This volume of the Quantum Economics Textbook Series is devoted to quantum human economics. For more than a century, mainstream economics has imagined its object as a clockwork: an agent is endowed with complete and stable preferences and full information, solves for a unique optimum under given constraints, and the market glides toward equilibrium along a mechanical orbit. With the solemnity of its logic and the beauty of its geometry, this system has become the gateway through which generation after generation enters the discipline. Yet precisely at the foundation of this system the cracks have grown unmistakable. Classical models, at the level of their axioms, delete superposition, interference, entanglement, measurement collapse, and the waxing and waning of coherence; they therefore struggle to accommodate multiple equilibria, path dependence, network effects, herding, critical collapse, and deep uncertainty. The quantum reconstruction offered here does not treat quantum physics as an ornamental metaphor. It re-founds, on the ground of practical ontology, the mathematical and conceptual architecture that quantum theory has forged for a complex world, and transplants it onto quantum human economics. Classical and neoclassical insights are recovered as special cases in the limit of complete decoherence. The whole book unfolds in a unified state–operator–evolution formalism. Each chapter first explains the classical theory thoroughly, then presents an original quantum construction, rigorous derivation, a real historical case, and a dialogue with the great economists; equations are rendered precisely as native Word math objects, and figures and tables are drawn expressly to support the argument. The book suits undergraduates building intuition, graduate students and researchers advancing to the frontier, and practitioners in policy and business.

Abstract Foundations of Quantum Economics unfolds a coherent theoretical thread, replacing the rational-agent premise of mainstream economics with the quantum-person hypothesis: before observation, decision-makers sustain multiple conflicting options encoded in probability amplitudes, and a decision corresponds to collapse triggered by measurement. The book first lays cognitive and mathematical foundations, demonstrating that human judgement inherently exhibits quantum features including superposition, interference and order dependence. Classical probability theory fails for non-commutative economic events, making Hilbert spaces and probability amplitudes indispensable languages for economic inquiry. It then reconstructs causality, information, uncertainty and risk, arguing that economic causes are not uniquely fixed before the collapse of consensus; uncertainty is endogenous to the system, and risk represents the spread of superposed distributions rather than exogenous noise. Built upon this architecture, the work revisits core microeconomic notions such as value, utility, game interaction, supply and demand, property rights, institutions and innovation. All conventional theories are recovered as special limits under zero interference and single eigenstates, while superposition and entanglement furnish fresh explanatory power for economic anomalies. The analysis further expands into macroeconomics, interpreting growth, business cycles, money, fiscal policy, trade and welfare as coherent superposition, phase transition and collapse of collective cognition and consensus, and concludes with the renovation of econometrics and economic governance. The book’s central thesis holds that superposition, interference, observation and collapse are not metaphors borrowed from quantum physics, but intrinsic properties of human cognition and economic practice. Economic realities are not predetermined facts waiting to be discovered; instead, they are generated through human cognition, consensus and practice in the act of measurement. Quantum economics is far more than a cosmetic revision of existing models. It constitutes a shift of research programme, abandoning Laplacian determinism and reconceiving the economy as an open, generative process. The book articulates five interconnected layers: the quantum person as ontological starting point, quantum features of cognition, superposition of collective consensus, endogenous uncertainty, and quantuminformed governance. It reminds researchers and policymakers that economic observation and policy intervention are performative, capable of reshaping the very system they examine. Economics abandons the pursuit of a single, determinate optimum and embraces endogenous uncertainty; policymakers cease to be omniscient system engineers and become prudent stewards of consensus and designers of measurement bases. This volume establishes the unified bedrock for the whole quantum economics series and calls for a new, more honest and realistic economics embedded within the economic process itself.
