We set-up a linear city model with duopoly upstream and downstream. Consumers have a transportation cost when buying from a retailer, and retailers have a transportation cost when buying from a wholesaler. We characterize the equilibria in a five-stage game where location and pricing decisions...

We examine the implications of different contractual forms for welfare as well as for firms’ profits in a framework in which a vertically integrated firm sells its good to an independent downstream firm. Under downstream Bertrand competition, the standard result of the desirability of two-part...

We propose a two-sided model with two competing Internet platforms, and a continuum of Content Providers (CPs). We study the effect of a net neutrality regulation on capacity investments in the market for Internet access, and on innovation in the market for content.Under the alternative...

We analyse the exchange-rate exposure (exposure) and systematic risk (beta) of individual stocks and pair arbitrage portfolios (PAP) in a Bertrand-type international duopoly. Under currency appreciation the firm beta from the depreciating (appreciating) country, decreases (increases). As the...

Net neutrality is believed to prevent the emergence of exclusive online content which yields Internet fragmentation. We examine the relationship between net neutrality regulation and Internet fragmentation in a game-theoretic model that considers the interplay be- tween termination fees,...

We propose a two-sided model with two competing Internet platforms, and a continuum of heterogeneous Content Providers (CPs). We study the effect of a net neutrality regulation on capacity investments in the market for Internet access, and innovation in the market for content. Under the...
