In this paper, we show that, in markets with a continuum of traders and atoms, the set of Coumot-Walras equilibria does not coincide with the set of Coumot equilibria. We show also that, when the preferences of the traders are represented by Cobb-Douglas utility functions, the set of...

We consider the model of exchange " A la Coumot”, originally proposed by Lloyd S. Shapley and analysed by S. Sahi and S. Y80 (1989), in markets with a continuum of traders. We show that each active Coumot equilibrium is a Wahas equilibrium and each Wahas equilibrium is a Coumot equilibrium
