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 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...

A disturbing feature of the conventional objective function for intertemporal decisions under uncertainty is that the agent's attitudes toward intertemporal substitution and risk aversion are entangled. This paper shows that, in contrast to common perception, the two attitudes can be completely...

The more a country saves, the less it invests as a share of saving. We build a “store-or-sow” model of growth with precautionary saving and investment to study the nonlinear relationship between investment and saving. We contend that income volatility is an important variable for explaining...

This paper studies the factors that can generate the puzzling saving phenomenon in the US: 1) Starr-McCluer (1996) finds that households covered by private health insurance save more than comparable households without coverage, even when controlling for other variables. 2) The asset holding...

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...

Auctions often involve goods exhibiting a common knowledge ex-post risk that is independent of buyers’ private values or their signals regarding common value components. Esö and White (2004) showed theoretically that ex-post risk leads to precautionary bidding for DARA bidders: Agents reduce...

This study establishes necessary conditions for Almost Stochastic Dominance criteria of various orders. These conditions take the form of restrictions on algebraic combinations of moments of the probability distributions in question. The relevant set of conditions depends on the relevant order...
