While it is widely recognized that imports can discipline markets, the strength of that disciplinary power surely varies across industries. The determinants and extent of this interindustry variation in the disciplinary force for foreign trade flows is, however, relatively unexplored. This article investigates the microeconomic determinants of changing import shares at the industry level for U.S. manufacturing industries. Based upon this investigation, the authors are able to create an index that measures the relative vulnerability of the various manufacturing industries to foreign competition and test a number of hypotheses concerning the underlying causes of observed variations in import vulnerability.
