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 …

Term Structures of Asset Prices and Returns

Backus, David - 2016

We explore the term structures of claims to a variety of cash flows, namely, U.S. government bonds (claims to dollars), foreign government bonds (claims to foreign currency), inflation-adjusted bonds (claims to the price index), and equity (claims to future equity indexes or dividends). The...

Tempered Particle Filtering

Herbst, Edward P. - 2017

The accuracy of particle filters for nonlinear state-space models crucially depends on the proposal distribution that mutates time t-1 particle values into time t values. In the widely-used bootstrap particle filter, this distribution is generated by the state-transition equation. While...

Missing Events in Event Studies : Identifying the Effects of Partially-Measured News Surprises

Gürkaynak, Refet S. - 2018

Macroeconomic news announcements are elaborate and multi-dimensional. We consider a framework in which jumps in asset prices around macroeconomic news and monetary policy announcements reflect both the response to observed surprises in headline numbers and latent factors, reflecting other...

Indicator Variables for Optimal Policy Under Asymmetric Information

Svensson, Lars E. O.; Woodford, Michael - 2021

The optimal weights on indicators in models with partial information about the state of the economy and forward-looking variables are derived and interpreted, both for equilibria under discretion and under commitment. The private sector is assumed to have information about the state of the...

Indicator Variables for Optimal Policy

Svensson, Lars E. O.; Woodford, Michael - 2021

The optimal weights on indicators in models with partial information about the state of the economy and forward-looking variables are derived and interpreted, both for equilibria under discretion and under commitment. An example of optimal monetary policy with a partially observable potential...

Spurious Trend and Cycle in the State Space Decomposition of a Time Series with a Unit Root

Nelson, Charles R. - 2021

Recent research has proposed the state space (88) framework for decomposition of GNP and other economic time series into trend and cycle components, using the Kalman filter. This paper reviews the empirical evidence and suggests that the resulting decomposition may be spurious, just as...

Tests of Hypotheses Arising in the Correlated Random Coefficient Model

Heckman, James J. - 2010

This paper examines the correlated random coefficient model. It extends the analysis of Swamy (1971, 1974), who pioneered the uncorrelated random coefficient model in economics. We develop the properties of the correlated random coefficient model and derive a new representation of the variance...
