“…Literature reviews, theoretical, qualitative and descriptive papers, and quantitative works that do not provide effect size (e.g., Mack, 2014-a;Mack & Grubesic, 2009;Tranos & Mack, 2016) are thus excluded. Moreover, some studies that use an outcome variable that we judge to be insufficiently related to firm location, such as the amount of investment or the share of nonfarm proprietors (Cumming & Johan, 2010;Conley & Whitacre, 2016), are excluded. Finally, for each selected study, we include only estimates that meet all criteria (e.g., when studies assess the effect of broadband on both firm location and employment, we include only estimates for firm location).…”
