Economic reform, structural adjustment, macroeconomic stabilization, and participation in the world economy are interconnected aspects of the same issue: the long-term economic viability of centrally planned economies in the rapidly changing economic environment of the modern world. Any economic strategy that focuses on only one or two of these aspects at the expense of the others is likely to fail; yet even strategies that build on all of these bases may well fail unless political leaders can muster exceptional skill, garner international support, and enjoy some good luck.The contributions to this volume reflect the recent research on this issue by various specialists on the economies of the Soviet Union and Eastern Europe. Each author emphasizes macroeconomic stabilization, structural adjustment, participation in the larger world economy, or ecomonic reform.
