Obiettivi Formativi
OBIETTIVI FORMATIVI: Lo scopo del corso è quello di introdurre gli studenti al ragionamento strategico mediante lo studio della teoria dei giochi ed applicare questo strumento all'analisi della competizione tra imprese. In particolare, svilupperemo gli ingredienti basilari della teoria dei giochi non cooperativi e le nozioni di equilibrio appropriate ai diversi contesti. Infine studieremo come applicare questi strumenti alla progettazione di politiche pubbliche a contrasto
CONOSCENZA E CAPACITÀ DI COMPRENSIONE:
Alla fine del corso gli studenti dovrebbero essere in grado di comprendere e applicare l'approccio logico della teoria dei giochi all’analisi del contesto strategico in cui le imprese operano. Studieremo le condotte anti-concorrenziali e le politiche pubbliche a contrasto.
CAPACITÀ DI APPLICARE CONOSCENZA E COMPRENSIONE:
Alla fine del corso gli studenti dovrebbero essere in grado di identificare autonomamente condotte potenzialmente anti-concorrenziali.
AUTONOMIA DI GIUDIZIO:
Alla fine del corso gli studenti dovrebbero essere in grado di comporre un quadro normativo e suggerire interventi e strumenti utili al contrasto.
ABILITÀ COMUNICATIVE:
Alla fine del corso gli studenti dovrebbero essere in grado di analizzare condotte di mercato e preparare delle presentazioni per discuterne gli effetti sulla concorrenza.
LEARNING OUTCOMES: the aim of this course is to introduce students to strategic reasoning through a formal training in game theory and a parallel set of lectures on applications to competition policy. Specifically, we will formally introduce the basic ingredients of non cooperative games and a number of equilibrium concepts used to solve them. These will be applied to studying strategic interaction among firms and to design incentive schemes to achieve a number of basic public policy goals.
KNOWLEDGE AND UNDERSTANDING:
At the end of the Course students should be able to understand and apply the logical approach of game theory to analyse the strategic environment that firms face in regime of oligopoly. In particular, we will study anti-competitive conducts put forth by firms and public policies to address them. Emphasis will be given to the role of algorithms and digital markets such as search engines, social media or online marketplaces.
APPLYING KNOWLEDGE AND UNDERSTANDING:
At the end of the Course students should be able to apply the knowledge to identify potential anti-competitive practices.
MAKING JUDGEMENTS:
Given a firm's conduct, the student should be able to (i) sketch its overall impact on economic surplus and its redistributive impact on the individual surplus of the parties involved and (ii) suggest potential interventions.
COMMUNICATION SKILLS:
At the end of the course students should be able to analyse market practices and prepare presentations to discuss their effects on competition.

Game Theory (first part of the course)
Programma
Questo corso mira a fornire una comprensione teorica e pratica delle principali
questioni
relative all'organizzazione industriale e alla politica di concorrenza. Utilizzando concetti di
base nella teoria dei giochi, il corso studia l'interazione strategica tra imprese in mercati
imperfettamente competitivi, le fonti del potere di mercato, la logica e l'impatto della politica
di concorrenza. Le lezioni frontali faranno uso di strumenti analitici, esempi pratici e casi di
studio.

Program
This course aims at providing a theoretical and practical understanding of main
issues in
industrial organization and competition policy. Using basic concepts in game theory, the
course studies the strategic interaction among firms in imperfectly competitive markets, the
sources of market power, and rationale and impact of competition policy. Lectures will
make use of analytical tools; practical examples will be provided throughout. A number of
case studies are discussed.
Topics covered:
What are 'Markets and Strategies'?
Firms, consumers and the market
Standard Bertrand Model
Cournot Competition
Strategic substitutes vs strategic complements
Stackelberg model
Sources of Market Power
Product differentiation
Horizontal product differentiation
A simple location model
The linear Hotelling model
The Quadratic Hotelling Model
Vertical product differentiation
Theory of Competition Policy
Cartels and tacit collusion
Sustainability of Tacit Collusion
Collusion and multimarket contact
Detecting and fighting collusion: leniency programs
Horizontal mergers
Profitability of simple Cournot Mergers
Mergers between several firms
Efficiency increasing mergers
Welfare Analysis of Cournot mergers
Strategic incumbents and entry
Strategies Affecting Demand variables
Brand Proliferation
Bundling

OLD:The course comprises lectures and seminars.
Regolamento Esame
Esame scritto composto da due sezioni. Nella prima sezione si farà riferimento alla teoria
con dimande a risposta aperta. Nella seconda sezione si testerà la capacità del candidato
di risolvere eseercizi e di illustrare i modelli teorici studiati in classe con il linguaggio della
matematica.
Exam Rules
The exam is written and it lasts 1.5 hours. It is potentially composed of different sections.
The first section is theoretical: the candidate is required to answer concisely questions on
the course material with short essays. The second will test the candidate's knowledge of
formal models of competition using the language of mathematics by either asking to present
and discuss them or asking to solve exercises.
