We propose an approximation method for analyzing Ericson and Pakes (1995)-style dynamic models of imperfect competition. We develop a simple algorithm for computing an "oblivious equilibrium," in which each firm is assumed to make decisions based only on its own state and knowledge of the long...

Many contemporary economists portray Smith's quot;perfect libertyquot; as a precursor of perfect competition. However, modern perfect competition, particularly post World War II mathematical general equilibrium models, are far removed from meaning and intent of Smith's quot;natural system of...
