A Theory of the Consumption Function, With and Without Liquidity Constraints (Expanded Version)

Carroll, Christopher D. - 2001

This paper argues that the modern stochastic consumption model, in which impatient consumers face uninsurable labor income risk, matches Milton Friedman's (1957) original description of the Permanent Income Hypothesis much better than the perfect foresight or certainty equivalent models did. The...

Precautionary Saving and the Marginal Propensity to Consume out of Permanent Income

Carroll, Christopher D. - 2001

The budget constraint requires that, eventually, consumption must adjust fully to any permanent shock to income. Intuition suggests that, knowing this, optimizing agents will fully adjust their spending immediately upon experiencing a permanent shock. However, this paper shows that if consumers...

Buffer-Stock Saving and the Life Cycle/Permanent Income Hypothesis

Carroll, Christopher D. - 1996

This paper argues that the typical household's saving is better described by a "bufferstock" version than by the traditional version of the Life Cycle/Permanent Income Hypothesis (LC/PIH) model. Buffer-stock behavior emerges if consumers with important income uncertainty are sufficiently...

How Important is Precautionary Saving?

Carroll, Christopher D. - 1995

We estimate the fraction of the wealth of a sample of PSID respondents that is held because some households face greater income uncertainty than others. We first derive an equation characterizing the theoretical relationship between wealth and uncertainty in a buffer-stock model of saving. Next,...

The Nature of Precautionary Wealth

Carroll, Christopher D. - 1995

This paper uses the Panel Study of Income Dynamics to provide some of the first direct evidence that wealth is systematically higher for consumers with greater income uncertainty. However, the apparent pattern of precautionary saving is not consistent with a standard parameterization of the life...

Dissaving by the Elderly, Transfer Motives and Liquidity Constraints

Ando, Albert - 1993

Two explanations have been proposed for the observed slowness of wealth decumulation by the elderly in the literature: the precautionary saving induced by (uninsurable) uncertainty about the time of death or by the possibility of major catastrophes in old age that require large outlays; the...

Wealth Depletion and Life Cycle Consumption by the Elderly

Hurd, Michael D. - 1990

The objective of the work reported in this paper is to find if the consumption data from the six waves of the Retirement History Survey are consistent with the life cycle hypothesis of consumption and to test the importance of a bequest motive for saving. The 12 data items which are used cover...

Precautionary Saving and the Marginal Propensity to Consume

Kimball, Miles S. - 1990

The marginal propensity to consume out of wealth is important for evaluating the effects of taxation on consumption, assessing the possibility of multiple equilibria due to aggregate demand spillovers, and explaining observed variations in consumption. It is also a component of the interest...

Saving and Liquidity Constraints

Deaton, Angus - 1989

This paper is concerned with the theory of saving when consumers are not permitted to borrow, and with the ability of … such a theory to account for some of the stylized facts of saving behavior. When consumers are relatively impatient, and …

Intergenerational Transfers and Savings

Kotlikoff, Laurence J. - 1987

savings? Is it primarily accumulation for retirement as claimed by Albert Ando, Richard Brumberg, and Franco Modigliani in … their celebrated Life Cycle Model of Savings? Is it primarily intentional accumulation for intergenerational transfers? Or … is it primarily precautionary savings, much of which may be bequeathed because of imperfections in annuity markets? This …
