THE NATURE AND LIMITS OF NATIONAL-INCOME CALCULATIONS

This article deals with questions with which I have been concerned for over sixty years but which I would not have been able to write withou t the invaluable help of my life-long friend Dr. Tom Soper. He not onl y edited various drafts of the article itself but contributed many ori ginal ideas and insights and generally influenced its contents. I also wish to thank my secretary Mrs Jackie Finlay, without whose help and constant encouragement the article would not have been written at all. I also wish to thank Miss Joan Kennedy and her staff for their great personal helpfulness to me.
