Firm Learning and Market Equilibrium. Ariel Pakes, 2018, Paper, "One goal of the field of industrial organization is to predict the response of markets to environmental or policy changes. A market, for our purposes, is a collection of firms that produce and sell competing products or services. Since the consequence of, say, a price change by a given firm depends on the prices of competing firms, realism requires analyzing these changes in the interacting agent frameworks supplied to us by our game theory colleagues. If a firm had set a profit maximizing price before an environmental change, that price was unlikely to be optimal after, say, a tariff or merger induced a price change by a competitor. It is important to take account of the price adjustments that followed the initial price change." Link
