Notes on the Suboptimality Result by J. D. Geanakoplos and H. M. Polemarchakis (1986)
J. D. Geanakoplos and H. M. Polemarchakis (1986) prove the generic constrained suboptimality of equilibrium allocations in two period economies with incomplete markets. They perturb asset prices at equilibrium when the degree of market incompleteness equals one. However, since prices are not fundamentals that parameterize the economy, a generic result cannot be obtained in such a way. In these notes we provide complete and detailed version of their proof in which the arguments do not depend on the dimension of the market incompleteness and in which utilities and endowments are perturbed.
