“…More broadly, Arend also argues that resources that meet the VRIO criteria are usually identified only ex post, making the explanation circular (empirical tests handle this problem, however); (2) the RBV is mainly used as a convenient framing device and specific implications of the view are seldom tested; (3) the link between resources and performance is not carefully examined, for example, in terms of organizational variables that mediate this link; (4) key resources are hard to measure, particularly those "socially complex" and "tacit" resources that the view often focuses on (e.g., Dierickx & Cool, 1989;Barney, 1991); and (5) the gains from superior resources may not be captured at the firm level-but rather be captured by individual resources (Coff, 1997(Coff, , 1999Lippman & Rumelt, 2003a)-in which case firm performance cannot be the dependent variable.…”
