Hayek and Prigogine: Two Paths to Order Without a Designer

Parent article: Complex Systems: Order Without a Designer Origin question: Hayek’s spontaneous order theory and Prigogine’s dissipative structures both describe self-organizing systems far from equilibrium. Has there been a rigorous theoretical integration of these two frameworks?

Friedrich Hayek and Ilya Prigogine arrived at structurally similar ideas from disciplines that did not communicate with each other. Hayek published his ideas on spontaneous order between 1945 and 1973. Prigogine developed the theory of dissipative structures between the 1960s and 1980s. Neither cited the other. Both described how order emerges from interaction under constraints without an external designer.

The difference is in domain and mechanism. Hayek described social order: prices, institutions, language, emerging from the interaction of human agents acting purposefully with local information. The mechanism is the feedback of action results on future actions, mediated by price signals.

Prigogine described physical and chemical order: the Belousov-Zhabotinsky reaction, which generates oscillating patterns in a chemical solution without any instruction; the Bénard convection, where a heated fluid forms perfect hexagonal cells; the structures that emerge in biological systems far from thermodynamic equilibrium. The mechanism is not preference feedback. It is the flow of energy through the system: the dissipation of energy to the environment is the condition that allows internal structure to be maintained and grow in complexity.

The question is whether these are the same phenomenon described in different languages, or distinct phenomena with superficial analogies.

Eric Beinhocker, in “The Origin of Wealth” (2006), was the first to attempt a serious synthesis. He argued that the economy is a complex adaptive system operating far from equilibrium, and that Prigogine’s concepts of dissipation and self-organization apply directly to market dynamics. Firms and products are, in his framework, analogous to dissipative structures: they are maintained only while they consume and dissipate resources from the environment, and their form is determined by environmental conditions more than by any internal design.

W. Brian Arthur at the Santa Fe Institute developed a parallel line, applying ideas from statistical physics to economics. His work on increasing returns and technological lock-in showed that markets with positive feedback exhibit path dependence and multiple equilibria that general equilibrium models do not capture. Stuart Kauffman explored self-organization in biological systems and proposed that the principles of self-organization precede and are independent of natural selection: order emerges first, and selection works on it.

What is still missing is the formal integration. The deepest point of convergence between Hayek and Prigogine is the role of flow. In Prigogine’s systems, the structure is maintained by the flow of energy. In Hayek’s system, the market order is maintained by the flow of information encoded in prices. From my point of view, the most productive hypothesis is that prices are the mechanism by which economic systems dissipate informational uncertainty, in a way that is analogous to how Prigogine’s dissipative structures dissipate thermodynamic entropy.

If that analogy is formal and not merely metaphorical, the stability conditions of a dissipative structure would have direct analogs in the market order. Private property and voluntary exchange would be the gradients that maintain the structure; the price system would be the uncertainty-dissipation mechanism. Suppressing private property or market prices would be analogous to eliminating the temperature gradient that sustains a Bénard cell: the structure collapses not because its components change, but because the condition that sustained it is removed.

Questions worth investigating

Is it possible to formally establish the analogy between thermodynamic entropy dissipation (Prigogine) and informational uncertainty dissipation in price systems (Hayek)? What would the stability conditions of dissipative structures predict about the stability of market orders?
Arthur’s technological lock-in is a path-dependence phenomenon in systems with increasing returns. How does it relate to the Hayekian problem of coordinating expectations, and what does it imply for the design of institutions that must resist capture by incumbent interests?
