Book Description
Today's top financial-risk professionals have come to rely on ever-more sophisticated mathematics in their attempts to come to grips with financial risk. But this excessive reliance on quantitative precision is misleading--and it puts us all at risk. This is the case that Riccardo Rebonato makes in Plight of the Fortune Tellers--and coming from someone who is both an experienced market professional and an academic, this heresy is worth listening to. Rebonato forcefully argues that we must restore genuine decision making to our financial planning, and he shows us how to do it using probability, experimental psychology, and decision theory. This is the only way to effectively manage financial risk in a manner congruent with how human beings actually react to chance. Rebonato challenges us to rethink the standard wisdom about probability in financial-risk management. Risk managers have become obsessed with measuring risk and believe that these quantitative results by themselves can guide sound financial choices--but they can't. In this book, Rebonato offers a radical yet surprisingly commonsense solution, one that seeks to remind us that managing risk comes down to real people making decisions under uncertainty. Plight of the Fortune Tellers is not only a book for the decision makers of Wall Street, it's a must-read for anyone concerned about how today's financial markets are run. The stakes have never been higher--can you risk it?

Book Description
This paper shows how one of the most popular savings products in Europe -- life insurance financial products -- shares market risk across investor cohorts. Insurers smooth returns by varying reserves that offset fluctuations in asset returns. Reserves are passed on between successive investor cohorts, causing redistribution across cohorts. Using regulatory and survey data on the 1.4 trillion euro French market, we estimate this redistribution to be quantitatively large: 1.4% of savings value per year on average, or 0.8% of GDP. These findings challenge a large theoretical literature that assumes inter-cohort risk sharing is impossible. We develop and provide evidence for a model in which the elasticity of investor demand to predictable returns determines the amount of risk sharing that is possible. The evidence is consistent with low elasticity, sustaining inter-cohort risk sharing despite predictable returns. Demand elasticity is higher for investors with a larger investment amount, suggesting that low investor sophistication enables inter-cohort risk sharing.

Book Description
Standard theoretical models predict that domestic residents should diversify their portfolios into foreign assets much more than observed in practice. Whether this lack of diversification is important depends upon the potential gains from risk-sharing. General equilibrium models and consumption data tend to find that the costs are small, typically less than «% of permanent consumption. On the other hand, stock returns imply gains that are several hundred times larger. In this paper, I examine the reasons for these differences. I find that the primary differences are due to either: (a) the much higher variability of stocks, and/or (b) the higher degree of risk aversion required to reconcile an international equity premium. On the other hand, the significant differences do not arise treating stock returns as exogenous.

Book Description
Risk and Return for Regulated Industries provides a much-needed, comprehensive review of how cost of capital risk arises and can be measured, how the special risks regulated industries face affect fair return, and the challenges that regulated industries are likely to face in the future. Rather than following the trend of broad industry introductions or textbook style reviews of utility finance, it covers the topics of most interest to regulators, regulated companies, regulatory lawyers, and rate-of-return analysts in all countries. Accordingly, the book also includes case studies about various countries and discussions of the lessons international regulatory procedures can offer. Presents a unified treatment of the regulatory principles and practices used to assess the required return on capital Addresses current practices before exploring the ways methods play out in practice, including irregularities, shortcomings, and concerns for the future Focuses on developed economies instead of providing a comprehensive global reviews Foreword by Stewart C.

Book Description
International consumption risk sharing studies have largely ignored their models' counterfactual implications for asset returns although these returns incorporate direct market measures of risk. In this paper, we modify a canonical risk-sharing model to generate more plausible asset return behavior and then consider the effects on welfare gains. Matching the mean and variance of equity returns and the risk-free rate requires persistent consumption risk, leading to three main findings: (1) risk-sharing gains decrease as the ability to diversify persistent consumption risk decreases; (2) the international correlation of equity returns is high relative to the correlation of consumption and dividends, implying low diversification potential for persistent consumption risk; and (3) increasing persistent consumption risk reduces the gains. Taken together, our findings suggest that asset returns imply more international risk sharing than previously thought.

Book Description
The Nobel Prize-winning Father of Modern Portfolio Theory re-introduces his theories for the current world of investing Legendary economist Harry M. Markowitz provides the insight and methods you need to build a portfolio that generates strong returns for the long run In Risk-Return Analysis, Markowitz corrects common misunderstandings about Modern Portfolio Theory (MPT) to help advanced financial practitioners dramatically improve their decision making. In this first volume of a groundbreaking four-part series sure to draw the attention of anyone interested in MPT, Markowitz provides the criteria necessary for judging among risk-measures; surveys a half-century of literature (nearly all of which has been ignored by textbooks) on the applicability of MPT; and presents an empirical study of which functions of mean and some risk-measure is best for those who seek to maximize return in the long run. Harry M. Markowitz is a Nobel Laureate and the father of Modern Portfolio Theory.

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."--

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.
