Abstract for: Capital-Human (In)stabilities: A Constructive Framework for Self-organized, dissipative Macroeconomics Models

This article introduces a comprehensive model that encapsulates capital's physical and economic nature, addressing the complex interplay of ecological, economic, and societal dynamics and an ensemble of extensions with their effects. Emphasizing self-organization between capital investment and its services, our framework relies on a double stock-flow consistency, metabolic processes, and behavioral heuristics. We demonstrate its robustness as a foundation with a justification for each hypothesis choice, encompassing dynamics related to debt and inventory. The core dynamics emerge as closed cycles between employment and wage share that align with an extended (Goodwin, 1967) model. We discuss the interest of such self-organizing approaches for the challenge of post-growth studies. The economic system adapts wages in a deteriorating environment to maintain consistent mean growth and employment. We systematically explore how parameter variation and hypothesis substitution impact system equilibrium position and stability for 25 complementary phenomena that we describe and mathematically analyze. We show that, even in its two-dimensional form, the system can exhibit limit cycles with an unstable equilibrium. We conclude that an out-of-equilibrium, process-based perspective is essential, advocating for a closed cycle dynamical core as an initial framework for clarity, quantitative, coupling studies. Furthermore, we discuss the potential for extending this archetype with disaggregation to address dynamics related to inequality and multisectoral productive capital in a changing world
