| Abstract: | This paper presents a simultaneous equations model of profitability, concentration, advertising, and research and development outlays. We find that research and development intensity tends to increase in more concentrated industries, although this effect is negated in industries where technological opportunities are excellent. Also, high levels of research and development may reduce concentration while tending to add to industry profitability. These results suggest that the government should not be concerned with the possibility of an adverse impact of market concentration on research and development, although the evidence suggests that certain high technology industries may be at a small risk. |
