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 …
