We study monopoly and duopoly pricing in a two-sided market with dispersed information about users' preferences. We first show how the dispersion of information introduces idiosyncratic uncertainty about participation rates and how the latter shapes the elasticity of the demands and thereby the...

We study monopolistic and competitive pricing in a two-sided market where agents have incomplete information about the quality of the product provided by each platform. The analysis is carried out within a global-game framework that offers the convenience of equilibrium uniqueness while...

We analyze a dynamic model in which firms and consumers choose to adopt one of two technologies or delay their adoption. Adoption allows agents to trade with other adopters of the same technology. We show that there is an inefficient equlibrium in which THORN;rms differentiate across standards...

This paper estimates the importance of network effects in the market for Yellow Pages. I estimate three simultaneous equations: consumer demand for usage of a directory, advertiser demand for advertising and a publisher's first-order condition (derived from profit-maximizing behaviour)....

This paper specifies and estimates a dynamic model of consumer preferences for new durable goods with persistent heterogeneous consumer tastes, rational expectations about future products and repeat purchases over time. Most new consumer durable goods, particularly consumer electronics, are...

Previous work studying the age distribution of citations for patents relies on functional form assumptions to address the co-linearity between the birth year, citation year, and age. This paper proposes a non-parametric identification strategy that uses the lag between application and grant as a...

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