----------------- HES POSTING ----------------- I have seen a draft, written on April 1962, of a paper by Samuelson on "Distinction of the Hicks and Harrod definitions of neutral technical change", but I haven't been able to find out whether and when it was published. Could anyone help? Thank you very much. Daniele Besomi ------------ FOOTER TO HES POSTING ------------ For information, send the message "info HES" to [log in to unmask]
