Choices, Values, and Frames

The volume argues that people evaluate outcomes relative to a reference point rather than in absolute terms, and that losses are weighted more heavily than equivalent gains. This produces framing effects: logically equivalent descriptions of the same choice—framed as gains or as losses—yield systematically different preferences. The framework rejects expected-utility theory's assumption that preferences are stable, context-independent, and defined over final wealth states. Prospect theory, first stated by Kahneman and Tversky in 1979, replaces the utility function with a value function defined over gains and losses and replaces objective probabilities with decision weights that overweight small probabilities and underweight moderate and large ones. The volume assembles the papers that developed, tested, and applied this framework across two decades.

The volume consolidates prospect theory and its components: reference dependence, loss aversion, diminishing sensitivity in the value function, and probability weighting. It also gathers the framing literature, including the Asian disease problem and other demonstrations that preference reverses under logically equivalent descriptions. These concepts are now standard in behavioral economics, finance, marketing, public policy, and medical decision making. Loss aversion informs everything from insurance pricing to the endowment effect; framing effects inform risk communication and policy design; probability weighting informs models of gambling and insurance behavior. The collection is the standard reference for the empirical and theoretical papers behind these ideas, though individual papers are also widely cited in their original journal form.

The 1982 volume, co-edited by Kahneman, Slovic, and Tversky, assembled the descriptive findings on heuristics and biases—representativeness, availability, anchoring, and their consequences for judgment under uncertainty. Choices, Values, and Frames (2000) focuses on choice and preference rather than judgment, and it assembles the prospect theory and framing papers. The two volumes are complementary: the 1982 collection established that judgment deviates systematically from normative standards, while the 2000 collection established that preference and choice do as well. Both are edited collections, and both are reference points for the heuristics-and-biases paradigm. The 2000 volume includes a retrospective essay by Kahneman that frames the program's development and its relationship to later work.

A frequent misreading treats prospect theory as a general theory of decision making that replaces expected utility across all domains. In fact, the theory was developed to describe choice under risk with modest stakes, and its status as a general account of preference remains contested. Later research, including work by Matthew Rabin and others, raised questions about the theory's assumptions, particularly the implausibility of the value function's curvature for large stakes. Other critics, including Gerd Gigerenzer, argued that heuristics should be understood as adaptive tools rather than as sources of bias. The volume itself presents prospect theory as a descriptive framework that departs from expected utility, not as a complete theory of rational or irrational choice, and readers should consult the later literature for the ongoing debate.

The volume was edited by Daniel Kahneman and Amos Tversky and published by Cambridge University Press in 2000, several years after Tversky's death in 1996. It collects papers that originally appeared in journals including Econometrica, Science, and the Journal of Risk and Uncertainty, along with some new contributions. The editors' introductions frame the papers and trace their development, but the volume is a compilation rather than a unified monograph, and individual chapters can be read independently. Readers should be aware that the papers appear in their original form, sometimes with minor edits, and that subsequent developments in behavioral economics are not fully reflected. The volume is a historical and theoretical reference rather than a current statement of the field.

Prospect theory remains one of the most influential frameworks in the social sciences, and the volume's core concepts—reference dependence, loss aversion, and framing—are standard. However, the framework has been refined and in some respects challenged. The replication crisis in psychology raised questions about effect sizes for some classic findings, though loss aversion and framing effects have generally survived. Later work distinguished loss aversion from other reference-dependent phenomena and proposed alternative models. Behavioral economics has moved from documenting anomalies to designing interventions, and some of that work draws on prospect theory while other strands rely on different models. The volume is now cited as a historical and theoretical landmark rather than as a current statement of the field's frontier.
