Resource-based theory’s central assertion is that valuable and costly to copy resources and capabilities that are also heterogeneously distributed across competing firms can be sources of sustained competitive advantage (Barney 1991). Resource-based theorists have also identified several kinds of resources and capabilities that are likely to meet these criteria for generating sustained competitive advantages, e.g., resources and capabilities that are causally ambiguous (Lippman and Rumelt 1982), socially complex (1986; Barney 1991) tacit and intangible (Itami, 19xx), characterized by asset mass efficiencies and time compression diseconomies (Dierickx and Cool 1989) and so forth.
