Developing a simple model of the content and access industries in the digital era, we show that, given the positive consumption externality from entertainment content (music, video) on access networks and playing devices (fixed broadband, 3G mobile, digital players, etc.), both content and...

Most digital goods have a modular design; that is, they consist of complementary and distinct building blocks, called modules. Modular product design, in contrast to integrated (or integral) design, enables alteration of a specific module that is usually assigned for a specific function without...

We consider an unregulated incumbent who owns a broadband infrastructure and decides on how much access to provide to a potential entrant. The level of access determines the amount of investment the entrant needs to undertake to enter the market, and the intensity of post-entry competition. We...

Abstract In this paper, we analyze the impact of cooperation on R&D investments in a two-sided market, where platforms compete in quantities. We show that if indirect externalities are of a moderate magnitude, the threshold degree of spillovers above which cooperation spurs R&D investments and...

Abstract In this paper we propose a model where consumer personal data have multidimensional characteristics, and are used by platforms to offer ad slots with better targeting possibilities to a market of differentiated advertisers through real-time auctions. A platform controls the amount of...
