The constant-relative-risk-aversion (CRRA) utility function is now predominantly used in quantitative macroeconomic studies. This function, however, is not bounded and thus creates problems when applying the standard tools of dynamic programming. This paper devises a method for "bounding" the...

This paper examines the theoretical foundations of precautionary wealth accumulation in a multi-period model where consumers face uninsurable earnings risk and borrowing constraints. We begin by characterizing the consumption function of individual consumers. We show that consumption function is...

Many claim that fluctuations in US private savings help to create and to sustain global imbalances because of their influence on the current account deficit. To test this claim, this paper investigates the determinants of aggregate household savings using a panel of 18 developed countries for...

This article investigates how wealth and capital gains affected household consumption in the USA in the period 1989-2004. The empirical evidence brought so far by a large literature that investigates the role of wealth shocks on consumption is mixed, due to the low quality of the data more...

This article investigates how wealth affected household consumption in the USA in the period 1989-2007. Previous empirical results are mixed, mostly because of the low quality of the data more readily available. We combine information from the Consumer Expenditure Survey and the Survey of...

How does household wealth influence consumption? The empirical evidence brought so far by the literature is unclear, mostly because of the low quality of the data more readily available: aggregate data, cross sections and panel datasets lacking important variables all present major shortcomings...

This paper presents a dynamic competitive equilibrium model in which heterogeneity in time preferences alone can generate the observed patterns of wealth and income inequality in the United States. This model generalizes the standard deterministic neoclassical growth model by introducing (i) a...

This paper analyzes the optimal consumption behavior of a consumer who faces uninsurable labor income risk and borrowing constraints. In particular, it provides conditions under which the decision rule for consumption is a concave function of existing assets. The current study presents two main...
