Our Hierarchy of Economic Models
We divide economics into neural, behavioral, micro, political, and macro, and evolutionary economics, and everything else a derivative of one of them.
Neural energy limits define the range of behavioral possibilities.
Behavioral patterns define the formation and equilibrium of markets.
Market equilibria define the structure and necessity of political institutions.
Political institutions define the degree of macroeconomic stability and intertemporal coordination.
Macroeconomic stability determines a polity’s evolutionary fitness among competing polities.
Evolutionary feedback selects for institutional and behavioral adaptations that optimize cooperation and resource use.
Evolutionary outcomes feed back to the neural level through prosperity, nutrition, stress, and selection on cognition, completing the loop of adaptation between biology and civilization.

Upward Constraint Flow:
Neural → Behavioral → Micro → Political → Macro → Evolutionary.
Each layer’s limits define the possibility space for the next. -
Downward Selection Flow:
Evolutionary pressures (war, trade, technology, fertility, migration) act as filters on macro- and political systems, rewarding adaptive institutions and punishing maladaptive ones. -
Feedback Closure:
Successful polities alter global constraints—reshaping markets, institutions, and ultimately the neuro-behavioral ecology of their populations through prosperity, nutrition, and education.
This closes the evolutionary loop: neurons → markets → nations → civilizations → neurons.
-
Neural constraints set the bounds of possible cognition (signal detection, valuation resolution, temporal discounting).
-
These bounds generate behavioral regularities — risk aversion, time preference, reciprocity bias.
-
Behavioral regularities, aggregated, produce micro-equilibria (market behaviors).
-
Micro-equilibria, codified through law and norms, generate political economies.
-
Political economies, scaled in time and capital, yield macro-dynamics (growth, debt, inflation).
Each level inherits its constraints from the prior and produces its own incentives for the next.
-
Closure: It ensures all higher claims remain reducible to physically possible processes (no metaphysical free agents).
-
Causality: It keeps every economic claim inside the domain of natural law — energy, time, information, and cooperation.
-
Decidability: It eliminates subjectivist and ideological ambiguity by grounding value in measurable neural operations.
-
Operationality: It allows construction of testable models of preference, learning, and exchange as computational processes.
-
Reciprocity: It reveals that fairness, trust, and reputation are not moral fictions but neural cost-optimization strategies.
