The fifth volume of the [Institute] series "Comparative Studies in Economics and Economic Systems" treats the problems of monetary relations between East and West.   The author, Dr. Adam Zwass brings his extensive knowledge of monetary relations in Eastern Europe, gained while he held a number of posts in Poland and during his association with the CMEA Secretariat in Moscow.  It was not the author's intention to draw up a m aster plan for closer cooperation between the two monetary systems, which differ widely in many respects. His main concern is the Eastern monetary system, and its instruments, institutions, and functions are subjected to a thorough analysis. Problems are pinpointed and suggestions made for improvements. Finally, Dr. Zwass considers the prospects for the development of a worldwide currency system. It is hoped that his book will stimulate further research that would pave the way for productive cooperation between East and West in monetary relations.This title was first published in 1975.
