Keynes, Kalecki and Minsky -Post Keynesian champions in comparison or: joining forces, horses for courses or the necessity of discrimination?

The effort to pluralise economics requires informed choices about paradigms, understanding their features and affiliations. Theories must be compared based on their paradigmatic localisation. A hermeneutic analysis challenges the view that Keynes, Kalecki, and Minsky share a unified Post Keynesian paradigm. Kalecki's closed system contrasts with Keynes's open system, suggesting Kalecki may align more with new-Keynesian models. Minsky, however, shares Keynes's open system ontology. This indicates that 'Post Keynesianism' may misleadingly suggest coherence where significant differences exist.
