Italian Abstract: Vengono esposti i classici risultati dei modelli di oligopolio con beni differenziati sia sostituti che complementari a mosse simultanee, sequenziali e colllusive, con variabile strategica quantità o prezzo. L'utilizzo di funzioni lineari permette di calcolare, disegnare e...

We introduce a model of oligopoly dynamic pricing where firms with limited capacity face a sales deadline. We establish conditions under which the equilibrium is unique and converges to a system of differential equations. Using unique and comprehensive pricing and bookings data for competing...

We present a formal model of symmetric n-firm Cournot oligopoly with a heterogeneous population of optimizers and imitators. Imitators mimic the output decision of the most successful firms of the previous round a la Vega-Redondo (1997). Optimizers play a myopic best response to the opponents'...

This article explains the economics and antitrust of bundling. I first show that popular arguments such as demand complementarities, economies of scope, and price discrimination are not sufficient. I then detail potentially anticompetitive factors such as leverage and opacity. I then use simple...

This paper models a generalized form of monopolistic competition such that consumers are differentiated horizontally by taste while firms are differentiated vertically by quality location. Consumers have quadratic transportation costs of disutility from consuming a non-ideal brand, and firms are...

In this paper we consider how the degree of risk aversion, and demand/cost uncertainty, influence competition on oligopolistic markets. Under demand uncertainty, the best response strategies (both quantities and prices) are decreasing in risk aversion, but for cost uncertainty, quantities are...

We develop a model of Cournot competition between capacity-constrained firms that sell a single good to multiple regions. We provide a novel characterization for the unique equilibrium allocation of the good across regions and design an algorithm to compute it. We show that a reduction in...

The debate on the regulation of minority shareholdings as a type of “structural link” between competing undertakings is not a new one in the sphere of EU competition law. As a matter of policy, the incomplete and rather divisive treatment of minority shareholdings under the current EU merger...

Two related models of oligopolistic price competition with homogeneous products are presented. These models are based on weaker assumptions about consumer behavior compared to a classical Bertrand model. In both models firms do not necessarily face a discontinuous demand at an equilibrium price...

This paper investigates the market equilibrium and welfare effects of two-part tariff competition. When consumers are uniformly distributed on a Hotelling line, equilibrium prices are equal to marginal costs if and only if the demand of the marginal consumer is equal to the average demand. Entry...
