Dynamic oligopoly with sticky prices: Closed-loop, feedback, and open-loop solutions

We investigate a dynamic oligopoly game with price adjustments. We show that the subgame perfect equilibria are characterized by larger output and lower price levels than the open-loop solution. The individual (and industry) output at the closed-loop equilibrium is larger than its counterpart at the feedback equilibrium. Therefore, firms prefer the open-loop equilibrium to the feedback equilibrium, and the latter to the closed-loop equilibrium. The opposite applies to consumers.
