We explore how members of a collective pension scheme can share inflation risks in the absence of suitable financial market instruments. Using intergenerational risk sharing arrangements, risks can be allocated better across the various participants of a collective pension scheme than would be...

This note extends the finding of Benhabib and Rusticchini (1994) who provide a class of SDGE models, whose solution is characterized by a constant savings rate. We show that this class of models may be interpreted as a standard representative agent SDGE model with costly adjustment of capital...

This paper examines a dynamic model of mutual insurance when households can also engage in self-insurance by storage. This mutual insurance is informal as it is assumed that there is no enforcement mechanism, so any mutual insurance arrangements must be self-enforcing. It is shown how...

We examine the effects of decreasing down payment requirements on consumption volatility within a model which generalizes the standard buffer-stock model of saving to accommodate durables, nondurables and a collateralized liquidity constraint. We consider both a version of the model without...

We analyze a dynamic moral hazard setting, in which agents can borrow and lend and their decisions about effort, consumption and savings are private information. In contrast with previous findings, we show that as long as agents do not have perfect control over publicly observable outcomes, the...

In this note, we consider in discrete time the Ramsey growth model without discounting under stochastic uncertainty modelled by Markov processes. To make the model computationally tractable we shall consider finite state approximations of the original model. Properties of policies maximizing...

Contrary to the usual presumption that welfare is maximized if consumers behave rationally, we show in a two-period overlapping generations model that there always exists a rule of thumb that can weakly improve upon the lifecycle/permanent-income rule in general equilibrium with irrational...
