Including Imperfect Competition in Spatial Equilibrium Models Academic Article uri icon

abstract

  • Following Martin's paper on quadratic spatial equilibrium models this paper presents ways to incorporate imperfect competition in these models by altering the objective function of the quadratic program. This paper shows how the standard Cournot and Slackelberg equilibria may be modelled. The paper also describes the new theoretical models of consistent conjectural variations and how they may be translated into quadratic spatial equilibrium models. Situations that are likely to be modelled are discussed and appropriate models are presented. More complicated equilibria that cannot be modelled by simple adjustment of the quadratic objective function are also discussed. Aprs la composition de Martin sur les modeles de L'quilibre quadratique et spatial, nous presentons des moyens d'incorprer la comptition imparfaite dans ces modeles en modifiant la fonction objective du programe quadratique. Nous montrons comment on peut modeler les quilibres Cournot et Stackelberg. Nous dcrivons aussi les nouveaux modeles thoriques des variations consistentes et conjecturales, et comment ils peuvent ytre traduits en modeles de l'quilibre quadratique et spatial. Nous discutons les situations qui peuvent probablement tre modeles et nous presentons des modeles qui nous semblent appropris. Nous discutons aussi des quilibres plus compliqus qui ne peuvent pas tre models par un simple ajustement de la fonction objective et quadratique. Copyright 1984, Wiley Blackwell. All rights reserved
