56K modems were introduced under two competing incompatible standards. We show the importance of competition between Internet Service Providers in the adoption process. We show that ISPs were less likely to adopt the technology that more competitors adopted. This result is particularly striking...

This paper exploits a unique data set on the payment card industry to study issues associated with network effects and two-sided markets. We show that consumers concentrate their spending on a single payment network (single-homing), although many maintain unused cards that allow the ability to...

Commonly used discrete-choice models such as logit, nested logit, and random-coefficients models place very strong restrictions on how unobservable characteristic space changes with the number of products. We argue (and show with Monte Carlo experiments)that these restrictions can lead to biased...

I exploit a unique data set on the payment card industry to study issues associated with network effects and two-sided markets. I show that consumers concentrate their spending on a single payment network (single-homing), although many maintain unused cards that allow the ability to use multiple...

We exploit scanner data to track payment choice for grocery purchases for a large panel of households over three years. We show that households focus most of their expenditures on one or at most two of these instruments in choosing between using cash, a check, or a card, and they very rarely...

This paper proposes methods for identifying indirect network eects with dynamically optimizing consumers purchasing a durable hardware good and associated software. We apply this model to data drawn from the DVD player and titles markets. We observe model-level prices, sales and characteristics...

Most new consumer durable goods experience rapid declines in prices and improvements in qual- ity, suggesting the importance of modeling dynamics. This paper estimates a dynamic model of consumer preferences for new durable goods with persistent heterogeneous consumer tastes, rational...
