This paper provides a tractable continuous-time constant-absolute-risk averse (CARA)-Gaussian framework to quantitatively explore how the preference for robustness (RB) affects the interest rate, the dynamics of consumption and income, and the welfare costs of model uncertainty in general...

This paper studies the aggregate dynamics of durable and nondurable consumption under slow information diffusion (SID) due to noisy observations and learning within the permanent income framework. We show that SID can significantly improve the model’s predictions on the joint behavior of...

In this paper we examine implications of model uncertainty due to robustness (RB) for consumption-saving, market price of uncertainty, and aggregate wealth accumulation under limited information-processing capacity (rational inattention or RI) in an otherwise standard permanent income model. We...

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 derives the general equilibrium effects of rational inattention (or RI; Sims 2003, 2010) in a model of incomplete income insurance (Huggett 1993, Wang 2003). We show that, under the assumption of CARA utility with Gaussian shocks, the Permanent Income Hypothesis (PIH) arises in...

In this paper, we examine the joint consumption-portfolio decision of an agent with limited information-processing capacity (rational inattention or RI) in the sense of Sims (2003) within a non-linear-quadratic (non-LQ) setting. Our model predicts that, as processing capacity falls, agents...

In this paper we examine implications of model uncertainty due to robustness (RB) for consumption and saving and the market price of uncertainty under limited information-processing capacity (rational inattention or RI). We first solve the robust permanent income models with inattentive...
