Search costs decrease prices in a model of spatial competition

Abstract

type="main" xml:lang="es"> Este artículo examina los precios de equilibrio de Nash de tiendas comerciales dentro de un modelo de búsqueda espacial. Se parte del supuesto de que las grandes tiendas almacenan con toda certeza el producto en particular que quiere un consumidor, mientras que la pequeña tienda cuenta con una probabilidad w. Las tiendas grandes y pequeñas se alternan en una carretera circular. Los consumidores deben visitar las tiendas para buscar. En el precio de equilibrio de Nash, las tiendas grandes cobran precios más altos que las tiendas pequeñas. Quizás, sorprendentemente, todos los precios de equilibrio de Nash son menores que en el modelo de información-perfecta-no-búsqueda correspondiente (para un valor dado de w). Este último resultado queda demostrado también en un modelo que sólo cuenta con tiendas pequeñas.
