----------------- HES POSTING ----------------- I am writing a paper about the reasons why Patinkin decided that the Pigou effect had to be introduced in the Keynesian theory. The Don Patinkin Papers in Duke's archives show that he changed his mind on this matter between the submission of his Ph.D. thesis in 1947 and the publication of _Price Flexibility and Full Employment_ in 1948. They also show that this change of mind was prompted by a discussion he had with Milton Friedman and Alexander Morrel Henderson, the latter having exchanged a couple of letters with Patinkin between 1947 and 1948. Everybody knows Friedman, but A. M. Henderson would require a short biographical note. Alas! I have very few elements concerning his curriculum. I only know that he came from Cambridge University (U.K.), that he spent some time at the Rockefeller Foundations in New York in 1947 and then at Harvard University in 1948, and that he probably met Patinkin at the Cowles Commission in Chicago. Does someone know who he was, what he wrote and when he was born? Yours faithfully, Goulven Rubin University of Evry-Val-d'Essonne, France. ------------ FOOTER TO HES POSTING ------------ For information, send the message "info HES" to [log in to unmask]
