Abstract: We investigate the existence and Core stability properties of several types of competitive equilibria in markets for pure indivisibles where trades are organized between groups of agents. Equilibrium concepts are defined according to the type of cooperation prevailing within coalitions. We show that existence crucially depends on the definition of group budget sets, where individual incomes may or not be merged into group incomes.
