Clarke's subdifferential calculus
Perhaps the words "locally Lipschitz" should link to Lipschitz continuity? (Collin237) —Preceding unsigned comment added by 166.217.154.85 (talk) 05:15, 7 February 2011 (UTC)


 * Thanks for the suggestion, which prompted this revision: "Clarke's differential calculus for  Lipschitz continuous functions, which uses Rademacher's theorem".
 * Please continue to suggest improvements, here and elsewhere.
 * Best regards, Kiefer.Wolfowitz  (Discussion) 19:09, 18 February 2011 (UTC)

Add a reference to Koopmans
Tjalling Koopmans was the first to proof the non-existence of Walras-equilibria when production sets are non-convex. A reference to the "Three Essays on the State of Economic Science" is in place. One should include a graphics of his simple but enlightening example. This may help to understand the problem of non-convex production for non-scientists.--Hjsalchow (talk) 20:09, 10 May 2011 (UTC)
 * I incorporated and lightly edited a section from the Shapley-Folkman lemma, which carefully documents Koopmans's importance. Please add more about Koopmans, perhaps using the information in the footnote about his essay on convexity.
 * (I would rephrase your statement as his having given an example without a Walrasian equilibrium.) Best regards, Kiefer .Wolfowitz 20:12, 10 May 2011 (UTC)
