International business travel: an engine of innovation? (2014, unknown): “ [| ̂] = exp [ ln +  ln +  +  +  + ̂ + ]  (4)”
Urban Economics and Entrepreneurship (2009, unknown): “Recent contributions include Agrawal et al. (2008), Gerlach et al. (2010), and Simonen and McCann (2008).”
Buy local? The geography of venture capital (2010, background): “Evidence of geographic knowledge spillovers is found in biotechnology by Zucker, Darby, and Brewer (1998) and more recently by Agrawal, Kapur, and McHale (2008), who document the importance of geographic proximity for inventors using patent data.”
Roads and Innovation (2017, unknown): “Agrawal, Kapur, and McHale (2008) provide evidence that social/ethnic proximity substitutes for geographic proximity in terms of its influence on regional knowledge flow patterns, suggesting that the dispersion of socially proximate individuals maximizes regional innovation.”
Not Invented Here? Innovation in Company Towns (2009, background): “Knowledge externalities appear to be quite strongly localized (Jaffe et al. (1993),Agrawal et al. (2008)), likely due to their tacitness which makes transfer via face-to-face interactions relatively less costly (Arrow (1962), Polanyi (1966)), hence con- 2 ferring benefits to co-location and…”
Same difference? Minority ethnic inventors, diversity and innovation in the UK (2015, methodology): “By contrast, Agrawal et al. (2008) find that physical location is up to four times more important for knowledge diffusion than co-ethnic connections.”
The Supply Side of Innovation: H‐1B Visa Reforms and U.S. Ethnic Invention (2010, background): “Understanding these mechanisms is important as immigration policies influence firms, universities, and other institutions differently.(2)”
Brain drain or brain bank? The impact of skilled emigration on poor-country innovation (2008, background): “Agrawal et al. (2008) show that both co-location and co-ethnicity support knowledge flows, with a negative interaction between the two.”
Breakthrough Inventions and Migrating Clusters of Innovation (2009, background): “This is because, holding xed the number of breakthrough inventions, the ratio (1) is larger for places with smaller shares of overall patenting.”
