In this book Mark Harrison rebuilds and analyses the Soviet economy's wartime statistical record, examining its prewar size and composition, and wartime changes in GNP, employment, the defence burden, and the role of foreign aid. Complementing classic long-run growth studies, the book compares the Soviet experience with that of other great powers. It emphasises the severity of current costs and capital losses arising from the war, which had a negative effect on GNP that persisted well after the end of the war. The results are based on a comprehensive analysis of hitherto closed official documents, shedding light on the dimensions of the Soviet war effort, the comparative economics of the war, and its long-term impact on the Soviet economy.
