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...

The Equity Premium and Structural Breaks
Pastor, Lubos - 2000
A long return history is useful in estimating the current equity premium even if the historical distribution has experienced structural breaks. The long series helps not only if the timing of breaks is uncertain but also if one believes that large shifts in the premium are unlikely or that the...

Exchange Rate Returns Standardized by Realized Volatility are (Nearly) Gaussian
Andersen, Torben G. - 2000
It is well known that high-frequency asset returns are fat-tailed relative to the Gaussian distribution tails are typically reduced but not eliminated when returns are standardized by volatilities estimated from popular models such as GARCH. We consider two major dollar exchange rates, and we...

A Heuristic Method for Extracting Smooth Trends from Economic Time Series
Rotemberg, Julio J. - 1999
This paper proposes a method for separating economic time series into a smooth component whose mean varies over time (the trend') and a stationary component (the cycle'). The aim is to make the trends as smooth as possible while also producing cycles with plausible properties. While the main...

The Band Pass Filter
Christiano, Lawrence J. - 1999
The `ideal' band pass filter can be used to isolate the component of a time series that lies within a particular band of frequencies. However, applying this filter requires a dataset of infinite length. In practice, some sort of approximation is needed. Using projections, we derive...

Hostility in Takeovers : In the Eyes of the Beholder?
Schwert, G. William - 1999
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...
