This paper analyzes the role of individual heterogeneity in the diffusion of a network technology. Using a detailed data set on the adoption of a new videoconferencing technology within a firm, we estimate a structural model of technology adoption and use. We find that employees have significant...

We estimate the demand for a videocalling technology in the presence of both network effects and heterogeneity. Using a unique dataset from a large multinational firm, we pose and estimate a fully dynamic model of technology adoption. We propose a novel identification strategy based on...

In-kind public transfers are commonly targeted based on observable characteristics of potential recipients. This paper argues that when the subsidized good is provided by imperfectly-competitive firms, targeting can give rise to a “demographic externality,” creating unintended redistribution...

A basic problem in applied settings is that different parameters may apply to the same model in different populations. We address this problem by proposing a method using moment trees; leveraging the basic intuition of a classification tree, our method partitions the covariate space into...
