Introduction d'un processus d'apprentissage dans un modele avec concurrence cournotienne

This paper examines underemployment fluctuations in an OG model with cournotian competition on the market for a good. In the case of constant returns, it demonstrates the existence conditions of a stable two-period cycle (in prices and employment amounts) in the backward perfect foresight dynamics. It studies its becoming in the forward dynamics thanks to a learning process. These results are essentially based on the variablity of firm's market power as a consequence of the variability of demand elasticity.
