General Equilibrium And Imperfect Competition: Profit Feedback Effects And Price Normalisations

Author

Abstract

There are two general issues which bedevil general equilibrium models with imperfect competition: price normalisation and the feedback from prices to incomes. We present a class of normalisations which do not affect the behaviour of oligopolists, this is argued to be the only class of normalisations with this general property. We also provide a set of necessary conditions for the existence of equilibrium with monopoly and feedback effects.
