Looking at the Cost Side of "Monopoly."
Welfare loss under oligopoly is defined as that part of consumer surplus which is lost and not regained by higher profits. In a model with asymmetric firms, this implies that the total welfare loss consists of the deadweight loss triangle plus a cost side inefficiency effect, due to the fact that in imperfect markets not all firms utilize the lowest cost technique. Using a flexible CV-model, the authors calculate these effects empirically for two relatively homogeneous industries (pulp/paper and cement). The deadweight loss triangles are shown to be smaller than the cost difference effect ('the staircase') for these industries. Copyright 1997 by Blackwell Publishing Ltd
