“…Secondly, while the pathways through which higher education activities can act to raise local economic development are clear, empirical evidence documenting the existence of a causal relationship is still scarce. To date, to the best of our knowledge, few papers have explicitly considered the direct link between university presence and economic performance (Abel & Deitz, 2012;Agasisti, Barra, & Zotti, 2019;Aghion, Boustan, Hoxby, & Vandenbussche, 2009;Andersson, Quigley, & Wilhelmson, 2004;Cantoni & Yuchtman, 2014;Cermeño, 2019;Kantor & Whalley, 2014;Kantor & Whalley, 2019;Valero & Van Reenen, 2019). Indeed, OLS estimates might not show a causal relationship if, in turn, local economic development at least in part determines universities' production of graduates (for instance, changes in economic conditions could lead to an increase in the demand or supply of graduates).…”
