Frågorna om effekter på den ekonomiska tillväxten och dess olika komponenter (framför allt konsumtion, investeringar och exporter) är centrala i post-keynesiansk nationalekonomi. Sedan 1990 förs diskussionen framför allt utifrån Bhaduri och Marglins modell av löneledd och vinstledd tillväxt. Engelbert Stockhammer ger i en ny artikel, "Wage-led versus profit-led demand: what have we learned? A Kaleckian–Minskyan view", en översikt över de nyare debatterna. Han fokuserar på mötena mellan efterföljare till Michal Kalecki (1943), å den ena sidan, och efterföljare till Richard Goodwin (1967) å den andra sidan. Stockhammer sammanfattar sitt argument så här:
(1) "while neo-Kaleckians interpret the model as a medium-term, partial-equilibrium goods market model, neo-Goodwinians are interested in the interaction of demand and distribution and regard the model as a long-run model with short-run cycles."
(2) "we elaborate a Kaleckian–Minskyan view of the economy as characterised by a wage-led demand regime and cycles driven by financial fragility. We argue that many of the reported results may suffer from omitted variable bias as they do not include financial control variables. We summarise evidence that, at least in the recent past, financial effects on demand have been much larger in size than distribution effects. We also argue that a wage-led Minsky model with a reserve-army distribution function does give rise to pseudo-Goodwin cycles."
