 Despite such examples, it is often unclear whether such theories genuinely take goods and resources to be ontologically related to social entities. Or instead, whether they regard resources to interact causally with social entities, but not to constitute them. Moreover, even in models that include resources, often only individual choices are modeled as having causal powers: resources have no causal import except as mediated by the attitudes and actions of individuals. Even Penrose’s theory of the firm focuses most of its attention on “capabilities”, understood as knowledge and skills of human actors, and subsequent literature derived from Penrose focuses even more on capabilities as the exemplar of resources (e.g., Teece et al. 1997).
