Sources of Structural Change in the United States, 1963-78: An Input-Output Perspective.

A 400-sector input-output framework is used in the decomposition of industry output change in the United States during the period 1963-78 into the portion att ributable to changes in the level and composition of final demands, and the fraction attributable to changing input-output coefficients. The analysis concludes that, for nearly 80 percent of the 400 industri es, final demand changes account for the majority of output change. The most rapidly growing and most rapidly declining sectors are among those most affected by coefficient change. These results underscore the role of aggregate economic policy as a channel of any national industrial policy. Copyright 1987 by MIT Press.
