α: calibrated so average coauthorship-adjusted count equals average raw count
This paper extends recent developments in general equilibrium theory and applies them to the problem of measuring the real output of an economy's insurance sector. These developments permit a priced commodity to be a complex incentive-compatible contract. These contracts are not bundles of more basic commodities. These contracts are elementary in the same sense that event-contingent goods deliveries are elementary in the Arrow- Debreu framework.
