Entropy Economics: The Living Basis of Value and Production (published in 2025 by the University of Chicago Press) by James K. Galbraith and Jing Chen directly tackles the exact core problem we just discussed. It attempts to completely dismantle the foundation of neoclassical economics and rebuild it from the ground up using the laws of thermodynamics and evolutionary biology.
The book is an ambitious, provocative effort to force economics to behave like a natural science rather than an idealized mathematical sandbox.
1. The Core Premise: The Death of "Equilibrium"Mainstream economics is obsessed with the concept of equilibrium—the idea that markets are self-correcting systems that naturally balance supply and demand to achieve a steady state.
Galbraith and Chen argue that this is a dangerous mathematical fiction that directly contradicts modern physics.
In thermodynamics, the only state of perfect, unchanging equilibrium is thermodynamic equilibrium, which is a polite way of saying death.
Living organisms, ecosystems, and human economies are all open, non-equilibrium systems. To stay alive and organized, they must constantly consume low-entropy energy (food, oil, sunlight) and dissipate high-entropy waste (heat, carbon, pollution) into their surroundings.
By replacing the "equilibrium" myth with the second law of thermodynamics, the authors argue that an economy is naturally prone to decay, instability, and rising disorder unless it is actively maintained.
2. Redefining Value and ProductionThe book introduces an entirely new biophysical framework for the two central pillars of economic thought:
The Entropy Theory of ValueInstead of value being derived purely from subjective human utility or abstract "labor hours," Galbraith and Chen anchor value in physical scarcity and information entropy. Mathematically, their value function relies on a simple logarithmic scale:
$$\text{Value} \propto \log_b(\text{Scarcity})$$Where scarcity dictates the input, and the base ($b$) represents the number of suppliers (the market structure). This allows them to cleanly integrate the physics of scarcity with the political reality of monopoly power. Value isn't an invisible hand naturally finding a balance; it is a physical constraint manipulated by whoever controls the low-entropy resource.
Biophysical Production TheoryMainstream production functions (like the famous Cobb-Douglas model) treat capital and labor as independent inputs that can seamlessly substitute for one another.
[Traditional Economics] Money / Capital <-- Interchangeable --> Labor
[Entropy Economics] Low-Entropy Energy/Resources --> Real ConstraintsThe authors argue this is a physical impossibility. Capital (machinery) and labor are just mechanisms used to direct and transform energy. They frame production around a highly realistic business model dominated by fixed costs vs. variable costs.
Advanced, highly ordered civilizations require massive upfront, low-entropy investments (high fixed costs) to build infrastructure.
Once built, they run efficiently (low variable costs).
However, if the underlying low-entropy resources become scarce or too expensive, the system can no longer sustain its high fixed costs, triggering structural decline.
3. The Necessity of RegulationIn standard economics, government intervention or regulation is treated as an annoying "distortion" of an otherwise perfect market.
In Entropy Economics, regulation is a biological necessity. Just as a living body requires homeostatic regulation (like a heart rate or body temperature controller) to keep from flying into entropic chaos, an economy requires strict governance, institutional boundaries, and independent regulators to manage resource flows and keep economic inequality from tearing the social fabric apart.
The Book's Provocative ConclusionsBecause the book respects physical limits, its look into the future is remarkably sobering. Galbraith and Chen use their biophysical models to challenge popular assumptions about the green transition:
Skepticism of Renewable Tech: They note that "solutions" like electric vehicles or massive tidal arrays do not escape the laws of entropy. Building their complex infrastructure and batteries requires an intense extraction of highly finite, low-entropy mineral resources (lithium, copper), shifting the entropic burden rather than eliminating it.
The Squeeze of Complexity: As resources become scarcer and more degraded (higher entropy), society will have to spend a larger portion of its total energy just to maintain existing infrastructure.
Ultimately, the book suggests that a world bound by thermodynamic reality will eventually mean a shift toward lower fixed costs, smaller scale, and a necessary abandonment of the infinite-growth paradigm. It provides the exact mathematical and physical foundation that historical resource economics lacked when it naively predicted the $40 oil ceiling.
