Abstract: In this article, a dynamic industry with optimizing interacting firms is formulated as a Markov game. It is shown that a suitable specification of the state space and the interaction structure leads to constant optimal decisions or routine behavior of all firms. This result depends on two crucial assumptions, the homogeneity of the state space and the linearity of the payoff functions. These assumptions may be interpreted as one possibility to understand bounded rationality. Myopic expectations according to the entry-exit process lead to a similar result in the extended entry-exit model. Hence, neoclassical methods are merged with evolutionary terminology.
