Sources of Entropy in Representative Agent Models
Backus, David K. - 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 …

Evidence of Decreasing Internet Entropy : The Lack of Redundancy in Dns Resolution by Major Websites and Services
Bates, Samantha - 2018
This paper analyzes the extent to which the Internet's global domain name resolution (DNS) system has preserved its distributed resilience given the rise of cloud-based hosting and infrastructure. We explore trends in the concentration of the DNS space since at least 2011. In addition, we...

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...

Forecasts in a Slightly Misspecified Finite Order VAR
Müller, Ulrich K. - 2011
We propose a Bayesian procedure for exploiting small, possibly long-lag linear predictability in the innovations of a finite order autoregression. We model the innovations as having a log-spectral density that is a continuous mean-zero Gaussian process of order 1/√T. This local embedding makes...

Macroeconomics and Volatility : Data, Models, and Estimation
Fernández-Villaverde, Jesús - 2010
One basic feature of aggregate data is the presence of time-varying variance in real and nominal variables. Periods of high volatility are followed by periods of low volatility. For instance, the turbulent 1970s were followed by the much more tranquil times of the great moderation from 1984 to...

Hostility in Takeovers : in the Eyes of the Beholder?
Schwert, G. William - 2011
This paper examines whether hostile takeovers can be distinguished from friendly takeovers, empirically, based on accounting and stock performance data. Much has been made of this distinction in both the popular and the academic literature, where gains from hostile takeovers are typically...

Medium Term Business Cycles
Comin, Diego A. - 2011
Over the postwar, the U.S., Europe and Japan have experienced what may be thought of as medium frequency oscillations between persistent periods of robust growth and persistent periods of relative stagnation. These medium frequency movements, further, appear to bear some relation to the high...
