Eléments pour une macroéconomie de la concurrence imparfaite


  • Louis-André Gérard-Varet


[eng] Elements of macroeconomics of imperfect competition. . In this paper we provide a general framework - the so-called "cournotian monopolistic competition" model - to highlight how imperfect competition on the good markets, with increasing returns and variability of the mark-ups, allows for endogenous fluctuations in the economy. The analysis is conducted in the broader perspective to design macroeconomics of contemporary economies as macroeconomics of imperfect competition. [fre] On présente, dans cet article, un cadre général - celui de « la concurrence monopolistique cournotienne » - permettant de mettre en valeur la manière dont la concurrence sur le marché des biens peut, en présence de rendements croissants et d'une variabilité des facteurs de marge, être à l'origine de fluctuations endogènes de l'activité. L'analyse est conduite dans la perspective plus large de la conception d'une macroéconomie des économies contemporaines comme macroéconomie de la concurrence imparfaite.
