This paper studies the consumption-savings behavior of households who have risk-sensitive preferences and suffer from limited information-processing capacity (rational inattention or RI). We first solve the model explicitly and show that RI increases precautionary savings by interacting with...

In this paper we examine the effects of model misspecification (robustness or RB) on international consumption correlations in two otherwise standard small open economy models: one with perfect state observation and the other with imperfect state observation. We show that in the presence of...

In this paper we examine the effects of model misspecification (robustness or RB) on international consumption correlations in an otherwise standard small open economy model with endogenous capital accumulation. We show that in the presence of capital mobility in financial markets, RB lowers the...

In this paper we examine how model uncertainty due to the preference for robustness (RB) affects optimal taxation and the evolution of debt in the Barro tax-smoothing model (1979). We first study how the government spending shocks are absorbed in the short run by varying taxes or through debt...

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 steady...

This technical paper considers ways to capture uncertainty in the context of so-called "state-space" models. ; State-space models are powerful tools commonly used in macroeconomics, international economics, and finance. State-space models can generate estimates of an underlying, ultimately...

type="main" xml:lang="en" <p>In this paper we examine the implications of two theories of informational frictions, signal extraction (SE) and rational inattention (RI), for optimal decisions and economic dynamics within the linear-quadratic-Gaussian (LQG) setting. We first show that if the variance...</p>

We examine the effects of two types of informational frictions, robustness (RB) and nite information-processing capacity (called rational inattention or RI) on the current account, in an otherwise standard intertemporal current account (ICA) model. We show that the interaction of RB and RI has...

In this paper we examine the effects of two types of information imperfections, robustness (RB) and nite information-processing capacity (called rational inattention or RI), on international consumption correlations in an otherwise standard small open economy model. We show that in the presence...

In this paper we examine how model uncertainty due to the preference for robustness (RB) affects optimal taxation and debt structure in the Barro tax-smoothing model (1979). We first study how the government spending shocks are absorbed in the short run by varying taxes or through debt under RB....
