Three Equivalent Salop Models and their Normative Representative Consumer

Steffen Hoernig ()

FEUNL Working Paper Series from Universidade Nova de Lisboa, Faculdade de Economia

Abstract: We show that three location models on the Salop circle, involving linear or quadratic transport cost, and asymmetric locations or fixed benefits, are equivalent: they lead to the same demand functions and consumer surplus. The only exception is the case of asymmetric lo- cations with an even number of firms, which has one less degree of freedom. These models are also fully equivalent to a normative rep- resentative consumer whose indirect utility is given by the standard Salop consumer surplus. This result provides a further unification of location and representative consumer models. JEL codes: D11, D43
