“…Estimates for the latter period are authors' estimates based on the American Community Survey 2009-2013 5-Year Estimates(Ruggles et al, 2010).3 Examples of such studies includeBellini, Ottaviano, Pinelli, and Prarolo (2013) andLee (2015). It is beyond the scope of this paper to catalog this literature exhaustively, but interested readers are directed to the review articles cited in the previous section.4 See also closely related work on the multiscalar relationship of diversity to innovation, with more mixed results(Brunow & Stockinger, 2015;Nathan, 2016;Østergaard & Timmermans, 2015).5 There is important related work on the impacts of high-skill immigrants on productivity, wages, employment, and innovation; seeKerr (2013) andLewis and Peri (2014) for detailed reviews. Again, there is closely related work with innovation as the outcome of interest(Brunow & Stockinger, 2015;Ozgen, Nijkamp, & Poot, 2015;Ozgen, Peters, Niebuhr, Nijkamp, & Poot, 2014;Parrotta, Pozzoli, & Pytlikova, 2014;Solheim & Fitjar, 2016).…”
