We examine the price decisions in a vertically differentiated duopoly where the decision to buy a good depends not only upon the intrinsic utility from consuming it but also upon the social attributes (prestige, uniqueness etc) associated with its consumption. These social attributes are...

There are examples of entry in two-sided markets, where first entrants occupy a `central location' and serve agents with `intermediate tastes', while later entrants are niche players. Why would the first entrant choose to become a `general' platform, given that later entrants will not have...

We show that the entry of a second firm in a horizontally differentiated market (ala Hotelling) may harm consumers as prices increase and consumer's surplus possibly decrease. We first derive the price and the consumer's surplus of a monopoly which is located at the center of the market. When a...

We model pre-investment R&D decisions in the presence of spillover effects in an option pricing framework with analytic tractability. Two firms face two decisions that are solved for interdependently in a two-stage game. The first-stage decision is: what is the optimal level of coordination...

We show that the entry of a second firm in a horizontally differentiated market (ala Hotelling) may harm consumers as prices increase and consumer's surplus possibly decrease. We first derive the price and the consumer's surplus of a monopoly which is located at the center of the market. When a...

In this paper we characterize the existence of best choices of arbitrary binary relations over non finite sets of alternatives, according to the Generalized Optimal-Choice Axiom condition introduced by Schwartz. We focus not just in the best choices of a single set X, but rather in the best...

We show that the entry of a second firm in a horizontally differentiated market (ala Hotelling) may harm consumers as prices increase and consumer's surplus possibly decrease. We first derive the price and the consumer's surplus of a monopoly which is located at the center of the market. When a...

We demonstrate to decision makers how to optimally make costly strategic pre-investment R&D decisions in the presence of spillover effects in an option pricing framework with analytic tractability. Decisions are modeled as impulse-type controls with random outcome. Two firms face two decisions...
