摘要：

We show that under decreasing returns to scale there are continua of non-zero profit mixed Bertrand equilibria where firms randomise between any finite number of pure equilibrium prices. Unlike the previous literature we do not assume infinite monopoly profits. (C) 2002 Elsevier Science B.V. All rights reserved.
