From Walrasian Oligopolies to Natural Monopoly: an Evolutionary Model of Market Structure
We study a market for a homogeneous good in which firms adjust their production decisions on the basis of imitation, learning from own experience, and local experimentation. For any fixed set of firms (more than one), long run behaviour settles on a symmetric marginal-cost pricing equilibrium. When market entry and exit are allowed, we find a sharp effect of technology on long-run market structure. Specifically, we show that, under decreasing returns and some fixed cost, the market grows to "full capacity" at Walrasian equilibrium; on the other hand, if returns are increasing, the unique long run outcome involves a profit-maximising monopolist.
