The macroeconomic analysis of fiscal policy is usually based on one of two canonical models--the Barro-Ramsey model of infinitely-lived families or the Diamond-Samuelson model of overlapping generations. This paper argues that neither model is satisfactory and suggests an alternative. In the...

The theory of intertemporal choice predicts that the cross-sectional variance of the marginal utility of consumption is equal to its own lag plus a constant and a random component. Using general preference specifications and some assumptions about the nature of the random component, we provide...

Consumption is the largest component of GDP. Since the 1950s, the life cycle and the permanent income models have constituted the main analytical tools to the study of consumption behavior, both at the micro and at the aggregate levels. Since the late 1970s the literature has focused on versions...

This paper presents an (S,s) model for automobile consumption and estimates it using a data set of US households. The model allows for unobserved heterogeneity in both the target level and the band width, takes into account the possibility of a zero desired level, constrains the band to be non...

In this paper we show that some of the predictions of models of consumer intertemporal optimization are not inconsistent with the patterns of non-durable expenditure observed in US household-level data. Our results and our approach are new in several respects. First, we use the only US micro...

Only one-fourth of U.S. families own stock. This paper examines whether the consumption of stockholders differs from the consumption of non-stockholders and whether these differences help explain the empirical failures of the consumption-based CAPM. Household panel data are used to construct...

This paper proposes that the time-series data on consumption, income, and interest rates are best viewed as generated not by a single representative consumer but by two groups of consumers. Half the consumers are forward-looking and consume their permanent income, but are extremely reluctant to...

This paper discusses the recent research on the consumption function that has attempted to relax the assumption of certainty equivalence. While there remain many open questions, both theoretical and empirical, it is clear that the assumption of certainty equivalence can be misleading. Under more...

This paper reexamines the consistency of the permanent income hypothesis with aggregate, post-war, United States data. The permanent income hypothesis is nested within a more general model in which a fraction of income accrues to individuals who consume their current income rather than their...
