Description du contenu de l'enseignement
We study the strategies of firms which can be classified according to the speed at which they are likely to be modified. In the short term, prices and quantities are the variables that firms can easily modify. We will deepen the study of this short-term competition initiated in the first semester, focusing, in particular, on the consequences of a stronger concentration of firms on a market and on the factors defining the degree of competition between firms. We will also study medium-term strategies, in particular the investment strategy of a firm to erect barriers to entry into its market or the choice of the characteristics of its product.
A la fin de ce cours, vous serez capable de :
- de formaliser les stratégies des firmes et leurs interactions par un jeu non coopératif simultané ou séquentiel,
- d'appliquer les outils de la théorie des jeux (concepts d'équilibre de Nash et d'équilibre parfait en sous-jeux) pour déterminer les stratégies des firmes et leurs profits,
- d'évaluer les impacts des stratégies des firmes sur leurs profits, la performance de l'industrie et le bien-être social.
- to formalize the strategies of firms and their interactions through a simultaneous or sequential non-cooperative game,
- to apply the tools of game theory (Nash equilibrium and subgame-perfect Nash equilibrium) to determine the strategies of firms and their profits,
- to assess the impact of firms' strategies on their profits, industry performance and social welfare.
Compétences à acquérir
The purpose of this UE is to pursue the analysis of market structures initiated in the Industrial Economics course 1. For this analysis we will first discover the tools of game theory that have been developed to facilitate the understanding of interactions between rational decision-makers. The imperfect competition between firms on the markets is typically a situation of interaction of rational agents. For this reason, we will then use these game theory tools to study firm strategies and their consequences for industrial organization and social welfare. The ultimate objective is to shed light on the rational foundations of public policies.
