In this paper we generalize Magill and Shafer (1990) analysis of generically complete markets in the presence of open ended horizon. Doing this we are faced with difficulties specific to the presence of infinitely many periods. Until now these difficulties did not allow any satisfactory...

We prove the existence of monetary equilibrium in a finite horizon economy with production. We also show that if agents expect the monetary authority to significantly decrease the supply of bank money available for short term loans in the future, then the economy will fall into a liquidity trap...

We consider dynamic stochastic economies with heterogeneous agents and introduce the concept of uniformly self-justified equilibria (USJE)---temporary equilibria for which forecasts are best uniform approximations to a selection of the equilibrium correspondence. In a USJE, individuals'...

This paper documents the macroeconomic effects of changes in downpayment requirements on mortgage loans in a model where investment is undertaken by collateral- constrained agents. I find that a permanent tightening in lending standards substantially lowers aggregate spending in the short run...

In a multiperiod economy with incomplete markets and assets that exhibit a payoff depending on price history, we show that one need not perturb back office and settlement feature of assets to get endowment generic existence of an equilibrium. We exhibit a class of assets -transverse assets - and...

When infinite-lived agents trade long-lived assets secured by durable goods, equilibrium exists without any additional debt constraints or uniform impatience conditions on agents' characteristics. Also, price bubbles are absent when physical endowments are uniformly bounded away from zero.

We consider a model with real assets and restricted participation described by household specific price dependent short selling constraints. We show existence of equilibria for all elements in an explicitly characterized large subset of the set of economies.

It is well known that, under uniform impatience, positive net supply assets are free of bubbles for non-arbitrage kernel deflators that yield finite present values of wealth. However, this does not mean that prices cannot be above the series of deflated dividends for the deflators given by the...
