The Foundations of Demand: On the Origin of Markets

This treatise derives a fundamental law of demand from the Theory of Biological Incentives. The central thesis: demand arises exclusively where a product is fitness-promoting and/or enables the human being to collect biochemical reward without the corresponding fitness-enhancing action—agent fraud. Both categories are exhaustive. No product is demanded that falls outside these categories. Preferences are not given quantities. They are expressions of the individual biochemical incentive structure of the human being, shaped by genetics and experience. The market is the aggregation mechanism of these structures. The thesis is supported by neuroscientific studies on the dopaminergic reward system and by market data from five product categories. It is falsifiable: a product that is demanded but is neither fitness-promoting nor enables agent fraud would refute it. No such counterexample currently exists.
