  This paper presents data of medical choices determining physicians’ profit and patients’ health benefit under three levels of market competition: monopoly, duopoly, and quadropoly. The data was collected from 136 German university students in an incentivised laboratory experiment. The designed experimental parameters and the formula for computing the payoff matrices of the games are described in this paper as well. This data was analyzed by Ge and Godager (2020) who employed generalized multinomial logit models to investigate the relationship between market competition and determinism in behavior under a quantal response equilibrium paradigm. This data contributes to future investigation on alternative game theoretic equilibrium concepts and the development of empirical methods for studying strategic choice behavior.

  Quantal response equilibrium choice (QREC) models are structural behavioral models that account for bounded rationality and strategic interactions in analyses of games where each player’s payoff is a vector. We revisit the question of how market competition affects pro-social behavior and fit a QREC model to data from an incentivized laboratory experiment, where the participants make decisions on medical treatment for abstract patients in monopoly, duopoly and quadropoly games. Our results demonstrate that competition can cause substantial behavioral responses without any changes in pro-social preferences if one allows for the possibility that competition influences the degree of randomness in decision-making. We find that a QREC model with fixed preference parameters provides precise out-of-sample predictions of behavior in games with vector payoffs. A Monte Carlo study is performed to show that the two-step estimator is accurate.
