Book Description
The author's particular interest in the area of risk measures is to combine this theory with the analysis of dependence properties. The present volume gives an introduction of basic concepts and methods in mathematical risk analysis, in particular of those parts of risk theory that are of special relevance to finance and insurance. Describing the influence of dependence in multivariate stochastic models on risk vectors is the main focus of the text that presents main ideas and methods as well as their relevance to practical applications. The first part introduces basic probabilistic tools and methods of distributional analysis, and describes their use to the modeling of dependence and to the derivation of risk bounds in these models. In the second, part risk measures with a particular focus on those in the financial and insurance context are presented. The final parts are then devoted to applications relevant to optimal risk allocation, optimal portfolio problems as well as to the optimization of insurance contracts. Good knowledge of basic probability and statistics as well as of basic general mathematics is a prerequisite for comfortably reading and working with the present volume, which is intended for graduate students, practitioners and researchers and can serve as a reference resource for the main concepts and techniques.

Book Description
The focus of this thesis is on consumer diversity. Incorporating consumer heterogeneity into economic analysis is well-established in industrial organization literature; this aspect is, however, often neglected in microeconomic insurance models. A first new approach lies in analyzing risk interdependencies. When risks are interdependent, an agent's decision to self-protect affects the loss probabilities faced by others. Due to these externalities, economic agents invest too little in prevention relative to the socially efficient level by ignoring marginal external costs or benefits conferred on others. We analyze an insurance market with externalities of loss prevention. It is shown in a model with heterogenous agents and imperfect information that a monopolistic insurer can achieve the social optimum by engaging in premium discrimination. An insurance monopoly reduces not only costs of risk selection, but may also play an important social role in loss prevention. This result can be empirically confirmed. We also deal with the impact of intermediation on insurance market transparency and performance. In a differentiated insurance market under imperfect information, uninformed consumers may become informed about product suitability by consulting an intermediary. We analyze current broker compensation systems: commissions and fees. While insurers' equilibrium profits are equivalent under both systems, social welfare under fees is first-best efficient. Both systems may offer the opportunity to increase profits via collusion. Under a commission system, collusion enables insurers to separate consumers into groups purchasing different contracts. Insurers may then extract additional rents from some consumers. This might explain why intermediaries tend to be compensated by insurers in practice. Finally, we study optimal monopoly pricing given imperfect information and heterogenous policyholders. Die in englischer Sprache verfasste Arbeit ist der mikroökonomischen Analyse von Versicherungsmärkten gewidmet. Zunächst werden einige wichtige theoretische Grundlagen der Versicherungsnachfragetheorie beschrieben. Eine zentrale Erweiterung des Basismodells stellen interdependente Risiken dar. Bestehen Risikointerdependenzen, so sind alle Maßnahmen, die die Schadenshäufigkeit reduzieren, mit positiven externen Effekten verbunden. Es wird gezeigt, dass im Gleichgewicht das realisierte Präventionsniveau unterhalb des optimalen Niveaus angesiedelt ist. Aufgrund der Externalitäten kommt es zu einem Marktversagen und nur ein Monopolversicherer kann eine differenzierte Prämienstruktur herbeiführen, die zum optimalen Präventionsniveau führt. Dieses Ergebnis kollidiert mit dem Ergebnis, dass wettbewerbliche Versicherungsmärkte zu einer höheren Gesamtwohlfahrt führen, es lässt sich jedoch empirisch stützen. Ein weiterer Schwerpunkt der Arbeit liegt auf unvollkommenen Versicherungsmärkten, wobei heterogene Versicherungsnachfrager mit unterschiedlichen Produktpräferenzen und Informationskosten unterstellt werden. In einem solchen Markt erhöhen Versicherungsvermittler die Markttransparenz und damit auch die Gewinne der Versicherer. Im Mittelpunkt steht die Analyse verschiedener Vergütungsformen der Vermittler. Ein Vergütungssystem auf Basis von Beratungshonoraren ist einem Provisionssystem aus wohlfahrtsökonomischer Perspektive vorzuziehen. Aus Sicht der Versicherer kehrt sich dieses Ergebnis allerdings um, sobald es zur Kollusion zwischen Versicherern und Vermittlern kommt. Der letzte Schwerpunkt liegt in der Analyse einer optimalen Preispolitik eines Versicherungsmonopolisten bei heterogenen Nachfragern, die sich durch ihre Risikopräferenzen und damit ihre individuelle Zahlungsbereitschaft für Versicherungen unterscheiden.

Book Description
The concept of risk-sharing in financial and social contracts is one of the unique features of Islamic finance. Many theoretical studies generally claim superiority of an Islamic financial system based on pure equity and participatory modes of financing, while empirical studies provide mixed results. Studies and discussions are needed to fully understand how Islamic finance could contribute to the ongoing discussion of financial stability. Against this background, this book addresses various aspects of Islamic finance and the risk-sharing mechanism contributions to the overall macroeconomic and financial stability. Undoubtedly, the findings and recommendation from this book should be of great interest not only to future academic researchers in the field of macroeconomic stability and Islamic finance, but also to policy makers and regulators who are keen on drawing lessons from Islamic finance experiences to prevent similar crisis in the future.

Book Description
An introduction to the use of probability models for analyzing risk and economic decisions, using spreadsheets to represent and simulate uncertainty. This textbook offers an introduction to the use of probability models for analyzing risks and economic decisions. It takes a learn-by-doing approach, teaching the student to use spreadsheets to represent and simulate uncertainty and to analyze the effect of such uncertainty on an economic decision. Students in applied business and economics can more easily grasp difficult analytical methods with Excel spreadsheets. The book covers the basic ideas of probability, how to simulate random variables, and how to compute conditional probabilities via Monte Carlo simulation. The first four chapters use a large collection of probability distributions to simulate a range of problems involving worker efficiency, market entry, oil exploration, repeated investment, and subjective belief elicitation. The book then covers correlation and multivariate normal random variables; conditional expectation; optimization of decision variables, with discussions of the strategic value of information, decision trees, game theory, and adverse selection; risk sharing and finance; dynamic models of growth; dynamic models of arrivals; and model risk. New material in this second edition includes two new chapters on additional dynamic models and model risk; new sections in every chapter; many new end-of-chapter exercises; and coverage of such topics as simulation model workflow, models of probabilistic electoral forecasting, and real options. The book comes equipped with Simtools, an open-source, free software used througout the book, which allows students to conduct Monte Carlo simulations seamlessly in Excel.

Book Description
Nonfinancial Defined Contribution (NDC) schemes are now in their teens. The new pension concept was born in the early 1990s, implemented from the mid-1990s in Italy, Latvia, Poland and Sweden, legislated most recently in Norway and Egypt and serves as inspiration for other reform countries. This innovative unfunded individual account scheme created high hopes at a time when the world seemed to have been locked into a stalemate between piecemeal reforms of ailing traditional defined benefit schemes and introducing pre-funded financial account schemes. The experiences and conceptual issues of NDC in its childhood were reviewed in a prior anthology (Holzmann and Palmer, 2006). This new anthology published in 2 volumes serves to review its adolescence and with the aim of contributing to a successful adulthood. Volume 1 on Progress, Lessons, Implementation includes a detailed analysis of the experience and the key policy lessons in the old and new pilot countries and the implementation of NDCs elements in other reform countries. This volume 2 on Gender, Politics, Financial Stability includes deeper and new analyses of these issues that found little or no attention in the 2006 publication. The gender perspective includes 5 chapters with, perhaps, the most complete discussion on gender and pension issues available to date. The financial stability perspective addresses in 6 chapters critical micro- and macroeconomic aspects such as the balancing mechanism, the use of a reserve fund, the handling of legacy costs, and technicalities related to the management of the longevity risk when designing annuities. While the 2 volumes address many issues it also opens a number of new questions for which good answers are not yet readily available.

Book Description
The book offers an introduction to the technical foundation of decentralized insurance models, for advanced undergraduate students, graduate students and practitioners. The book is self-contained and anyone with a basic knowledge of probability and statistics should be able to follow through the entire book. It adopts a minimalist approach to describe the essential elements and first principles so that readers can get a gist of these models without being overwhelmed with too much technicality. It can be used as a reference for business model designs. The inclusion of exercises and practical examples makes the book suitable for advanced courses on decentralized insurance and risk sharing. There is a mix of industry practices and academic models presented in this book. The exposition starts with an overview of historic and current business practices and preliminaries on the mathematics and economics of risk and insurance. A bird's-eye view of traditional insurance is provided as a benchmark for various topics to be used in contrast with decentralized insurance. The book then continues with decentralized insurance practices around the world, including online mutual aid originated in China, takaful from the Islamic world, peer-to-peer insurance in the West, catastrophe risk pooling for Carribean countries, etc. Theories of aggregate risk pooling and peer-to-peer risk exchanges are provided for readers to appreciate the mathematical foundation of risk sharing. A unified framework of decentralized insurance is presented to show a structured approach to the economic design of decentralized business models. The book ends with a technical review of blockchain and decentralized finance (DeFi) insurance applications.

Book Description
Gain a holistic view of agricultural (re)insurance and capital market risk transfer Increasing agricultural production and food security remain key challenges for mankind. In order to meet global food demand, the Food and Agriculture Organisation estimates that production has to increase by 50% by 2050 and requires large investments. Agricultural insurance and financial instruments have been an integral part to advancing productivity and are becoming more important in increasingly globalized and specialized agricultural supply chains in the wake of potentially more frequent and severe natural disasters in today’s key producing markets. Underwriting, pricing and transferring agricultural risks is complex and requires a solid understanding of the production system, exposure, perils and the most suitable products, which vastly differ among developed and developing markets. In the last decade, new insurance schemes in emerging agricultural markets have greatly contributed to the large growth of the industry from a premium volume of US$10.1 billion (2006) to US$30.7 billion (2017). This growth is bound to continue as insurance penetration and exposure increase and new schemes are being developed. Agricultural (re)insurance has become a cornerstone of sovereign disaster risk financing frameworks. Agricultural Risk Transfer introduces the main concepts of agricultural (re)insurance and capital market risk transfer that are discussed through industry case studies. It also discusses best industry practices for all main insurance products for crop, livestock, aquaculture and forestry risks including risk assessment, underwriting, pricing, modelling and loss adjustment. Describes agricultural production risks and risk management approaches Covers risk transfer of production and financial risks through insurance and financial instruments Introduces modelling concepts for the main perils and key data sources that support risk transfer through indemnity- and index-based products Describes risk pricing and underwriting approaches for crop, livestock, aquaculture and forestry exposure in developed and developing agricultural systems Become familiar with risk transfer concepts to reinsurance and capital markets Get to know the current market landscape and main risk transfer products for individual producers, agribusinesses and governments through theory and comprehensive industry case studies Through Agricultural Risk Transfer, you’ll gain a holistic view of agricultural (re)insurance and capital market solutions which will support better underwriting, more structured product development and improved risk transfer.
