In this paper, we study the dynamics of usage intensity of second-generation cellular telephony over the diffusion curve. We address two specific questions: First, does information about usage intensity over time allow us to draw conclusions about the underlying drivers of technology diffusion?...

A key property of the World Wide Web is the possibility for firms to place virtually costless links to third-party content as a substitute or complement to their own content. This ability to hyperlink has enabled new types of players, such as search engines and content aggregators, to...

We develop a model of dynamic platform formation under positive platform externalities. Users can switch between an incumbent and entrant platforms, switching opportunities arise stochastically and users can choose whether to accept or reject an opportunity to switch. For homogeneous users, we...

Abstract I model dynamic product design along price and non-price dimensions by a firm in a market with positive network externalities between consumers. In the case of a usage fee, I provide conditions under which the steady state (SS) is unique and show that the introductory price is negative...

The literature of private provision of public goods suggests that incentive to contribute is inversely related to group size. This paper empirically tests this relationship using field data from Chinese Wikipedia, an online encyclopedia. We exploit an exogenous reduction in group size as a...

It has been conjectured that the peer-based recommendations associated with electronic commerce lead to a redistribution of demand from popular products or "blockbusters" to less popular or "niche" products, and that electronic markets will therefore be characterized by a "long tail" of demand...

This paper investigates the importance of network effects in the demand for ethanol-compatible vehicles and the supply of ethanol fuel retailers. An indirect network effect, or positive feedback loop, arises in this context due to spatially-dependent complementarities in the availability of...

Digital products such as movies, music and computer software are protected both by self-help measures such as encryption and copy controls, and by the legal right to prevent copying. We explore how digital rights management and other technical protections a®ect the pricing of content, and...

The purpose of this research is to determine whether Internet telephony has had a negative impact on a country’s telecommunications infrastructure. Using panel data the statistical analysis shows that call-back did not have a negative effect on infrastructure and high income countries...

In this study we examine the antecedents of small independent software vendor (ISV) decisions to join a platform ecosystem. Using data on the history of partnering activities from 1201 ISVs from 1996 to 2004, we find that appropriability strategies based on intellectual property rights and the...
