Complex realist economics: toward an ontology for an interested pluralism.

Contemporary economic theory has entered into an era of unprecedented pluralism. Convincing arguments have been presented for the integration of this pluralism, the possibilities for which however rest on questions of ontology. This paper looks at two hubs of pluralist research, complexity economics and heterodox economics, to evaluate the possibilities for an integration. Complexity economics constitutes an ontological broadening of neoclassicism, but is based on an implicit and incomplete social ontology. Heterodox economics has been argued to be systematized by a critical realist ontology, but has been criticized for limits in the operationalization of this ontology. An ontological merge is sketched, resulting in Complex Realist economics, which is argued to be capable of resolving the 'confused state' of complexity economics, providing the heterodox tradition with the necessary methodologies to study the phenomena that it theorizes, and constituting a consistent ontological foundation for an 'interested pluralism'.
