We are interested in the occurrence of expectation-driven fluctuations of a rational bubble and the (de-)stabilizing role of monetary policy. Our explanation of fluctuations is based on credit market imperfections. For this purpose, we consider an overlapping generations exchange economy where...

We explore the existence of endogenous fluctuations with a rational bubble and the stabilizing role of fiscal and monetary policies. Consumers' credit constraints, the role of collateral and a portfolio choice are the key ingredients of our analysis. We consider an overlapping generations model...

In this paper, we study the equilibrium dynamics of an overlapping generations model with capital, money and cash-in-advance constraints. At each period, the economy can experience two different regimes: either the cash-inadvance constraint is binding and money is a dominated asset, or the...

This paper examines the growth and welfare effects from an increase in the rate of money supply in an Ak type growth model with a relative wealth-enhanced social status motive, production externalities, and liquidity constraints. When only consumption is constrained by liquidity, fast money...

This paper is a study of money in overlapping generations models with cash-in-advance constraints. We first offer a brief review of different features of the cash-in-advance constraint. Then we propose a general formulation and study the neutrality of money. We show that both neutrality and...
