How global are the gains from innovation? When firms operate production plants in multiple countries, technological improvements developed in one location may be shared with foreign sites for efficiency gain. We develop a model that accounts for such transfer, and apply it to measure private...

Do information differences across U.S. physicians contribute to treatment disparities? This paper uses a unique new dataset to evaluate how changes in physician access to a decision-relevant drug database affect prescribing decisions. Our results indicate that doctors using the reference have a...

This paper evaluates the influence of host-country financial development on the global operations of multinational firms. Using detailed U.S. data, we provide evidence that host-country financial development increases entry by multinational affiliates, while also decreasing affiliate sales in...

How do geography and other barriers to the free flow of information shape the rate of knowledge diffusion? To address this question, we develop an empirical model of product discrete choice with Bayesian learning on a social network. Estimating this model using monthly data on the...
