Does Standardization Really Increase Production?Journal articleHubert Stahn, Annals of Economics and Statistics, Issue 49-50, pp. 381-388, 1998

In market structures with network externalities, it is often asserted that there is a natural tendency toward standardization. In this paper it is argued that incompatible products may survive in static models. Like Katz and Shapiro [1985], I develop a simple multi-product oligopoly in which the demand for one of these commodities increases with the number of agents consuming this good. Instead I introduce a variety of cost functions and discuss the limitations of their results of Katz and Shapiro and exhibit an example that reverses their conclusions.

Un modèle de concurrence monopolistique: une approche en équilibre généralJournal articleHubert Stahn, Annals of Economics and Statistics, Issue 43, pp. 29-56, 1996

This paper is devoted to the study of the existence of a general equilibrium with price making firms. I assume that each firm is able to compute an objective demand for his produced goods and uses this information in order to set prices. The definition of an objective demand is set in a context of general equilibrium and the existence of such a continuous function is proved under few assumptions. I also define a monopolistic equilibrium conditional to this objective demand and show it existence under standart assumptions.
