We develop a simple theoretical framework for thinking about how geographic frictions, and in particular travel costs, shape scientists' collaboration decisions and the types of projects that are developed locally versus over distance. We then take advantage of a quasi-experiment - the...

We study the impact of foreign direct investment (FDI) on total factor productivity (TFP) of domestic firms using a new, representative firm-level data set spanning six countries. A novel finding is that firm-level spillovers from foreign firms to domestic companies can be significantly...

To test for private information leakages from government to corporate executives, we exploitthe 2008-2010 bank bailouts after Lehman's failure using insider trading and political connections.In politically-connected banks, insider buying during the pre-TARP period is associatedwith increases in...

We test how a reduction in travel cost affects the rate and direction of scientific research. Using a fine-grained, scientist-level dataset within chemistry (1991-2012), we find that after Southwest Airlines enters a new route, scientific collaboration increases by 50%, an effect that is...

We study the extent to which eminent scientists shape the vitality of their areas of scientific inquiry by examining entry rates into the subfields of 452 academic life scientists who pass away prematurely. Consistent with previous research, the flow of articles by collaborators into affected...

We quantify the effect of foreign investment on productivity of acquired firms using a new firm-level database that tracks foreign ownership changes. To control for endogenous selection on unobserved firm-level characteristics, we study the differential impact of majority and minority foreign...

We revisit the relationship between foreign investment and productivity of acquired firms. First, we construct a panel firm-level dataset for eight ad- vanced European countries covering domestic and foreign acquisitions together with detailed balance sheet information for the years 1999–2012....
