A new, more accurate take on the classical approach to volatility evaluation Inside Volatility Filtering presents a new approach to volatility estimation, using financial econometrics based on a more accurate estimation of the hidden state. Based on the idea of "filtering", this book lays out a two-step framework involving a Chapman-Kolmogorov prior distribution followed by Bayesian posterior distribution to develop a robust estimation based on all available information. This new second edition includes guidance toward basing estimations on historic option prices instead of stocks, as well as Wiener Chaos Expansions and other spectral approaches. The author's statistical trading strategy has been expanded with more in-depth discussion, and the companion website offers new topical insight, additional models, and extra charts that delve into the profitability of applied model calibration. You'll find a more precise approach to the classical time series and financial econometrics evaluation, with expert advice on turning data into profit. Financial markets do not always behave according to a normal bell curve. Skewness creates uncertainty and surprises, and tarnishes trading performance, but it's not going away. This book shows traders how to work with skewness: how to predict it, estimate its impact, and determine whether the data is presenting a warning to stay away or an opportunity for profit. * Base volatility estimations on more accurate data * Integrate past observation with Bayesian probability * Exploit posterior distribution of the hidden state for optimal estimation * Boost trade profitability by utilizing "skewness" opportunities Wall Street is constantly searching for volatility assessment methods that will make their models more accurate, but precise handling of skewness is the key to true accuracy. Inside Volatility Filtering shows you a better way to approach non-normal distributions for more accurate volatility estimation.

Increased competition among firms and the threat of manufacturers in low-cost countries (LCCs) has forced many companies to pursue sourcing in LCCs. Low-cost country sourcing can cut expenses substantially, and as many companies consider themselves forced to choose this strategy, others regard it as an opportunity, sourcing high-tech products or even moving their R&D activities to these countries. However, sourcing in low-cost countries is a difficult task and firms need to conduct a thorough feasibility study before entering a market. By studying 4 international companies; (IKEA, Ericsson, Electrolux and Powerwave), this book investigates 3 basic questions that companies on the verge of starting their LCC sourcing activities would want to know. This work investigates what the types of products that are most suitable to source from low-cost countries, what type of contractual business forms which are more suitable when establishing production or sourcing activities in LCCs, and how companies' organization structure is affected by their low-cost sourcing strategy.

Les methodes couramment utilisees pour estimer la valeur d'un produit alimentaire pour les consommateurs reposent sur l'hypothese de la rationalite de la theorie economique classique. Elle suppose que les individus ont des preferences qui satisfont des axiomes tels que l'ordre, la completude, la reflexivite et la transitivite, qui impliquent l'existence d'une fonction d'utilite bien definie. Pourtant, depuis le milieu du 20eme siecle les psychologues et les economistes, en utilisant des experiences en laboratoire, ont trouve des evidences d'une deviation systematique des comportements par rapport aux predictions de la theorie (ex: inversion des preferences). Si les mesures des preferences des consommateurs sont basees sur des choix irrationnels ou incoherents, la question de fiabilite de ces methodes devrait etre posee. L'objectif de ce document est double: premierement, il analyse les paradoxes de choix dans le cas des produits alimentaires, en se basant sur des resultats experimentaux, et deuxiemement, il propose des methodes pour etudier l'effet de l'information sur les prix de reserve des produits alimentaires.
