The economy is a circulatory system. GDP measures the wrong variable.

Almost everyone agrees GDP is the wrong measure, and nothing has changed in ninety years. The persistence is structural rather than intellectual: at Bretton Woods GDP became the accounting language of international finance, so alternatives failed not by being worse but by being optional. A replacement must be adoptable without anyone's permission — which points at one pool of philanthropic capital where the claim is immediately testable.

Why volume is the wrong measure

An economy that moves a great deal of money between a small number of hands is not healthy, and an accounting system that adds up transactions cannot tell the difference. Velocity and depth of flow are what determine whether value reaches anyone, and neither appears in the headline figure.

The consequence is not academic. Policy optimises what it measures, so a measure that rewards volume produces institutions that maximise throughput and are surprised when the system underneath them thins out.

The unit of analysis is the relationship

Most economics takes the individual as the unit and treats relationships as frictions. Circulatory economics inverts that: the relationship is where value actually moves, and the individual is the node it moves between. That single change is what makes the gift, the grant and the loan comparable objects rather than three separate literatures.

Names the paradigm. Unifies R*, GIC, and AoE into a single claim about what economies are and how they should be measured. The capstone paper of the entire corpus.
