Sectoral Uncertainty

SSRN Electronic Journal, 2022
Nous proposons un nouveau cadre empirique qui permet de décomposer simultanément la variance conditionnelle des séries chronologiques de données économiques en deux facteurs : l’incertitude agrégée et l’incertitude sectorielle. Nous appliquons notre cadre à un vaste ensemble de données désagrégées relatives à la production industrielle aux États-Unis ...

Uncertainties

Science and Engineering Ethics, 2009
In contemporary science uncertainty is often represented as an intrinsic feature of natural and of human phenomena. As an example we need only think of two important conceptual revolutions that occurred in physics and logic during the first half of the twentieth century: (1) the discovery of Heisenberg's uncertainty principle in quantum mechanics; (2 ...

Visualizing Uncertainty with Uncertainty Multiples

GeoCongress 2006, 2006
It is difficult to depict uncertainty graphically. Conventional means, which rely on mapping uncertainty to graphical attributes in an image, have limited effectiveness because they require presenting additional variables and are not generally intuitive. The concept of uncertainty multiples is proposed herein to address these challenges.

Sovereign Uncertainty

SSRN Electronic Journal, 2019

Employing a data‐rich approach, I introduce a novel proxy that captures uncertainty surrounding public finances, which I refer to as sovereign uncertainty.
