According to Schumpeter (1934), entrepreneurs are driven to innovate not for the fruits of success but for success itself. This description of entrepreneurship echoes Weber’s (1958 ) description of the “spirit of capitalism,” which states that people enjoy the accumulation of wealth...

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...

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 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 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...

We use a recursive utility version of a basic Huggett (1993) model to study the cross-sectional dispersion of consumption and wealth (relative to income). The basic model implies too little dispersion compared to the data, whereas a one-parameter extension to include rational inattention...

This paper develops a tractable continuous-time recursive utility (RU) version of the Huggett (1993) model to explore how the preference for robustness (RB) interacts with intertemporal substitution and risk aversion and then affects the interest rate, the dynamics of consumption and income, and...
