Abstract

We establish the existence and uniqueness of solutions to a mean-field reflected backward stochastic differential equation with an infinite horizon under a Lipschitz condition on the coefficient. As an application, we prove the existence of an optimal strategy for the mean-field mixed stochastic control problem.
