020, gamers spent more than $15 billion on loot boxes, lotteries of virtual items in video games. Loot boxes are contentious. Regulators argue they constitute gambling, while game producers maintain they complement gameplay. In a prototypical mobile puzzle game we show that gameplay...
