In this framework of perfect foresight and market clearing prices, it is possible to make Keynesian assumptions about the rigidity of money wages and the exogeneity of “animal spirits” of investors, to use the standard IS-LM apparatus, and to …

Comparative Statics And Local Indeterminacy In Olg Economies: An Application Of The Multiplicative Ergodic Theorem, John Geanakoplos, Donald J. Brown

Cowles Foundation Discussion Papers

This study is an effort to give a simple measure of the local size of the equilibrium set of OLG economies in which there may be more than one good and more than one consumer per period, and in which the generations may differ across time.
