James, T. and McHardy, J. (2009) An Elasticity Measure Of Welfare Loss In Symmetric Oligopoly. Working Paper. Department of Economics, University of Sheffield ISSN 1749-8368
Abstract
We derive a measure of welfare loss as a proportion of the value of sales under quantity-setting symmetric oligopoly in terms of the equilibrium industry price elasticity of demand, the number of firms in the industry and a conjectural variation term in the context of the standard linear model. This generalises the monopoly measure in James and McHardy (1997).
