Book Description
Within the prospect theory the paper examines production and hedging decisions of a competitive firm under price uncertainty. We consider the prospect theory for the firm's utility function in the two moment model known as (mu,sigma)-preference. In contrast to the literature our findings show that the production under uncertainty can be larger than in the certainty case. Furthermore, we demonstrate that although the futures markets are unbiased the firm is overhedging.

Book Description
In the years since it first published, Neuroeconomics: Decision Making and the Brain has become the standard reference and textbook in the burgeoning field of neuroeconomics. The second edition, a nearly complete revision of this landmark book, will set a new standard. This new edition features five sections designed to serve as both classroom-friendly introductions to each of the major subareas in neuroeconomics, and as advanced synopses of all that has been accomplished in the last two decades in this rapidly expanding academic discipline. The first of these sections provides useful introductions to the disciplines of microeconomics, the psychology of judgment and decision, computational neuroscience, and anthropology for scholars and students seeking interdisciplinary breadth. The second section provides an overview of how human and animal preferences are represented in the mammalian nervous systems. Chapters on risk, time preferences, social preferences, emotion, pharmacology, and common neural currencies—each written by leading experts—lay out the foundations of neuroeconomic thought. The third section contains both overview and in-depth chapters on the fundamentals of reinforcement learning, value learning, and value representation. The fourth section, “The Neural Mechanisms for Choice, integrates what is known about the decision-making architecture into state-of-the-art models of how we make choices. The final section embeds these mechanisms in a larger social context, showing how these mechanisms function during social decision-making in both humans and animals. The book provides a historically rich exposition in each of its chapters and emphasizes both the accomplishments and the controversies in the field. A clear explanatory style and a single expository voice characterize all chapters, making core issues in economics, psychology, and neuroscience accessible to scholars from all disciplines. The volume is essential reading for anyone interested in neuroeconomics in particular or decision making in general. Editors and contributing authors are among the acknowledged experts and founders in the field, making this the authoritative reference for neuroeconomics Suitable as an advanced undergraduate or graduate textbook as well as a thorough reference for active researchers Introductory chapters on economics, psychology, neuroscience, and anthropology provide students and scholars from any discipline with the keys to understanding this interdisciplinary field Detailed chapters on subjects that include reinforcement learning, risk, inter-temporal choice, drift-diffusion models, game theory, and prospect theory make this an invaluable reference Published in association with the Society for Neuroeconomics—www.neuroeconomics.org Full-color presentation throughout with numerous carefully selected illustrations to highlight key concepts

Book Description
There is broad theoretical and empirical evidence that investors exhibit a preference for skewness. However, there is little research regarding the extent to which individuals really favor positive skewness in individual decision making. In this dissertation, a controlled laboratory experiment is used to test for skewness preferences and prudence – a broader third-order risk preference that is closely linked to skewness preferences. Skewness and prudence preferences are further analyzed both within an Expected Utility Theory framework as well as with Cumulative Prospect Theory. For this, a sound experimental setup is used that also excludes any potentially distortionary effects from loss aversion. This dissertation therefore contributes to better understanding of individual risk preferences and other impact factors, such as a more “rational” vs. a more “intuitive” decision making process in individual decision making.

Book Description
Prospect Theory: For Risk and Ambiguity, provides a comprehensive and accessible textbook treatment of the way decisions are made both when we have the statistical probabilities associated with uncertain future events (risk) and when we lack them (ambiguity). The book presents models, primarily prospect theory, that are both tractable and psychologically realistic. A method of presentation is chosen that makes the empirical meaning of each theoretical model completely transparent. Prospect theory has many applications in a wide variety of disciplines. The material in the book has been carefully organized to allow readers to select pathways through the book relevant to their own interests. With numerous exercises and worked examples, the book is ideally suited to the needs of students taking courses in decision theory in economics, mathematics, finance, psychology, management science, health, computer science, Bayesian statistics, and engineering.

Book Description
This book explains how investor behavior, from mental accounting to the combustible interplay of hope and fear, affects financial economics. The transformation of portfolio theory begins with the identification of anomalies. Gaps in perception and behavioral departures from rationality spur momentum, irrational exuberance, and speculative bubbles. Behavioral accounting undermines the rational premises of mathematical finance. Assets and portfolios are imbued with “affect.” Positive and negative emotions warp investment decisions. Whether hedging against intertemporal changes in their ability to bear risk or climbing a psychological hierarchy of needs, investors arrange their portfolios and financial affairs according to emotions and perceptions. Risk aversion and life-cycle theories of consumption provide possible solutions to the equity premium puzzle, an iconic financial mystery. Prospect theory has questioned the cogency of the efficient capital markets hypothesis. Behavioral portfolio theory arises from a psychological account of security, potential, and aspiration.

Book Description
This paper presents a new two-parameter probability weighting function for Tversky and Kahneman (1992) cumulative prospect theory as well as its special cases -- Quiggin (1981) rank-dependent utility and Yaari (1987) dual model. The proposed probability weighting function can be inverse S-shaped (concave near probability zero and convex near probability one), S-shaped, globally convex and globally concave. Utility function of Yaari (1987) dual model with the proposed probability weighting function is a linear tradeoff between the lottery's expected value (i.e. the first L-moment), Gini (1912) mean difference statistic (or the second L-moment, known as L-scale) and the third L-moment (measuring the lottery's skewness). Two parameters of the proposed probability weighting function can be interpreted as a decision maker's sensitivity to the dispersion and skewness of lottery's outcomes. A decision maker who prefers positively skewed distributions (e.g., a small chance to win a highly desirable outcome) and dislikes negatively skewed distributions generally has an inverse S-shaped probability weighting function. This function crosses the 45° line at a probability smaller (greater) than 0.5 if a decision maker is also averse (attracted) to the dispersion of outcomes. Cumulative prospect theory with our proposed probability weighting function can rationalize the common ratio effect (i.e. a systematic fanning-out of indifference curves) in one type of common ratio problems as well as the reverse common ratio effect (i.e. a systematic fanning-in) -- in another type of common ratio problems, in accordance with the recent experimental evidence.
