The New Industrial Organization and Small Business

The small business sector is an important part of the American economic landscape, in both absolute and relative terms. Despite its absolute growth, however, the sector accounts for a diminishing share of private sector activity. But its importance, and changes in importance, vary across industrial sectors of the economy. Drawing on the theoretical and empirical insights developed in recent books by John Sutton, we suggest that the presence or absence of endogenous strategic behaviors of the larger firms with respect to advertising, promotion, research and development, and other sunk cost expenditures may well play an important role in explaining the differing levels of small business importance, both cross-sectionally and over time. We conclude the paper with suggestions for research directions that could shed further light on these ideas

The Effect of Market Growth and Contraction on Industry Price-Cost Margins

Economic theory predicts that market growth or contraction may affect the role of industry concentration upon price-cost margins. Existing empirical work, however, has not specified the relationship completely or correctly. This article sets out a model consistent with theory and then tests several hypotheses on manufacturing industry data. It finds that the effect of concentration on industry pricing behavior declines when the overall market either grows or contracts sharply, and declines when the industry is highly capital-intensive. The effect of concentration, however, persists for the vast majority of cases.

Firm-size distribution and price-cost margins in Dutch manufacturing

Industrial economists surmise a relation between the size distribution of firms and performance. Usually, attention is focused on the high end of the size distribution. The widely used 4-firm seller concentration, C4, ignores what happens at the low end of the size distribution. An investigation is presented of the extent to which the level and the growth of small business presence influence price-cost margins in Dutch manufacturing. A large data set of 66 industries for a 13-year period is used. This allows the investigation of both small business influences within a framework in which that of many other market structure variables is also studied. Evidence is shown that price-cost margins are influenced by large firm dominance, growth in small business presence, capital intensity, business cycle, international trade, and buyer concentration
