Abstract: Market structure's influence on price-cost margins was explored in each census year over a 23-year period in food manufacturing. The positive relationship between price-cost margins and both four-firm concentration and product differentiation, as measured by a media advertising-to-sales ratio, became stronger over time. The reverse was true for the relationship between plant economies of scale and price-cost margins. The results indicate that in food manufacturing the influence of market concentration on profits does not disappear during inflationary periods as is often the case in studies of general manufacturing industries.
