This Paper studies the inter-temporal problem of a monopolistic firm that engages in productivity-enhancing innovations to reduce its labour costs. If the level of wages is sufficiently low, the firm's rate of productivity growth approaches the rate of wage growth and eventually the firm reaches...

We describe the evolution of productivity growth in a competitive industry. The exogenous wage rate determines the firms' engagement in labor productivity enhancing process innovation. There is a unique steady state of the industry dynamics, which is globally stable. In the steady state, the...

Our model studies the evolution of productivity growth in a competitive industry. The exogenous wage rate determines the firms' engagement in labour productivity enhancing process innovation. There is a unique steady state of the industry dynamics, which is globally stable. In the steady state,...

This paper studies the innovation dynamics of an oligopolistic industry. 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...
