This paper studies the innovation dynamics of an oligopolistic in-
dustry. The firms compete not only in the output market but also by
engaging in productivity enhancing innovations to reduce labor costs.
Rent sharing may generate productivity dependent wage differentials.
Productivity growth creates intertemporal spill–over effects, which af-
fect the incentives for innovation at subsequent dates. Over time the
industry equilibrium approaches a steady state. The paper character-
izes the evolution of the industry’s innovation behavior and its market
structure on the adjustment path.
