The traditional theory of price index numbers is based on the law of one price. But in the real world, we frequently observe the existence of an equilibrium price dispersion instead of one price of equilibrium. This article ...

We investigate how the structure of price dispersion is in Argentina. We use daily data reported by supermarkets and we measure price dispersion at the bar code level in order to analyze whether supermarkets set prices ...

This paper extends the oligopolistic model of price competition to environments with multiple goods, heterogeneous consumers, and arbitrary continuous cost functions. A Nash equilibrium in mixed strategies with an endogenous ...

In this paper a model is presented based on ideas borrowed from the job search and price dispersion literature to characterise the pricing equilibrium of a competitive bus market in a more general setting than previously ...

This paper studies the relation between inflation and relative price variability (RPV) in Spain during the 1987-2009 period. We find that this relation presents a U-shape profile, and that the optimal annual inflation rate ...
