This studies the strategic decisions taken by firms in markets, in particular when they have market power.
First, we will try to understand what market power is and how firms behave in markets. To do so, the course will introduce the classical models of imperfect competition in markets.
In the second part, we will investigate cartels, tacit collusion, and its consequences on welfare and antitrust policies. One important aspect of antitrust policy is mergers. Mergers between direct competitors are known as horizontal mergers. We try to understand if and when such mergers are profitable and welfare-enhancing.
In the third part, we will investigate how a firm can be a natural monopolist, without fearing entry, and how incumbent firms may behave strategically to make entry for new firms harder, or even unprofitable.
In the fourth part of the course, we analyse firms with vertical supply chains. Could upstream firms deny competitors access to distribution and supply channels?
Lastly, we study applications of behavioral economics on industrial organization and regulatory issues. Here, we discuss potential regulations to protect customers if customers suffer from behavioral biases.
