Comparative Productivity: The USSR, Eastern Europe, and the West
比较了1975年四个社会主义国家和七个西方市场经济国家的人均产出，发现西方国家的效率优势无法完全由资本和土地差异解释，存在25%至34%的残余差距。
This paper compiles comparative measures of output per worker in 1975 in four socialist and seven Western market economy (WME) countries, and explores sources of observed differences between the two groups of countries in that regard. Such differences seem explicable only partially by reference to differences in per worker capital stock and farm land. A residual disparity of 25 to 34 percent in favor of WME countries appears to testify to superior efficiency in the latter. Copyright 1987 by American Economic Association.
