An easy-to-understand guide to modelling productivity and efficiency using modern statistical tools. Introduces the fundamentals of stochastic frontier analysis (SFA) and the latest concepts and methods related to the use of copulas in SFA. A useful reference for those interested in the newest robust methods of business analytics.

Web series are a modern and actively developing audiovisual format, which, however, has so far received only limited attention from researchers. The format's specific nature implies that it must be viewed from three angles at once: as an audiovisual product, in many ways akin to television and cinema formats; as a type of Internet content that exists in tune with the laws of its environment; and, finally, as a series per se, created with the canons and rules of serial narration in mind. Building on these three key aspects, it is possible to identify the specific format features of a web series and to find out how they influence its creation process, for example, in terms of storytelling strategies used in web series scriptwriting.This article examines nine web series of different genres, produced in nine countries around the world. The aim of the study is to discover and trace the relationship between the specific features of web series as a format and the story structure of the selected series. Joseph Campbell's monomyth scheme serves as a main tool of analysis and allows to present this structure as a series of key stages, making it explicit. As a result, it becomes visible how the hero's classic journey gets transformed in a web series. This makes it possible to identify the main features of storytelling in this format and the techniques used by screenwriters. These techniques include, in particular, a quick start of the story, a focus on the heroes' inner journey, complete exclusion of their parents from the plot, and some others. Thus, the study comes to the conclusion that the specificity of web series as a format is not only taken into account by screenwriters, but also forces them to transform the classic plot schemes to a large extent.

"This book offers a unified approach to the study of crises, large fluctuations, dependence and contagion effects in economics and finance. It covers important topics in statistical modeling and estimation, which combine the notions of copulas and heavy tails — two particularly valuable tools of today's research in economics, finance, econometrics and other fields — in order to provide a new way of thinking about such vital problems as diversification of risk and propagation of crises through financial markets due to contagion phenomena, among others. The aim is to arm today's economists with a toolbox suited for analyzing multivariate data with many outliers and with arbitrary dependence patterns. The methods and topics discussed and used in the book include, in particular, majorization theory, heavy-tailed distributions and copula functions — all applied to study robustness of economic, financial and statistical models, and estimation methods to heavy tails and dependence."--Publisher's website

AbstractWe estimate intergenerational income mobility in the US and Sweden, using a new nonparametric approach. The approach addresses several empirical issues raised in the literature and applies when other estimators are infeasible. We argue that previous estimates of income mobility conceal the heterogeneous nature of the transmission mechanism by keeping mobility constant across families. The striking differences we find between mobility patterns across family backgrounds, captured by father's education, lead us to question the conventional result that intergenerational transmission of earnings is weaker in Sweden than in the United States, for important parts of the population.
