This thesis examines the origins and evolution of Western export controls intended to limit the transfer of high technology, particularly computers, to communist countries, and how technology policy within the Soviet Union and other communist states was shaped by these controls. This work intends to demonstrate that Western attempts to control trade in high technology were responsive to changing economic and political realities and that changes in export controls produced corresponding changes in policy within the USSR. Ultimately, policies on both sides served to maintain and widen the technology gap between East and West far more dramatically than anticipated, deepening the economic stagnation of Eastern Europe and hastening the collapse of communism.
