Italian Abstract: Dopo aver definito la differenziazione verticale come una caratterizzazione oggettiva della qualità che da luogo ad una indiscutibile utilità o produttività marginale crescente nella qualità, utilizzando il modello classico di Shaked e Sutton vengono determinati prezzi e...

Italian Abstract: Vengono esposti i tradizionali modelli di oligopolio con bene omogeneo a mosse simultanee, sequenziali e colllusive, con variabile strategica quantità o prezzo. L'utilizzo di funzioni lineari permette di calcolare e comparare tutte le soluzioni

This paper revisits a particular behaviour for firms competing in imperfect competitive markets, underlying the well known model of kinked demand curve. We show that under some symmetry and regularity conditions, this asymmetric behaviour of firms sustains monopoly pricing, and possesses...

Italian Abstract: Note sui modelli classici di strategie di differenziazione orizzontale del prodotto con costi di trasporto lineari Hotelling (1929) e quadratici D'Aspremont, Gabsewicz e Thisse (1979). Vengono studiati i risultati dovuti ad imprese con funzioni di costo diverse. Segue una...

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...

The issue I want to take up here is how networks influence firm business not only from the costs and R&D side, but also from the demand side because of substitution - complementarity effects. In other words firms face networks at every intermediate level that has to meet the market. I will...

This article presents a new approach to analyze the equilibrium set of symmetric, differentiable games by separating multiple symmetric equilibria and asymmetric equilibria. This separation allows the investigation of, for example, how various parameter constellations affect the scope for...

In this paper we analyze R&D collaboration networks in industries where firms are competitors in the product market. Firms' benefits from collaborations arise by sharing knowledge about a cost-reducing technology. By forming collaborations, however, firms also change their own competitive...
