The effects of (private, small-scale) piracy on the pricing behavior of producers of information goods are studied within a unified model of vertical differentiation. Although information goods are assumed to be perfectly horizontally differentiated, demands are interdependent because the...

The effects of (private, small-scale) copying on the pricing behavior of producers of information goods are studied within a unified model of vertical di¤erentiation. Although information goods are assumed to be perfectly horizontally differentiated, demands are interdependent because the...

In this paper, we explore the strategic decision of an incumbent to open a proprietary technology platform in order to allow same-side co-opetition in a market characterized by network effects. We propose a game-theoretic model that analytically conceptualizes the interplay among the degree of...
