Book Description
Economic analysis of choice under uncertainty has been dominated by the expected utility (EU) model, yet the EU model has never been without critics. Psychologists accumulated evidence that individual choices under uncertainty were inconsistent with the predictions of the EU model. Applied work in areas such as finance was dominated by the simpler mean-variance analysis. In the 1980s this skepticism was dispelled as a number of generalizations of EU were proposed, most of which were capable of explaining evidence inconsistent with EU, while preserving transitivity and dominance. Generalized expected utility is now a flourishing subfield of economics, with dozens of competing models and considerable literature exploring their theoretical properties and comparing their empirical performance. But the EU model remains the principal tool for the analysis of choice under uncertainty. There is a view that generalized models are too difficult to handle or incapable of generating sharp results. This creates a need to show that the new models can be used in the kinds of economic analysis for which EU has been used, and that they can yield new and interesting results. This book meets this need by describing one of the most popular generalized models -- the rank-dependent expected utility model (RDEU), also known as anticipated utility, EU with rank-dependent preferences, the dual theory of choice under uncertainty, and simply as rank-dependent utility. As the many names indicate, the model has been approached in many ways by many scientists and for this reason, consideration of a single model sheds light on many of the concerns that have motivated the development of generalized utility models. The popularity of the RDEU model rests on its simplicity and tractability. The standard tools of analysis developed for EU theory may be applied to the RDEU model, but since RDEU admits behavior inconsistent with EU, the field of potential applications is widened. As such, the RDEU model is not as much a competitor to EU as an extension based on less restrictive assumptions.

Book Description
Expected utility provides simple, testable properties of the optimum behavior that should be displayed by risk-averse individuals in risky decisions. Simultaneously, given the existence of paradoxes under the expected utility paradigm, expected utility can only be regarded as an approximation of actual behavior. A more realistic model is needed. This is particularly true when treating attitudes toward small probability events: the standard situation for insurable risks. Non-Expected Utility and Risk Management examines whether the existing results in insurance economics are robust to more general models of behavior under risk.

Book Description
The proceedings contain a range of papers dealing with different issues relating to the theme of the workshop. The majority of them deal with model formulation and model analysis. A few deal with mathematical techniques that are needed to carry out model analysis. Some of the papers are theoretical whilst others are applied. As a result, the topics covered in these papers highlight the multifaceted nature of stochastic modelling and diversity of the applications of stochastic models.

Book Description
The Second International Conference on Foundations of Utility and Risk Theory was held in Venice, June 1984. This volume presents some of the papers delivered at FUR-84. (The First International Conference, FUR-82, was held in Oslo and some of the papers presented on that occasion were published by Reidel in the volume Foundations of Utility and Risk Theory with Applications, edited by Bernt P. Stigum and Fred Wenst~p). The theory of choice under uncertainty involves a vast range of controversial issues in many fields like economics, philosophy, psychology, mathematics and statistics. The idea of discussing these problems in international conferences has been successful: two conferences have been held and others will follow. The climate of the debate has changed in the meantime, partly as a result of these conferences. It is no more only a question of attacking or defending the neo-Bernoullian assumptions, but also of proposing wider generalizations and including new elements in the analysis of the decision process. For instance Amartya Sen - comparing the two current notions of rationality, internal consistency and self-interest pursuit introduces the concept of reasoning and considers the irrationality which may result from the failure of a positive correspondence between reasoning and choice or from a limited capacity of reasoning. Rationality is also considered with respect to the controversial axiom of strong independence. John C. Harsanyi introduces the concept of practical certainty, i. e.

Book Description
In a world filled with both enormous wealth and pockets of great devastation, how should the well-off respond to the world's needy? This is the urgent central question of Being Good in a World of Need. Larry S. Temkin, one of the world's foremost ethicists, challenges common assumptions about philanthropy, his own prior beliefs, and the dominant philosophical positions of Peter Singer and Effective Altruism. Filled with keen analysis and insightful discussions of philosophy, current events, development economics, history, literature, and age-old wisdom, this book is a thorough and sobering exploration of the complicated ways that global aid may incentivize disastrous policies, reward corruption, and foster “brain drains” that hinder social and economic development. Using real-world examples and illuminating thought experiments, Temkin discusses ethical imperialism, humanitarian versus developmental aid, how charities ignore or coverup negative impacts, replicability and scaling-up problems, and the views of the renowned economists Angus Deaton and Jeffrey Sachs, all within the context of deeper philosophical issues of fairness, responsibility, and individual versus collective morality. At times both inspiring and profoundly disturbing, he presents the powerful argument that neglecting the needy is morally impermissible, even as he illustrates that the path towards helping others is often fraught with complex ethical and practical perils. Steeped in empathy, morality, pathos, and humanity, this is an engaging and eye-opening text for any reader who shares an intense concern for helping others in need.

Book Description
Utilities Reform in 21st Century Australia: Providing the Essentials traces the development and consequences of the economic reform measures undertaken in the utilities sector in Australia (communications, energy, water/wastewater services, and transport) in the last years of the 20th century, and early decades of the 21st century. In doing so, it looks at the process of reform across industries, and across the state and federal jurisdictions, to identify what motivations the various governments had for pursing reform, how change varied across jurisdictions, and what issues arose in the process. Although by the mid-1990s all states and territories and the Australian Government were committed to reforming utilities as part of the National Competition Policy, not all pursued this reform with the same degree of speed and breadth of action. The broad trends of economic reform in Australia, and abroad, are also touched upon, to provide an outline of the wider context in which the reform of the utilities occurred. This book, therefore, explores the relationship between politics and society on the one hand and economic reform on the other; as well on as the efforts of governments in Australia to promote economic growth and the wealth of Australians in an increasingly complex and challenging global economic climate.
