Tautology in the resource-based view and the implications of externally determined resource value: Further comments

We counter Barney's challenges and reaffirm the tautology of the elemental business-level resource-based "view" (RBV). We develop a mathematical representation of the REV as a first step toward formalizing its statements. We then explore the implications of our assertion land Barney's agreement) that resource value is indeed determined outside of the REV.
