Conflict between consumer and worker surpluses under monopoly power

Economics Letters, 2024, vol. 234, issue C

Abstract: Using a simple model of monopoly and monopsony, I examine the effect of a labor-augmenting productivity gain on workers. I show that, although such a productivity gain always increases the output and consumer welfare, a firm with monopoly power may lower the labor demand and worker welfare because of the discrepancy between the marginal product and marginal revenue product of workers. The misalignment between consumer and worker welfare suggests that competition authorities need to be cautious about the potential harm of consumer-benefiting productivity gains on workers when assessing antitrust cases such as mergers.
