The problem is formulated as a stochastic control problem with certain types of delay in the system. The objective is to choose trading and consumption strategies so that the expected discounted utility is maximized for an agent in the cases of finite and infinite populations. We first derive solutions to the associated Hamilton-Jacobi-Bellman equations, and then establish the optimal trading and consumption strategies in the games, and finally make comparisons with the classical Merton solutions.
