Prices should reflect the relative costs and benefits of economic activity. Responding to prices, different economic actors (consumers, workers, managers, entrepreneurs, and so on) can be led to efficient outcomes. We have already seen that markets can fail when prices fail to incorporate spillovers. Prices can also be distorted when buyers and sellers exert significant market power, for instance, a monopolist can choose to restrict supply and drive prices and profits upwards. While this can be bad for overall efficiency, it can, of course, be good for those lucky enough to possess such market power. Today we begin by studying the exploitation of monopoly power. We also bring in the effects of increased competition and work out the relationship between competition and economic performance. The third lecture explores coordinated effects: when firms misuse their combined market power to raise prices. Needless to say excessive market power can be bad for firms as well as a concern for governments; after all, if your supplier is a monopolist then you may be held to ransom. We conclude the day with a lecture that highlights some issues in modern antitrust and competition law.
