This paper presents a small-scale agent-based extension of the so-called neo-Kaleckian model. The aim is to investigate the emergence of Harrodian instability in decentralized market economies. We introduce a parsimonious microfoundation of investment decisions. Agents have heterogeneous...

Can boundedly rational agents survive competition with fully rational agents? The authors develop a highly nonlinear heterogeneous agents model with rational forward looking versus boundedly rational backward looking agents and evolving market shares depending on their relative performance....

A recent literature introduces autonomous demand as the driver of long-run economic growth and as a stabilizing force that tames Harrodian instability. The argument is unconvincing. The stabilizing effect is modest for plausible parameter values and, more importantly, it is questionable whether...

Sraffian supermultiplier models, as well as Kaleckian distribution and growth models making use of non-capacity creating autonomous demand growth in order to cope with Harrodian instability, have paid little attention to the financial side of autonomous demand growth as the driver of the system....

Savings behaviour seems to exhibit heterogeneity across nations, and within nations, too. Large changes in saving rates have been observed in the last decades that can be viewed as signs of the arbitrariness of saving. There is a long tradition in the savings literature that separates people...
