We extend the voluntarily separable repeated Prisoner's Dilemma (Fujiwara-Greve and Okuno-Fujiwara, 2009) to continuous actions. We show that there is a (constrained) efficient bimorphic equilibrium which is robust under evolutionary pressure. It consists of a cooperative strategy and a myopic defection strategy so that our model provides a foundation to incomplete information models as well.
