Competition in Digital Markets

This thesis contains three essays on different topics related to competition in digital markets. The first essay analyzes the effects of interoperability on price competition in a market with network effects. It looks at a market in an early stage of development before the monopoly is entrenched. The second essay studies the roles of complementarity and economies of scope in conglomerate mergers involving a digital ecosystem. It shows that these two characteristics lead to foreclosure in the long run. The last essay investigates the effect of improved information, in the form of more accurate product recommendations, on price competition.
