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...

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...

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 …We propose two metrics for asset pricing models and apply them to representative agent models with recursive … dependence, a measure of how entropy varies over different time horizons). We show how each model generates entropy and time …

Evolving Standards for Academic Publishing : A q-r Theory
Ellison, Glenn - 2000
This paper develops a model of evolving standards for academic publishing. It is motivated by the increasing tendency of academic journals to require multiple revisions of articles and by changes in the content of articles. Papers are modeled as varying along two quality dimensions: q and r. The...

Controlling Stocks and Flows to Promote Quality : The Environment, With Applications to Physical and Human Capital
Keohane, Nathaniel O. - 2000
Our analysis melds two traditional approaches to promoting quality. The first is restoring the stock of quality. The second is curbing its flow of deterioration. Although both approaches are widely used in real world settings, analytic models have tended to focus on one strategy or the other. We...

Quantifying Quality Growth
Bils, Mark - 2000
We introduce an instrumental variables approach to estimate the importance of unmeasured quality growth for a set of 66 durable consumer goods. Our instrument is based on predicting which of these 66 goods will display rapid quality growth. Using pooled cross- relatively sections of households...

If at First You Don't Succeed... : Profits, Prices and Market Structure in a Model of Quality with Unknowable Consumer Heterogeneity
Krishna, Kala - 2000
Why are higher quality niches seen as intrinsically more profitable in business circles? Why do high quality products sometimes have a low real price, while it is unusual to see low quality products with high real prices? Can markets have quality differentiation as well as quality bunching? In...

Does School Quality Matter? Returns to Education and the Characteristics of Schools in South Africa
Case, Anne - 1999
This paper contributes to what is known about the impact of school quality, by documenting its effect on the incomes of Black South Africans, using data from the 1996 South African census and two national surveys of school quality. South Africa provides an interesting laboratory for studying the...
