A MARKET WITH A SOCIAL CONSUMPTION EXTERNALITY*

We model a spatial market in which the utility of each consumer is affected by the consumers who buy precisely the same product. The marginal contribution of consumers x's purchase on consumer y depends on |x–y|, which declines as |x–y| increases. Such modelling of preferences fits goods that signal a consumer's place in society—clothing styles, automobiles and jewellry are examples. For 2n + 1 firms we find the unique symmetric equilibrium and derive comparative statics on the optimal number of firms, the largest number of firms the market can support, and the behaviour of profits per firm as n increases.     

A rejoinder

Abstract

This paper reflects on the influence of Vilfredo Pareto's letters on Ricardian equivalence and fiscal theory to Benvenuto Griziotti and Guido Sensini. The letters are important for emphasizing the need for fiscal studies to consider equilibrium, particularly social equilibrium, at a time when Italian fiscal sociology was in its formative stage. Griziotti came to accept fiscal sociology, albeit in an eclectic form that focused directly on political and legislative matters rather than social equilibrium. In contrast, Sensini progressively developed a framework for fiscal theory that focused primarily on the fundamental relationship between fiscal phenomena and social equilibrium.
