Objectifs

Part I:

The goal of the first part of the course is to make students familiar with nonstrategic market behavior and the exercise of monopoly power.

Part II:

The purpose of the second part of the course is to make students familiar with the basic models of strategic interaction in imperfectly competitive markets.

Contenus

Part I

The first part of the course will cover Part I of Jean Tirole’s book (chapters 1 to 4). We will follow the sequence of the book: monopoly behaviour, product selection, price discrimination and vertical control. At the end of the course regulation of monopolies will be discussed based on Laffont & Tirole (1993). More details on readings will be announced in class. We will also discuss some empirical papers which will be made available online.


1. Monopoly

Main questions: How should a monopolist set its price? What is the intertemporal pricing behavior of a durable-good monopolist? When should a durable-good monopolist rent rather than sell its product?

Readings:

-Tirole, Ch. 1

1.1 Pricing Behavior

1.2 Durable Goods and Intertemporal Price Discrimination

1.2.1 Leasing versus Selling

1.2.2 The Coase Conjecture

2. Product Selection, Quality and Optimal Number of Products

Main questions: What commodities should be produced and sold? Does a monopolist have an incentive to choose the optimal products from the perspective of a social planner?

Readings:

-Tirole, Ch. 2

2.1 The Notion of Product Space

2.2 Product Selection

2.2.1 Product Quality

2.2.2 Optimal Number of Products

3. Price Discrimination

Main questions: What is price discrimination? What are the types of price discrimination? What are the consequences of price discrimination?

Readings:

-Tirole, Ch. 3

3.1 Perfect (First-Degree) Price Discrimination

3.2 Multimarket (Third-Degree) Price Discrimination

3.3 Personal Arbitrage and Screening (Second-Degree Price Discrimination)

4. Vertical Control

Main questions: What are the factors that create an incentive for a producer of a final good to acquire vertical control of a supplier of an input when the market for the input is noncompetitive? What are the factors that create an incentive for a manufacturer to acquire vertical control of a retailer who can provide services to make the final good more attractive to consumers?

Readings:

-Tirole, Ch. 4

4.1 Externalities and Vertical Control

4.2 Double Marginalization

4.3 Downstream Moral Hazard


The second part of the course will cover Part II of Jean Tirole’s book (chapters 5 to 8). We will follow the sequence of the book: short-run oligopoly models, dynamic price competition and tacit collusion, product differentiation, and strategy and market structure. Before the start of the second part of the course you should refresh your knowledge of Game Theory. The best way to do that is to read chapter 11 (“Noncooperative Game Theory: A User’s Manual”) in The Theory of Industrial Organization.
