Book Description
In an exchange economy in which there is a complete set of markets for macroeconomic risks but no market for idiosyncratic risks, we consider how the efficient risk-sharing rules for the macroeconomic risk are affected by the heterogeneity in the consumers' risk attitudes and idiosyncratic risks. We provide sufficient conditions under which an idiosyncratic risk increases cautiousness (the derivative of the reciprocal of the absolute risk aversion), the determinant of the curvatures of the efficient risk-sharing rules. While the curvature of the risk-sharing rules at high consumption levels are governed by the consumers' risk attitudes, the curvature at low consumption levels depend not only on the risk attitudes but also on the lower tail distributions of the idiosyncratic risks.

Book Description
The book provides an integrated approach to risk sharing, risk spreading and efficient regulation through principal agent models. It emphasizes the role of information asymmetry and risk sharing in contracts as an alternative to transaction cost considerations. It examines how contracting, as an institutional mechanism to conduct transactions, spreads risks while attempting consolidation. It further highlights the shifting emphasis in contracts from Coasian transaction cost saving to risk sharing and shows how it creates difficulties associated with risk spreading, and emphasizes the need for efficient regulation of contracts at various levels. Each of the chapters is structured using a principal agent model, and all chapters incorporate adverse selection (and exogenous randomness) as a result of information asymmetry, as well as moral hazard (and endogenous randomness) due to the self-interest-seeking behavior on the part of the participants.

Book Description
This paper examines qualitative properties of efficient insurance contracts in the presence of background risk. In order to get results for all strictly risk-averse expected utility maximizers, the concept of "stochastic increasingness" is used. Different assumptions on the stochastic dependence between the insurable and uninsurable risk lead to different qualitative properties of the efficient contracts. The new results obtained under hypotheses of dependent risks are compared to classical results in the absence of background risk or to the case of independent risks. The theory is further generalized to nonexpected utility maximizers.

Book Description
Sourcing Strategy is about sourcing as a long term strategic activity. Myopic purchasing management stops short with describing functional procedures and procedural innovations such as online order processing. The goal of this book is not merely to document sourcing strategy, but to provide the tools to determine it. Therefore, rather than merely describe common sourcing processes, the book takes a normative approach to sourcing strategy. It argues for a rational, complete and integrated process view. It supports its recommendations with logical arguments from an interdisciplinary and analytical approach grounded in microeconomics, law and business strategy. Part 1 of the book explains the economic and business principles that underlie sourcing strategies. It derives policies that guide viable strategies to meet sourcing goals. Part 2 applies these to creative designs for standard sourcing scenarios.

Book Description
The United States is unique among economically advanced nations in its reliance on employers to provide health benefits voluntarily for workers and their families. Although it is well known that this system fails to reach millions of these individuals as well as others who have no connection to the work place, the system has other weaknesses. It also has many advantages. Because most proposals for health care reform assume some continued role for employers, this book makes an important contribution by describing the strength and limitations of the current system of employment-based health benefits. It provides the data and analysis needed to understand the historical, social, and economic dynamics that have shaped present-day arrangements and outlines what might be done to overcome some of the access, value, and equity problems associated with current employer, insurer, and government policies and practices. Health insurance terminology is often perplexing, and this volume defines essential concepts clearly and carefully. Using an array of primary sources, it provides a store of information on who is covered for what services at what costs, on how programs vary by employer size and industry, and on what governments doâ€"and do not doâ€"to oversee employment-based health programs. A case study adapted from real organizations' experiences illustrates some of the practical challenges in designing, managing, and revising benefit programs. The sometimes unintended and unwanted consequences of employer practices for workers and health care providers are explored. Understanding the concepts of risk, biased risk selection, and risk segmentation is fundamental to sound health care reform. This volume thoroughly examines these key concepts and how they complicate efforts to achieve efficiency and equity in health coverage and health care. With health care reform at the forefront of public attention, this volume will be important to policymakers and regulators, employee benefit managers and other executives, trade associations, and decisionmakers in the health insurance industry, as well as analysts, researchers, and students of health policy.

Book Description
Recognition of take-up and transaction cost challenges in individual microinsurance has led to a surge of interest in group microinsurance. Yet few studies have considered the effect of group insurance on the investment decisions of the insured. In the case of weather index insurance, this is an important omission. Analogous to group microcredit, group weather insurance may exacerbate two key challenges depending on the information environment: moral hazard and group pressure. Experimental results from a framed field experiment in Gujarat, India, confirm that group pressure leads to an 8 percent reduction in risk taking in contexts with perfect information and group insurance (relative to individual insurance). The effects of moral hazard are more limited, however. As higher risk taking is associated with higher average agricultural productivity—and thus, development—these findings put a premium on greater attention to group selection, the information environment, and the regulation of payout distribution.

Book Description
An understanding of risk and how to deal with it is an essential part of modern economics. Whether liability litigation for pharmaceutical firms or an individual's having insufficient wealth to retire, risk is something that can be recognized, quantified, analyzed, treated--and incorporated into our decision-making processes. This book represents a concise summary of basic multiperiod decision-making under risk. Its detailed coverage of a broad range of topics is ideally suited for use in advanced undergraduate and introductory graduate courses either as a self-contained text, or the introductory chapters combined with a selection of later chapters can represent core reading in courses on macroeconomics, insurance, portfolio choice, or asset pricing. The authors start with the fundamentals of risk measurement and risk aversion. They then apply these concepts to insurance decisions and portfolio choice in a one-period model. After examining these decisions in their one-period setting, they devote most of the book to a multiperiod context, which adds the long-term perspective most risk management analyses require. Each chapter concludes with a discussion of the relevant literature and a set of problems. The book presents a thoroughly accessible introduction to risk, bridging the gap between the traditionally separate economics and finance literatures.

Book Description
This overview of project finance for the oil and gas industry covers financial markets, sources and providers of finance, financial structures, and capital raising processes. About US$300 billion of project finance debt is raised annually across several capital intensive sectors—including oil and gas, energy, infrastructure, and mining—and the oil and gas industry represents around 30% of the global project finance market. With over 25 year’s project finance experience in international banking and industry, author Robert Clews explores project finance techniques and their effectiveness in the petroleum industry. He highlights the petroleum industry players, risks, economics, and commercial/legal arrangements. With petroleum industry projects representing amongst the largest industrial activities in the world, this book ties together concepts and tools through real examples and aims to ensure that project finance will continue to play a central role in bringing together investors and lenders to finance these ventures. Combines the theory and practice of raising long-term funding for capital intensive projects with insights about the appeal of project finance to the international oil and gas industry Includes case studies and examples covering projects in the Arctic, East Africa, Latin America, North America, and Australia Emphasizes the full downstream value chain of the industry instead of limiting itself to upstream and pipeline project financing Highlights petroleum industry players, risks, economics, and commercial and legal arrangements

Book Description
"This white paper focusses on the policy interventions made to help people manage risk, uncertainty and the losses from events whose impacts are channeled primarily through the labor market. The objectives of the white paper are: to scrutinize the relevance and effects of prevailing risk-sharing policies in low- and middle-income countries; take account of how global drivers of disruption shape and diversify how people work; in light of this diversity, propose alternative risk-sharing policies, or ways to augment and improve current policies to be more relevant and responsive to peoples' needs; and map a reasonable transition path from the current to an alternative policy approach that substantially extends protection to a greater portion of working people and their families. This white paper is a contribution to the broader, global discussion of the changing nature of work and how policy can shape its implications for the wellbeing of people. We use the term risk-sharing policies broadly in reference to the set of institutions, regulations and interventions that societies put in place to help households manage shocks to their livelihoods. These policies include formal rules and structures that regulate market interactions (worker protections and other labor market institutions) that help people pool risks (social assistance and social insurance), to save and insure affordably and effectively (mandatory and incentivized individual savings and other financial instruments) and to recover from losses in the wake of livelihood shocks ('active' reemployment measures). Effective risk-sharing policies are foundational to building equity, resilience and opportunity, the strategic objectives of the World Bank's Social Protection and Jobs Global Practice. Given failures of factor markets and the market for risk in particular the rationale for policy intervention to augment the options that people have to manage shocks to their livelihoods is well-understood and accepted. By helping to prevent vulnerable people from falling into poverty --and people in the poorest households from falling deeper into poverty-- effective risk-sharing interventions dramatically reduce poverty. Households and communities with access to effective risk-sharing instruments can better maintain and continue to invest in these vital assets, first and foremost, their human capital, and in doing so can reduce the likelihood that poverty and vulnerability will be transmitted from one generation to the next. Risk-sharing policies foster enterprise and development by ensuring that people can take appropriate risks required to grasp opportunities and secure their stake in a growing economy."--
