This book describes a new pattern discovery approach based on the combination among rules between Perceptually Important Points (PIPs) and the Symbolic Aggregate approximation (SAX) representation optimized by Genetic Algorithm (GA). The proposed approach was tested with real data from S&P500 index and all the results obtained outperform the Buy&Hold strategy. Three different case studies are presented by the authors.

This book comprises four chapters, each of which examines public debt from a specific economic perspective. Chapter 1 studies potential fiscal externalities of the public debt in the framework of a monetary union. Chapter 2 examines the theoretical literature concerning how and if public debt impairs economic growth and finds no univocal and straightforward answer. Chapter 3 discusses the economic impact of the SARS-CoV-2 virus and addresses the question of whether limits to public debt ought to be respected or disregarded in the face of huge unemployment, collapsing tax revenues, and generous public expenditure programs. Lastly, Chapter 4 analyzes the response of central banks in emerging inflation targeting countries with floating exchange rates to changes in public debt.

Learn from a master of quantitative finance the rules that made him a success. The UnRules presents the dynamic rules for success in the age of exponential information. Written by Igor Tulchinsky, the trader behind global hedge fund firm WorldQuant, this book is more than just another Big Data guide for financial wonks it's a prescriptive, inspirational book for everyone navigating the tidal waves of the information age. Data is everywhere, coming at us in a never-ceasing, ever-rising river that threatens to overwhelm us. Tulchinsky shows us, however, how natural patterns underlie that data patterns that may dictate life or death, success or failure. The marriage of man and machines has allowed scientists to explore increasingly complex worlds, to predict outcomes and eventualities. This book demonstrates how to exercise real intelligence by discerning the patterns that surround us every day and how to leverage this information into success in the workplace and beyond. Beneath this story is Tulchinsky's description of how advances in mathematics and science have shaped the use of data and automation to pry open complex systems like the financial markets. Tulchinsky describes how he built WorldQuant into a global trading colossus from scratch, amassing millions of 'alphas,' computer algorithms that describe market relationships, and seeking talent from around the world to contribute their own ideas for new alphas. A key part of The UnRules is Tulchinsky's personal story. As a child, he fled with his parents from the Soviet Union in the 1970s and landed in New York, mastering American life, computer science and quantitative finance on his way to founding WorldQuant. Along the way, he developed a series of personal rules guidelines to success anchored by a paradoxical central UnRule: None of these rules is infallible. Life is risk. * Establish only concrete, quantifiable goals. * Think big it's easier. * Take aggressive risks but manage your losses. If it's scary, run. * Obstacles are information. * Ideas are infinite. For anyone, anywhere trying to make sense of our times, The UnRules offers perspective, context and deeply insightful strategies for navigating the future.

In Speculative Communities, Aris Komporozos-Athanasiou examines the ways that speculation has moved beyond financial markets to shape fundamental aspects of our social and political lives. As ordinary people make exceptional decisions, such as the American election of a populist demagogue or the British vote to leave the European Union, they are moving from time-honored and -tested practices of governance, toward the speculative promise of a new, more uncertain future. This book shows how even our methods of building community have shifted to the speculative realm as social media platforms enable and amplify our volatile wagers. For Komporozos-Athanasiou, "to speculate" means increasingly "to connect," to endorse the unknown pre-emptively, and often daringly, as a means of social survival. Grappling with the question of how more uncertainty can lead to its full-throated embrace rather than dissent, Speculative Communities shows how finance has become the model for society writ large. As Komporozos-Athanasiou argues, virtual marketplaces, new social media, and dating apps bring finance's opaque infrastructures into the most intimate realms of our lives, leading to a new type of speculative imagination across economy, culture, and society.

Ziel des Buches ist es, die mathematischen Methoden und deren Anwendung, welche heutzutage typischerweise in der Finanzwelt und bei der Beschreibung von Kapitalmärkten zum Einsatz kommen, in einem Band zusammenzufassen. Der Text kann etwa als Grundlage einer zweisemestrigen Vorlesung in einem Bachelor- oder Master-Studiengang (Wirtschafts-)Mathematik dienen, und gibt den Studenten, die bereits eine einführende Vorlesung zu den Themen der klassischen Finanzmathematik absolviert haben, einen Überblick über die konkrete Anwendung weiterführender mathematischer Methoden in der Finanzwelt. Es ist weniger theorielastig als viele vergleichbare Bücher und richtet den Fokus mehr auf das "tatsächlich vermittelbare und für die Praxis relevante" Wissen.

This book concentrates on some leading questions in M&A research in last two decades and tries to find explanations concerning cultural issues. It focuses on pre-merger/acquisition issues mainly on negotiation, decision and intercultural due diligence. The core of this book is the pre-M&A stage in order to throw light on the cultural issues related to negotiation, decision making, and due diligence. Its primary purpose is a finer view of the impact of national, organisational and professional cultures in mergers and acquisitions. The general questions encountered in this book are related to nexus between culture and integration of the two companies, management's involvement in the cultural due diligence process, national, organisational and professional cultures' link to negotiation and decision-making process, negotiators' behavioral patterns, intentions, perceptions and attitudes identified and associated with M&A's success, managers' cultural specificity and their management practices. The aim of this book is to provide a deeper understanding of the cultural differences in negotiation and decision-making. This might help organisations provide better opportunities for cross border M&A across a wide cultural spectrum. With the increase of global mobility, cultural due diligence becomes more and more important. Multi-national corporations might garner a competitive advantage when they understand the importance of cultural due diligence. M&A professionals may benefit from a deeper understanding of cultural values that affect the perceptions of individuals during negotiation and decision-making by profession across cultures. Multinational companies that do not take into consideration or minimise the importance and the right content of cultural due diligence expose themselves to a higher risk of failure. The expectation of the author of this book is that the conclusions would help alert M&A scholars and practitioners of the need to thoroughly understand the cultural issues influencing the pre-M&A processes.

Management is a fragmented and interdisciplinary area of study, with a lot of academic branches. Willman argues this tree is narrower at its roots, and these roots lie primarily in social science. Key to the purpose of the book is to present management theory as applied social science. Developed out of a core management course at Master's level, this book introduces the field to students who may have little prior knowledge of management. Willman interprets 'management' broadly to embrace the sub-disciplines of strategy, finance, accounting, marketing, organisational behaviour and operations management. The text aims to show how they arose and how they relate, thus engaging the reader in a little history. The book is integrative, in that it seeks to find common concerns in disparate literatures. It is also critical in that it seeks to comparatively evaluate contributions to the management field both in terms of theoretical contribution and practical impact. It is intended to be accessible to a range of readers, presenting technical materials in an informal way. Finally, it is introductory in that it assumes no previous knowledge of the academic management field.

Levy processes are the natural continuous-time analogue of random walks and form a rich class of stochastic processes around which a robust mathematical theory exists. Their application appears in the theory of many areas of classical and modern stochastic processes including storage models, renewal processes, insurance risk models, optimal stopping problems, mathematical finance, continuous-state branching processes and positive self-similar Markov processes.

This textbook is based on a series of graduate courses concerning the theory and application of Levy processes from the perspective of their path fluctuations. Central to the presentation is the decomposition of paths in terms of excursions from the running maximum as well as an understanding of short- and long-term behaviour.

The book aims to be mathematically rigorous while still providing an intuitive feel for underlying principles. The results and applications often focus on the case of Levy processes with jumps in only one direction, for which recent theoretical advances have yielded a higher degree of mathematical tractability.

The second edition additionally addresses recent developments in the potential analysis of subordinators, Wiener-Hopf theory, the theory of scale functions and their application to ruin theory, as well as including an extensive overview of the classical and modern theory of positive self-similar Markov processes. Each chapter has a comprehensive set of exercises.

Understanding cost behavior is a fundamental element of cost accounting and the management of a firm. Deviating from the traditional assumption of symmetric cost behavior, numerous recent research studies show that costs are sticky, that is, they decrease less when sales fall than they increase when sales rise. Daniel Baumgarten comprehensively analyzes the cost stickiness phenomenon by discussing its development and all relevant findings presented in the research literature. Furthermore, he provides several suggestions for future research and discusses important implications of cost stickiness for fundamental analysis and analysts' forecasts by means of two comprehensive empirical analyses.

Among the symmetrical distributions with an infinite domain, the most popular alternative to the normal variant is the logistic distribution as well as the Laplace or the double exponential distribution, which was first introduced in 1774. Occasionally, the Cauchy distribution is also used. Surprisingly, the hyperbolic secant distribution has led a charmed life, although Manoukian and Nadeau had already stated in 1988 that "... the hyperbolic-secant distribution ... has not received sufficient attention in the published literature and may be useful for students and practitioners." During the last few years, however, several generalizations of the hyperbolic secant distribution have become popular in the context of financial return data because of its excellent fit. Nearly all of them are summarized within this Springer Brief.

Why did some firms weather the financial crisis and others not? This book builds on the author's interviews and access to internal documents from over a dozen major financial companies, investigates their workings, reveals what went wrong and discovers a remedy. A critical difference between successful and unsuccessful firms is a culture that encourages respectful challenge, what the book calls "constructive dialogue. " At successful firms top management engaged in constructive dialogue with the board, a strong management team, and the chief risk officer, among others, in making a decision; firms that failed often featured overbearing (or distracted) CEOs or unit heads, supine boards, incapable management, ineffective risk officers, and poor communications both across silos and up the hierarchy. They often lacked ability to manage the firm as an integrated organization. Companies need good management, and not only good risk management, to stay out of trouble. Successful companies operated with strong information systems and a culture of good communications that brought issues promptly to top management so the company could adjust its operations accordingly. Successful managers had discipline to ask simple questions and pursue answers until they understood the risk-reward tradeoffs in their activities. Regulators too made mistakes. They didn't feel empowered to rein in companies that - at least before the crisis - seemed so profitable. Instead of waiting for a company to take losses, the book recommends that they use "constructive dialogue " as a test of good management and that supervisors require evidence that major business decisions result from a robust process rather than merely the will of a powerful CEO or heads of revenue-producing units. Companies in turn should use their regulator as a potential source of useful feedback. The book concludes by looking at major firms in other industries and finds that its conclusions apply to these companies too.

Do we really know the critical phenomena that are linked to how enterprises function and the dynamics of their relationships with customers, suppliers and competitors? Are their decision-making processes founded upon a set of performance measurements that were accurately designed and systematically elaborated? The above questions are the focus of this book, as is the following premise: enterprises need a system to measure their critical performances so they can be managed effectively; metaphorically speaking, enterprises need a "management dashboard" to serve as a navigational aid. A dashboard to show - with as few distortions as possible - the pattern of key variables that characterizes the specific formula enterprises use to face their competitive and social environment.
