This paper revisits the results of Bloom, Schankerman, and Van Reenen (2013) examining the impact of R&D on the performance of US firms, especially through spillovers. We extend their analysis to include an additional 15 years of data through 2015, and update the measures of firms' interactions...

We characterize the contribution of immigrants to US innovation, both through their direct productivity as well as through their indirect spillover effects on their native collaborators. To do so, we link patent records to a database containing the first five digits of more than 230 million of...

I study the selection and economic outcomes of Italians in Argentina and the US, the two largest destinations during the age of mass migration. Prior cross-sectional work finds that Italians had faster assimilation in Argentina, but it is inconclusive on whether this was due to differences in...
