With incomplete markets and numeraire assets, there are open sets of economies such that their equilibrium allocations can be improved upon by a reallocation of period zero endowments. This strengthens the classical results on constrained Pareto ineffciency of equilibria in GEI.

Bei unvollkommenen Märkten und numerairen Vermögen gibt es eine offene Menge an Volkswirtschaften, so dass die Gleichgewichtsverteilung durch eine veränderte Anfangsverteilung verbessert werden kann. Dies stärkt das klassische Ergebnis der eingeschränkten Pareto Ineffizienz von...

In a multi-period, multi-commodity economy with stock markets, we try to extend the work of Drèze (1974) to define the behaviour of the firms. We exhibit first order necessary conditions for a constrained Pareto optimal allocation. The financial constraints lead to non-collinear supporting spot...

This paper studies the efficiency of equilibria in a productive OLG economy where the process of financial intermediation is characterized by costly state verification. Both competitive equilibria and Constrained Pareto Optimal allocations are characterized. It is shown that market outcomes can...
