This article described three heuristics that are employed in making judgements under uncertainty: representativeness, which is usually employed when people are asked to judge the probability that an object or event A belongs to class or process B; availability of instances or scenarios, which is often employed when people are asked to assess the frequency of a class or the plausibility of a particular development; and adjustment from an anchor, which is usually employed in numerical prediction when a relevant value (...) is available. These heuristics are highly economical and usually effective, but they lead to systematic and predictable errors. A better understanding of these heuristics and of the biases to which they lead could improve judgements and decisions in situations of uncertainty. (shrink)

There is an idea, extremely common among social contract theorists, that the primary function of social institutions is to secure some form of cooperative benefit. If individuals simply seek to satisfy their own preferences in a narrowly instrumental fashion, they will find themselves embroiled in collective action problems – interactions with an outcome that is worse for everyone involved than some other possible outcome. Thus they have reason to accept some form of constraint over their conduct, in order to achieve (...) this superior, but out-of-equilibrium outcome. A social institution can be defined as a set of norms that codify these constraints.1 Simplifying somewhat, one can then say that social institutions exist in order to secure gains in Pareto-efficiency.

This is an introductory 2001 textbook on probability and induction written by one of the world's foremost philosophers of science. The book has been designed to offer maximal accessibility to the widest range of students and assumes no formal training in elementary symbolic logic. It offers a comprehensive course covering all basic definitions of induction and probability, and considers such topics as decision theory, Bayesianism, frequency ideas, and the philosophical problem of induction. The key features of this book are a (...) lively and vigorous prose style; lucid and systematic organization and presentation of ideas; many practical applications; a rich supply of exercises drawing on examples from such fields as psychology, ecology, economics, bioethics, engineering, and political science; numerous brief historical accounts of how fundamental ideas of probability and induction developed; and a full bibliography of further reading.

Ainslie argues that our responses to the threat of our own inconsistency determine the basic fabric of human culture. He suggests that individuals are more like populations of bargaining agents than like the hierarchical command structures envisaged by cognitive psychologists. The forces that create and constrain these populations help us understand so much that is puzzling in human action and interaction: from addictions and other self-defeating behaviors to the experience of willfulness, from pathological over-control and self-deception to subtler forms of (...) behavior such as altruism, sadism, gambling, and the 'social construction' of belief. This book integrates approaches from experimental psychology, philosophy of mind, microeconomics, and decision science to present one of the most profound and expert accounts of human irrationality available. It will be of great interest to philosophers and an important resource for professionals and students in psychology, economics and political science. (shrink)

The result of two key social developments in recent years are examined here: the partial dismantling of the welfare state and the progress of genetics. Genetic insights are increasingly valuable for risk assessment, and insurers would like to use these insights to help determine premiums. Combined with the fact that social welfare is being curtailed, this could potentially create an uninsured high-risk population. Along with considerations of autonomy and privacy, this is the basis for an ethical critique of insurer's access (...) to information. The result has often been regulation of such information; but the authors argues that due to adverse selection, regulation will not solve these problems, and this may jeopardize the survival of private personal insurance. Instead, we should look towards the resurrection of social insurance, a key component of the welfare state. This will interest academic researchers as well as professionals involved with genetics and insurance. (shrink)

What makes insurance special among risk technologies is the particular way in which it links solidarity and technical rationality. On one hand, within insurance practices ‘risk’ is always defined in technical terms. It is related to monetary measurement of value and to statistical probability calculated for a limited population. On the other hand, and at the same time, insurance has an inherent connection to solidarity. When taking out an insurance, one participates in the risk pool within which each member is (...) reciprocally responsible for others’ risks. The combination of technical controllability and solidarity has made insurance a successful tool for governing welfare societies during the twentieth century. From the point of view of business ethics, it is interesting that, as we argue in this article, the connection between insurance and solidarity is not limited to social welfare assemblages, but is evident in relation to private insurance as well. At the same time, however, it is important to understand that insurance does not advance all forms of solidarity. Hence, this theoretical article analyzes the specific conceptions of solidarity that the different forms of insurance practice produce. Particular emphasis is put on the distinction between ‘chance solidarity’ and ‘subsidizing solidarity’. The main questions of the article are: What kinds of conceptions of solidarity are built in the insurance technology? And how are the limits of solidarity defined and justified in different forms of insurance? (shrink)

Pollution, higher traffic noise, or a poisoned river are all examples of externalities---costs which are imposed by an action but which are not built in to the price of that action. One of the problems of economic theory is whether, when analysing the desirability of a new road, for example, the costs that occur as externalities can be fully incorporated into the price of that road. Dr Andreas Papandreou has provided a book which fully explains and analyses the ideas lying (...) behind the theory of externalities. Papandreou has made a survey of the various methodological approaches taken by economists to the issue of eternalities, and the failure of some markets to reconcile individual and social costs and benefits. He tackles the difficult issue of defining or characterizing externalities, surveys the current literature, and investigates the effect that externality theory has had on major economic issues. His major theme is an exploration of institutional inefficiency and the implications of incorporating organizational costs into economic models. Written in a non-technical style, this book is suitable not only for those economists who make a study of externalities, but for those who need to understand the theory for their own fields of research, and for postgraduate students.

Few issues in business ethics are as polarizing as the practice of risk classification and underwrit­ ing in the insurance industry. Theorists who approach the issue from a background in economics often start from the assumption that policy-holders should be charged a rate that reflects the ex­ pected loss that they bring to the insurance scheme. Yet theorists who approach the question from a background in philosophy or civil rights law often begin with a presumption against socalled “actuarially fair” premiums (...) and in favor of “community rating,” in which everyone is charged the same price. This paper begins by examining and rejecting the three primary argu­ ments that have been given to show that actuarially fair premiums are unjust. It then considers the two primary arguments that have been offered by those who wish to defend the practice of risk classification. These arguments overshoot their target, by requiring a “freedom to under­ write” that is much greater than the level of freedom enjoyed in most other commercial transac­ tions. The paper concludes by presenting a defense of a more limited right to underwrite, one that grants the legitimacy of the central principle of risk classification, but permits specific deviations from that ideal when other important social goods are at stake.
