-consistent expectations. This implicitly assumes unrealistic cognitive abilities on the part of economic decision makers. The relevant … question, however, is not whether the assumption can be literally correct, but how much it would matter to model decision … problems such as chess or go, in which decision makers look ahead only a finite distance into the future, and use a value …

This paper defines and analyzes a "sparse max" operator, which is a less than fully attentive and rational version of the traditional max operator. The agent builds (as economists do) a simplified model of the world which is sparse, considering only the variables of first-order importance. His...

We assume that the instantaneous riskless rate reverts towards a central tendency which in turn, is changing stochastically over time. As a result, current short-term rates are notquot; sufficient to predict future short-term rates movements, as would be the case if the centralquot; tendency was...

This paper extends the benchmark New-Keynesian model by introducing two frictions: (1) agent heterogeneity with incomplete markets, uninsurable idiosyncratic risk, and occasionally binding borrowing constraints; and (2) bounded rationality in the form of level-k thinking. Compared to the...

Motivated by recent developments in the bounded rationality and strategic complementarity literatures, we examine an intentionally simple and stylized aggregative economic model, when the assumptions of fully rational expectations and no strategic interactions are relaxed. We show that small...

Does bounded rationality make paternalism more attractive? This Essay argues that errors will be larger when suppliers have stronger incentives or lower costs of persuasion and when consumers have weaker incentives to learn the truth. These comparative statics suggest that bounded rationality...

The model of rational inattention with Shannon mutual information costs is increasingly ubiquitous. We introduce a new solution method that lays bare the general behavioral properties of this model and liberates development of alternative models. We experimentally test a key behavioral property...

This paper presents a framework for analyzing how bounded rationality affects monetary and fiscal policy. The model is a tractable and parsimonious enrichment of the widely-used New Keynesian model – with one main new “cognitive discounting” parameter, which quantifies how poorly agents...
