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. 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.

We test the hypothesis that variations in industry price-cost margins (PCM) performance are explained by sellers' various structure and conduct variables such as sellers' concentration (i.e., HHI for value added), capital-output ratio, barrier to entry, industry demand growth rate, import penetration export share, and degree of foreign participation (multinational) in four-digit Philippines Standard Industrial Classification manufacturing industries. The statistical analyses are a series of multiple regression equations relating the PCM to the previously-mentioned explanatory variables. Estimation results show a generally positive relationship between sellers' concentration, capital intensity, degree of foreign participation and the PCM. Industry growth rate may either increase or reduce PCM. Imports and exports lower PCM.
