“…However, extant studies on knowledge-sourcing and firm performance, while recognizing that CVC investments are often used as technology-sourcing instruments in conjunction with other external knowledge-sourcing strategies, have juxtaposed the various sourcing strategies without considering the potential synergetic or detrimental effects that their joint engagement could bring about (e.g., Keil et al, 2008;Rothaermel and Hess, 2007;van de Vrande et al, 2011;Wadhwa and Kotha, 2006;Wadhwa et al, 2015). In this study, we take a portfolio perspective of CVC investments, following recent contributions to the CVC literature (Yang, Narayanan and De Carolis, 2014;Wadhwa et al, 2015;Matusik and Fitza, 2012), and extend this perspective to focus on firms' broader knowledge exploration portfolio consisting also of technology alliances.…”
