Technology diffusion processes are often said to have critical mass phenomena. We apply a model of demand with installed base effects to provide theoretically grounded empirical insights about critical mass. Our model allows us to rigorously identify and quantify critical mass as a function of...

Static demand models for homogeneous network goods give rise to fulfilled-expectations equilibrium demand (FEED) curves, which, contrary to normal demand curves, may be upward sloping at certain intervals. We analyze some, as yet unexplored, properties of the FEED curves. We spell out the...

We examine a technology-adoption game with network effects in which coordination on either technology A or technology B constitutes a Nash equilibrium. Coordination on technology B is assumed to be payoff dominant. We define a technology’s critical mass as the minimal share of users, which is...

We examine a technology adoption game with network effects in which coordination on technology A and technology B constitute a Nash equilibrium. Coordination on technology B is assumed to be payoff-dominant. We define a technology's critical mass as the minimum share of users necessary to make...

This paper uses a typology of industries to summarize and contrast the challenges involved with industry formation and to examine why specific industries were formed in some countries before other ones. The formation of most new industries depends on the introduction of products that provide a...

Critical Mass is a common feature of technology diffusion processes. We develop a structural model of demand with network effects to provide a rigorous definition of critical mass as a function of installed base, price and network effects. Using data from the digital cellular telephony market,...

We model competition between two unregulated mobile phone companies with price-elastic demand and less than full market coverage. We also assume that there is a regulated full-coverage fixed network. In order to induce stronger competition, mobile companies could have an incentive to raise their...

An app store has a two-sided market composed of a developer-side and consumer-side. If the developer-side expands, consumers' willingness to access is increased in the app store market. Therefore, we argue that the expansion of the developer-side is one of the key elements for the success of an...
