This chapter focuses on the heterodox micro-macro integrated model of capitalism that is derived from the equations and schemas. It aims to delineate a capitalist economy as a going concern that will serve as the foundation for developing an empirically grounded microeconomic theory of the social provisioning process as well as an empirically grounded model of the economy. The first step in this process is to establish the core structures of a capitalist economy relevant to the social provisioning process and then, secondly, to locate within them the acting organizations and institutions that direct, engage in, or facilitate the economic events that result in social provisioning. The structures help to shape and govern the provisioning process while the organizations and social institutions house the causal mechanisms in which agency is embedded. Social accounting modeling is based on the social accounting matrix (SAM) that is associated with input-output modeling.
