BUYERS' STRATEGIES, ENTRY BARRIERS, AND COMPETITION.

In markets where sellers have customer-specific investments, and buyers can make credible, but costly, commitments to switch suppliers, buyers' strategies attenuate the market power of sellers. Furthermore, since current prices and a buyer's decision to switch suppliers are related, limit pricing becomes an equilibrium.

Thus, sunk investments may restrain the sellers' ability to exert market power. The paper questions, then, the standard inverse relationship between market performance and sunk investments.
