Résumé en anglais

Interest in economies with a finite number of equilibria has been first drawn over by Debreu (1970). The present paper shows that such economies form a subset of dense interior of the set of private ownership economies and proves some continuity properties of the Walras correspondence. It generalizes similar results obtained for exchange economies by Dierker and Dierker (1972). Demonstrations also rest heavily on transversality theory but use somewhat stronger theorems.
