This paper analyses a model of overlapping generations in which agents who do not participate in th elabor market are unable to borrow. Thus an increase in a fully funded pension raises aggregate savings even with a fixed participation rate since private savings are not crowded out one-for-one....

We show that extrinsic or non-fundamental uncertainty influences markets in a controlled environment. This work provides the first direct evidence of sunspot equilibria. These equilibria require a common understanding of the semantics of the sunspot variable, and they appear to be sensitive to...

This note shows that there are monetary equilibria in the model of overlapping generations that are in the core. Some equilibria have positive stocks of outside money in every generation. These equilibria are thus self-enforcing, and introducing money into an economy need not be tantamount to...
