Safe harbor input prices and market exclusion

Author

  • Dennis Weisman

Abstract

An essential input price that is “too high” relative to the downstream price leads to inefficient foreclosure and one that is “too low” induces the vertically-integrated firm to engage in non-price discrimination. Displacement ratios are used to derive the range of safe harbor (downstream/upstream) margin ratios within which no market exclusion arises in equilibrium. The range of admissible margin ratios is increasing in the degree of product differentiation and reduces to a single ratio in the limit as the products become homogeneous. A key policy finding is that complementary price-ceiling and price-floor constraints can prevent both forms of market exclusion. Copyright Springer Science+Business Media New York 2014
