"August 1956.""The attached memorandum is submitted for your information and to invite your friendly but nevertheless penetrating criticism. The present version which is as accurate as I could make it attempts to document every figure used and to justify every step undertaken. In the final version many of the intermediate calculations will be omitted. I should be especially grateful if you would draw my attention to any logical slips I might have made or to any material I have overlooked. Because this is only a preliminary version I should appreciate it if you do not quote it."--Cover"Communist Bloc Program, East Germany Project."Includes bibliographical references
