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.","lang":"eng"}],"doi":"10.1016/0304-4068(80)90011-7","publication":"Journal of Mathematical Economics","urn":"urn:nbn:de:0070-pub-17814036","file_date_updated":"1970-01-01T00:00:00Z","oa":1,"title":"Smoothing demand by aggregation with respect to wealth","volume":"7","intvolume":" 7","issue":"3","date_updated":"2018-07-24T12:59:16Z","citation":{"apa_indent":"Dierker, E., Dierker, H., & Trockel, W.
