study the impact of different time horizons on cooperation in (quasi) continuous time prisoner's dilemmas. We find that … cooperation levels are similar or higher when the horizon is deterministic rather than stochastic. Moreover, a deterministic … deterministic horizon subjects show high initial cooperation and a strong end-of-period reversal to defection. Moreover, they do not …

Although punishment is thought to be a key mechanism, evolutionary game theory has … revealed that the simplest form of punishment called peer punishment is useless to solve the dilemma, since peer punishment … itself is costly. In the literature, more complex types of punishment, such as pool punishment or institutional punishment …

We use skin conductance responses and self-reports of hedonic valence to study the emotional basis of cooperation and … punishment in a social dilemma. Emotional reaction to free-riding incites individuals to apply sanctions when they are available …. The application of sanctions activates a "virtuous emotional circle" that accompanies cooperation.
