Este documento analiza el comportamiento de la industria del cemento en Colombia en las últimas décadas. En particular, estudia la relación que existe entre el precio y las cantidades producidas de cemento durante el período 1980 - 2006, así como los determinantes del comportamiento de...

El objetivo del trabajo es presentar un panorama sobre el análisis de la demanda en mercados con producto diferenciado con especial atención a la metodología basada en los modelos de elección discreta. Se revisan los planteamientos teóricos y se centra la discusión en su aplicación...

We study cartel stability in a differentiated price-setting duopoly with returns to scale. We show that a cartel may be equally stable in the presence of lower differentiation, provided that the decreasing returns parameter is high. In addition we demonstrate that for a given factor of discount,...

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

The digitization of media and the growth of broadband internet has transformed the streaming video industry, and the subscription video on demand (SVOD) industry in particular. Online content providers (CPs) are trying out new business models that upend the traditional television industry that...

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...
