Elementary Microeconomics of the Talmudic Rule
This paper takes a look at the Talmudic rule aka the 1/N rule aka the uniform investment strategy from the viewpoint of elementary microeconomics. Specifically, we derive the cardinal utility function for a Talmud-obeying agent which happens to have the Cobb-Douglas form. Further, we investigate individual supply and demand due to rebalancing and compare them to market depth of an exchange. Finally, we discuss how operating as a liquidity provider can benefit the Talmud-obeying agent with every exchange transaction in terms of the identified utility function.
