As Internet-based commerce becomes increasingly widespread, large data sets about the demand for and pricing of a wide variety of products become available. These present exciting new opportunities for empirical economic and business research, but also raise new statistical issues and...

We present a model of dynamic monopoly pricing for a good that displays network effects. In contrast with the standard notion of a rational-expectations equilibrium, we model consumers as boundedly rational, and unable either to pay immediate attention to each price change, or to make accurate...

In this paper, we analyze how different dimensions of a seller's reputation affect pricing power in electronic markets. Given the interplay between buyers' trust and sellers' pricing power, we use text mining techniques to identify and structure dimensions of importance from feedback posted on...

The effective management of digital rights is the central challenge in many industries making the transition from physical to digital products. We present a new model that characterizes the value of these digital rights when products are sold both embedded in tangible physical artifacts, and as...

We present a framework for measuring software quality using pricing and demand data, and empirical estimates that quantify the extent of quality degradation associated with software versioning. Using a 7-month, 108-product panel of software sales from Amazon.com, we document the extent to which...

This paper presents a model of local network effects in which agents connected by a social network each value the adoption of a product by a heterogeneous subset of other agents in their 'neighborhood', and have incomplete information about the structure and strength of adoption...

This paper presents an analysis of competition in wireless telecommunications that models the interdependence between spectrum availability, network infrastructure deployment, the generation of transmission technology, average traffic levels and service quality. We show that the constraints on...

This paper studies competition in the presence of digital convergence, a phenomenon that has been observed in a variety of information technology industries: handheld computing, telecommunications, consumer electronics, networking, residential broadband and broadcast video, among others. Digital...
