Instead of imposing a manifold structure on preferences we exploit the nice structure of wealth-space. The first step of this procedure, aggregation with respect to wealth, is carried out. It is shown that, for any preference, aggregation with respect to wealth yields a mean demand which is almost everywhere C 1. Moreover, it is shown that for an important class of preferences, vanishing Gaussian curvature of indifference surfaces does not destroy differentiability of the mean demand function."]},"accept":"1","publication_status":"published","first_author":"Dierker, Egbert","language":[{}],"department":[{"tree":[{"_id":"10053"}],"_id":"10053"}],"publication_identifier":{"issn":[]},"uri_base":"https://pub.uni-bielefeld.de","isi":"1","date_submitted":"2011-01-10T10:12:39Z","issue":"3","author":[{"last_name":"Dierker","autoren_ansetzung":["Dierker, Egbert","Dierker","Egbert Dierker","Dierker, E","Dierker, E.","E Dierker","E.
