High Effort

We propose a dual selves model to integrate affective responses and belief-dependent emotions into game theory. We apply our model to team production and model a worker as being composed of a rational self, who chooses effort, and an emotional self, who expresses esteem. Similar to psychological game theory, utilities depend on beliefs, but only indirectly. More concretely, emotions affect utilities, and the expression of emotions depends on updated beliefs. Modeling affective responses as actions chosen by the emotional self allows us to apply standard game-theoretic solution concepts. The model reveals that with incomplete information about abilities, workers only choose high effort if esteem is expressed based on interpersonal comparisons and if the preference for esteem is a status preference.

Performance Enhancing

We revisit the performance-enhancing drug game by applying models of guilt aversion and reciprocity. Both models fit within the framework of psychological game theory in that they allow payoffs to depend on beliefs. We explore the extent to which social norms can help reduce or eliminate doping in sport. With reciprocity, we see that first-order beliefs on the prevalence of doping are key and a norm of clean sport would require a coordinated shift in such beliefs. With guilt aversion, by contrast, second-order beliefs are key and individuals may have an incentive to race clean even if they expect competitors will dope. Our results point to the importance for sports bodies and coaches to manage the beliefs of athletes.
