We advance the resource dependence literature on appropriation of organizational resources by powerful partners, focusing on political ties. Using a unique emerging market case of a venture with political ties, we advance theory by unpacking how political connections can hurt the organization by increasing the permeability of organizational boundaries. Our extensions highlight the crucial role of control mechanisms for politically connected organizations.Keywords Organizational boundary . Resource dependence . Political ties . PermeabilityOrganizations commonly seek to create linkages with external parties to access key resources and opportunities (Hitt, Ahlstrom, Dacin, Levitas, & Svobodina, 2004), especially in emerging economies (Ahlstrom, Young, Nair, & Law, 2003). Yet these linkages also carry some costs and risks (Lin & Si, 2010). Researchers employing resource dependence theory (RDT) in particular have shown that risks are prevalent when there is a power imbalance, as powerful partners may appropriate organizational resources (Casciaro & Piskorski, 2005;Emerson, 1962;Gulati & Singh, 1998;Pfeffer & Salancik, 1978). Although considerable research has advanced our knowledge of the conditions under which organizations seek partnerships (e.g., Hillman, Withers, & Collins, 2009;Katila, Rosenberger, & Eisenhardt, 2008), we know much less about the mechanisms by which powerful partners appropriate resources (Mellahi, Frynas, Sun, & Siegel, 2016;Xia, 2011) and, in turn, how weaker organizations can seek to protect themselves (Katila et al., 2008). This is important as smaller firms increasingly enter new markets and must partner with larger (and sometimes) state linked partners creating relationships that need to be carefully managed (Young, Ahlstrom, Bruton, & Rubanik, 2011). How companies can protect themselves against appropriation is a relatively recent but important research topic within RDT, especially in the context of powerful political ties, an area where capture by powerful partners is particularly acute. Political ties link the organization to the government with potentially beneficial effects (Hillman, 2005), but they cannot be fully controlled and may create their own problems such the extraction of rents or derailing strategy (Fan, Wong, & Li, 2007;Lin & Si, 2010;Shleifer & Vishny, 1994;Siegel, 2007;Sun, Hu, & Hillman, 2016;Sun, Mellahi, & Wright, 2012). A new generation of RDT research suggests this problem is particularly salient in emerging economies, where new ventures often need powerful political ties to acquire resources such as licenses to operate and build legitimacy, but this can yield a power imbalance that may stimulate appropriation of firm resources (Mellahi et al., 2016).A few recent studies address the question how appropriation works. For instance, Sun et al. (2016) detailed how substantial shareholders colluded with political ties to expropriate minority shareholders, but they focus mostly on well-established publicly listed companies.
