Book Description
During the last two decades actuarial research has developed in a more applied direction. Although the original risk models generally served as convenient and sometimes tractable mathematical examples of general probabilistic and/or statistical theories, nowadays models and techniques are encountered that can be considered to be typically actuarial. Examples include ordering of risks by dangerousness, credibility theory and techniques based on IBNR models. Not only does this book present the underlying mathematics of these subjects, but it also deals with the practical application of the techniques. In order to provide results based on real insurance portfolios, use is made of three software packages, namely SLIC performing stop-loss insurance calculations for individual and collective risk models, CRAC dealing with actuarial applications of credibility theory, and LORE giving IBNR-based estimates for loss reserves. Worked-out examples illustrate the theoretical results. This book is intended for use in preparing university actuarial exams, and contains many exercises with varying levels of complexity. It is valuable as a textbook for students in actuarial sciences during their last year of study. Due to the emphasis on applications and because of the worked-out examples on real portfolio data, it is also useful for practising actuaries to guide them in interpreting their own results.

bookdown: Authoring Books and Technical Documents with R Markdown presents a much easier way to write books and technical publications than traditional tools such as LaTeX and Word. The bookdown package inherits the simplicity of syntax and flexibility for data analysis from R Markdown, and extends R Markdown for technical writing, so that you can make better use of document elements such as figures, tables, equations, theorems, citations, and references. Similar to LaTeX, you can number and cross-reference these elements with bookdown. Your document can even include live examples so readers can interact with them while reading the book. The book can be rendered to multiple output formats, including LaTeX/PDF, HTML, EPUB, and Word, thus making it easy to put your documents online. The style and theme of these output formats can be customized. We used books and R primarily for examples in this book, but bookdown is not only for books or R. Most features introduced in this book also apply to other types of publications: journal papers, reports, dissertations, course handouts, study notes, and even novels. You do not have to use R, either. Other choices of computing languages include Python, C, C++, SQL, Bash, Stan, JavaScript, and so on, although R is best supported. You can also leave out computing, for example, to write a fiction. This book itself is an example of publishing with bookdown and R Markdown, and its source is fully available on GitHub.

Book Description
This contributed volume focuses on diasporans, their characteristics, networks, resources and activities in relation to international business and entrepreneurship. It presents an overview of diaspora concepts from an economic perspective, and analyzes the global-economic and societal effects and mechanisms, revealing both positive and negative aspects of diaspora activities. Providing insights into the socio-cultural influences, it discusses diaspora entrepreneurship and international business, the respective organisational models, investments and business types. Lastly it offers an assessment of managing diaspora resources and policymaking. This book was created by an interdisciplinary team of editors, co-authors and reviewers including historians, sociologists, psychologists, linguists and ethnologists, as well as experts in public policy, international business, marketing and entrepreneurship. This unique team (many of the authors are themselves diasporans with an extensive understanding of their topic) provides the first global academic platform on the subject, combining the latest empirical evidence from developing, emerging, transitional and developed countries with various combinations of diaspora flows that to date have received little attention.

Book Description
The increasing complexity of insurance and reinsurance products has seen a growing interest amongst actuaries in the modelling of dependent risks. For efficient risk management, actuaries need to be able to answer fundamental questions such as: Is the correlation structure dangerous? And, if yes, to what extent? Therefore tools to quantify, compare, and model the strength of dependence between different risks are vital. Combining coverage of stochastic order and risk measure theories with the basics of risk management and stochastic dependence, this book provides an essential guide to managing modern financial risk. * Describes how to model risks in incomplete markets, emphasising insurance risks. * Explains how to measure and compare the danger of risks, model their interactions, and measure the strength of their association. * Examines the type of dependence induced by GLM-based credibility models, the bounds on functions of dependent risks, and probabilistic distances between actuarial models. * Detailed presentation of risk measures, stochastic orderings, copula models, dependence concepts and dependence orderings. * Includes numerous exercises allowing a cementing of the concepts by all levels of readers. * Solutions to tasks as well as further examples and exercises can be found on a supporting website. An invaluable reference for both academics and practitioners alike, Actuarial Theory for Dependent Risks will appeal to all those eager to master the up-to-date modelling tools for dependent risks. The inclusion of exercises and practical examples makes the book suitable for advanced courses on risk management in incomplete markets. Traders looking for practical advice on insurance markets will also find much of interest.

Book Description
Chinese Insurance Contracts: Law and Practice is the first systematic text written in English on the law of insurance in China. This book offers a critical analysis of the major principles, doctrines and concepts of insurance contract law in China. At every point the analysis discusses the principles of the Insurance Law in detail, referring where appropriate to decided cases and also drawing attention to external influences. Readers are guided through the complexities of Chinese law in a clear and comprehensive fashion, and – significantly – in a manner that is accessible and meaningful for those used to a common law system. This book presents a comprehensive picture of Chinese insurance contract law, to facilitate a wider understanding of the relevant rules of law. Elements of insurance contract law are critically examined. In addition, this book presents rules of law on some special types of insurance contract, such as life insurance, property insurance, liability insurance, motor vehicle insurance, reinsurance, and marine insurance. The deficiencies and shortcomings of the law and practice will be identified and analysed; suggestions and recommendations on how to reform the law will be presented. Chinese Insurance Contracts also offers legal and practical advice to insurance professionals on how to draft clauses to avoid contractual pitfalls. It also uses cases to illustrate the difficulties which can arise in applying the principles in practice. This book will be essential reading for insurance companies and legal practitioners looking to do business in China, as well as reference for Chinese lawyers practising insurance law. It will also be a useful resource for students and academics studying Chinese law.

Book Description
The book provides a comprehensive overview of the latest econometric methods for studying the dynamics of macroeconomic and financial time series. It examines alternative methodological approaches and concepts, including quantile spectra and co-spectra, and explores topics such as non-linear and non-stationary behavior, stochastic volatility models, and the econometrics of commodity markets and globalization. Furthermore, it demonstrates the application of recent techniques in various fields: in the frequency domain, in the analysis of persistent dynamics, in the estimation of state space models and new classes of volatility models. The book is divided into two parts: The first part applies econometrics to the field of macroeconomics, discussing trend/cycle decomposition, growth analysis, monetary policy and international trade. The second part applies econometrics to a wide range of topics in financial economics, including price dynamics in equity, commodity and foreign exchange markets and portfolio analysis. The book is essential reading for scholars, students, and practitioners in government and financial institutions interested in applying recent econometric time series methods to financial and economic data.

Book Description
Considerable evidence suggests that many people for whom insurance is worth purchasing do not have coverage and others who appear not to need financial protection against certain events actually have purchased coverage. There are certain types of events for which one might expect to see insurance widely marketed are now viewed today by insurers as uninsurable and there are other policies one might not expect to be successfully marketed that exist on a relatively large scale. In addition, evidence suggests that cost-effective preventive measures are sometimes rewarded by insurers in ways that could change their clients' behavior. These examples reveal that insurance purchasing and marketing activities do not always produce results that are in the best interest of individuals at risk. Insurance Decision Making and Market Behavior discusses such behavior with the intent of categorizing these insurance "anomalies". It represents a first step in constructing a theory of insurance decision making to explain behavior that does not conform to standard economic models of choice and decision-making. Finally, the authors propose a set of prescriptive solutions for improving insurance decision-making.
