Angeletos, Marios - 2010

This paper studies policy in a class of economies in which information about commonly-relevant fundamentals -- such as aggregate productivity and demand conditions -- is dispersed and can not be centralized by the government. In these economies, the decentralized use of information can fail to...

Trading Costs and Informational Efficiency

Dávila, Eduardo - 2019

We study the effect of trading costs on information aggregation and acquisition in financial markets. For a given precision of investors' private information, an irrelevance result emerges when investors are ex-ante identical: price informativeness is independent of the level of trading costs....

Optimal Monetary Policy with Informational Frictions

Angeletos, George-Marios - 2011

This paper studies optimal policy in a business-cycle setting in which firms have a blurry understanding of the state of the economy due to informational or cognitive constraints. The latter are not only the source of nominal rigidity but also an impediment in the coordination of production. The...

Instrument-Based vs. Target-Based Rules

Halac, Marina - 2018

We develop a simple model to study rules based on instruments vs. targets. A principal faces a better informed but biased agent and relies on joint punishments as incentives. Instrument-based rules condition incentives on the agent's observable action; target-based rules condition incentives on...

Rationally Inattentive Behavior : Characterizing and Generalizing Shannon Entropy

Caplin, Andrew - 2017

We provide a full behavioral characterization of the standard Shannon model of rational inattention. The key axiom is "Invariance under Compression", which identifies this model as capturing an ideal form of attention-constrained choice. We introduce tractable generalizations that allow for many...

Sources of Entropy in Representative Agent Models

Backus, David - 2011

preferences, habits, and jumps. The metrics describe the pricing kernel's dispersion (the entropy of the title) and dynamics (time … dependence, a measure of how entropy varies over different time horizons). We show how each model generates entropy and time … approximations -- clarifies the mechanisms underlying these models. It also reveals, in some cases, tension between entropy, which …

Information Costs and Sequential Information Sampling

Hébert, Benjamin - 2018

We propose a new approach to modeling the cost of information structures in rational inattention problems, the "neighborhood-based" cost functions. These cost functions have two properties that we view as desirable: they summarize the results of a sequential evidence accumulation problem, and...
