“…As the existing empirical work on organizational boundaries in an R&D context typically utilizes single theories, such as transaction cost efficiency (Athaide and Zhang, 2011;Eng and Wong, 2006), competence (Verona, 1999;Yasuda, 2005), power (Gulati and Sytch, 2007;Mayer and Nickerson, 2005), or organizational identity (Tripsas, 2009), many of the earlier studies neglect the interplay between different boundary conceptions, particularly in the context of R&D relationships. This is surprising because, first, boundary decisions play a particularly important role in R&D relationships, where knowledge asymmetries are great, and second, because of the emphasis placed on the interplay between boundary conceptions by Santos and Eisenhardt (2005, p. 503), who suggested that the conceptions may coevolve and exert a joint impact.…”
