Course video 44 of 90

Our fifth lecture focuses on games where firms are in different stages of the competition game. In this setting there exists a monopolistic firm already in the market, while another firm considers entering this market in the future. We will examine how the incumbent firm will be affected by the prospect of entrance. We will cover all basic principles of deterrence for the protection of the incumbent’s territory. We will talk about, credibility, empty threats, preemption, contestability and strategic relevance. We will examine the four general business strategies for deterrence and we will see a very intriguing paradox that can teach us a lot about credibility and the importance of reputation.
