Asset Prices, Commodity Prices, and Money: A General Equilibrium, Rational Expectations Model
An expected utility-maximizing investor spends his portfolio income on commodities and real balances. Commodity prices and asset payoffs are determined endogenously in general equilibrium. The impact of commodity prices on investor welfare yields surprising relationships among the expected returns required on various assets, for example, real (monetary) disturbances can generate a negative (positive) correlation between inflation and equity payoffs but the expected nominal return on the equity can still be less (greater) than the nominal interest rate.
