Research in social and health psychology reports that smokers systematically underestimate the personal smoking risk. I build a model that captures potential determinants of smoking risk perceptions to investigate how smoking may cause an underestimation of the risk.

Decision theory

It seems that you're in Germany. We have a dedicated site for Germany. Whether we like it or not we all feel that the world is uncertain. From choosing a new technology to selecting a job, we rarely know in advance what outcome will result from our decisions. Unfortunately, the standard theory of choice under uncertainty developed in the early forties and fifties turns out to be too rigid to take many tricky issues of choice under uncertainty into account.

Decision making under uncertainty: Robust and data-driven approaches. A wide variety of decision problems in engineering, science and economics involve uncertain parameters whose values are unknown to the decision maker when the decisions are made. Ignoring this uncertainty can lead to inferior solutions that perform poorly in practice. Many decision problems under uncertainty also span across multiple time stages and thus involve adaptive decisions. Such problems are naturally formulated as multi-stage stochastic programs. Despite its wide applicability, stochastic programming suffers from three major shortcomings. Firstly, stochastic programming models assume precise knowledge of the probability distribution of the uncertain parameters, an assumption which may be difficult to justify in practice when only a finite number of historical observations is available.

Thomas V. Wesley J. Some of the experiments described here were supported by grants to the first author from the Graduate School of Business, University of Pittsburgh. Bonoma, Wesley J. Focusing on the validity of subjective expected utility SEU choice models for explaining decision making, this research developed a novel methodology that explains subjective probability and utility scales, assigns values on these defined scales to various consumer decision problems, and has individuals estimate missing decisional components. Results from seven experiments are reported. Oxford University Press is a department of the University of Oxford.

Decision making under uncertainty

Decision theory or the theory of choice not to be confused with choice theory is the study of an agent's choices. Decision theory is closely related to the field of game theory [2] and is an interdisciplinary topic, studied by economists, statisticians, data scientists, psychologists, biologists, [3] political and other social scientists, philosophers [4] and computer scientists. Empirical applications of this rich theory are usually done with the help of statistical and econometric methods. Normative decision theory is concerned with identification of optimal decisions where optimality is often determined by considering an ideal decision maker who is able to calculate with perfect accuracy and is in some sense fully rational. The practical application of this prescriptive approach how people ought to make decisions is called decision analysis and is aimed at finding tools, methodologies, and software decision support systems to help people make better decisions. In contrast, positive or descriptive decision theory is concerned with describing observed behaviors often under the assumption that the decision-making agents are behaving under some consistent rules. These rules may, for instance, have a procedural framework e.

Formal models have a long and important history in the study of human decision-making. They have served as normative standards against which to compare real choices, as well as precise descriptions of actual choice behavior. This chapter begins with an overview of the historical development of decision theory and rational choice theory and then reviews how models have been used in their normative and descriptive capacities. Models covered include prospect theory, rank- and sign-dependent utility theories and their descendants, as well as cognitive models of human decision-making like Decision Field Theory and the Leaky Competing Accumulator Model, which are based on basic psychological principles rather than assumptions of rationality.

Models of decision making under uncertainty: the criminal choice

In our everyday life we often have to make decisions with uncertain consequences, for instance in the context of investment decisions. To successfully cope with these situations, the nervous system has to be able to estimate, represent, and eventually resolve uncertainty at various levels. That is, not only are there different forms of uncertainty with different consequences for behavior and learning but research indicates that the processing of uncertainty highly depends on situation and context. The present research topic includes both review and original research articles that seek to shed light on the neural processes underlying decision making under uncertainty with a particular focus on situational and contextual influences. First, Bland and Schaefer review the diverse and often overlapping definitions of uncertainty.
