The evolution of market structure in semiconductors: the role of product standards

This paper looks at the role of product standards in determining the evolut ion of market structure in semiconductors. Theory suggests that product sta ndards, along with learning-by-doing effects, lead to market concentration and persistence of leadership in product innovation, Empirical evidence sup ports this with some qualifications. The market concentration hypothesis is confirmed for all submarkets of the semiconductor industry. Persistence of leadership is obtained for markets based on proprietary product standards. In the market for microprocessors, we have persistence of leadership in pr oduct innovation that is accompanied with overall market dominance. For mic rocontrollers, we observe persistence of leadership in product innovation, but not concomitant overall market dominance. Whereas learning-by-doing eff ects seem to be strong in the small market for microprocessors, they are we aker in the much larger market for microcontrollers. (C) 2000 Elsevier Scie nce B.V.
