A simultaneous-equations framework is used to study the relationship between structure, conduct, and performance in US manufacturing in the 1980s and 1990s. The paper expands on earlier structure-conduct-performance studies by using a lag structure to signify that structure, conduct and performance do not affect one another contemporaneously. Findings support some aspects of the traditional structure-conduct-performance model, but challenge others. First, the data suggest that industry structure does not depend on current industry performance. Second, little evidence is found that industry conduct, proxied by advertising, is affected by industry structure. Third, results show that industry performance does not depend on industry conduct, though it is sensitive to industry structure. Thus, the main findings are that (1) concentration does not depend on firm profitability, though profitability depends on concentration, (2) advertising follows a process that is independent of the factors considered here, and (3) advertising seems to have no effect on profitability.
