Resumen de The unit root property and optimality: a simple proof
Consider a pure exchange OLG economy under stationary Markov uncertainty with one good and with sequentially complete markets. It is known that an interior stationary equilibrium allocation at which the agents common matrix of intertemporal rates of substitution has a Perron root which is less than or equal to one is conditionally Pareto optimal. We provide a simple and direct proof of this fact.
