Estimation of such models is usually done via parametric, semi-parametric and non-parametric maximum likelihood methods. Normative decision theory is concerned with identifying the best decisions by considering an ideal decision maker who is able to compute with perfect accuracy and is 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 under the assumption that the decision-making agents are behaving under some consistent rules.

These rules may, for instance, have a procedural framework e. Amos Tversky 's elimination by aspects model or an axiomatic framework, reconciling the Von Neumann-Morgenstern axioms with behavioral violations of the expected utility hypothesis, or they may explicitly give a functional form for time-inconsistent utility functions e.

The prescriptions or predictions about behaviour that positive decision theory produces allow for further tests of the kind of decision-making that occurs in practice. There is a thriving dialogue with experimental economics , which uses laboratory and field experiments to evaluate and inform theory. In recent decades, there has also been increasing interest in what is sometimes called "behavioral decision theory" and this has contributed to a re-evaluation of what rational decision-making requires. The area of choice under uncertainty represents the heart of decision theory.

Petersburg paradox to show that expected value theory must be normatively wrong. He gives an example in which a Dutch merchant is trying to decide whether to insure a cargo being sent from Amsterdam to St Petersburg in winter. In his solution, he defines a utility function and computes expected utility rather than expected financial value see [10] for a review.

In the 20th century, interest was reignited by Abraham Wald's paper [11] pointing out that the two central procedures of sampling-distribution-based statistical-theory, namely hypothesis testing and parameter estimation , are special cases of the general decision problem. Wald's paper renewed and synthesized many concepts of statistical theory, including loss functions , risk functions , admissible decision rules , antecedent distributions , Bayesian procedures , and minimax procedures.

The phrase "decision theory" itself was used in by E. The revival of subjective probability theory, from the work of Frank Ramsey , Bruno de Finetti , Leonard Savage and others, extended the scope of expected utility theory to situations where subjective probabilities can be used. The work of Maurice Allais and Daniel Ellsberg showed that human behavior has systematic and sometimes important departures from expected-utility maximization.

The prospect theory of Daniel Kahneman and Amos Tversky renewed the empirical study of economic behavior with less emphasis on rationality presuppositions. Kahneman and Tversky found three regularities — in actual human decision-making, "losses loom larger than gains"; persons focus more on changes in their utility-states than they focus on absolute utilities; and the estimation of subjective probabilities is severely biased by anchoring.

Intertemporal choice is concerned with the kind of choice where different actions lead to outcomes that are realised at different points in time. If someone received a windfall of several thousand dollars, they could spend it on an expensive holiday, giving them immediate pleasure, or they could invest it in a pension scheme, giving them an income at some time in the future. What is the optimal thing to do? The answer depends partly on factors such as the expected rates of interest and inflation , the person's life expectancy , and their confidence in the pensions industry.

However even with all those factors taken into account, human behavior again deviates greatly from the predictions of prescriptive decision theory, leading to alternative models in which, for example, objective interest rates are replaced by subjective discount rates. Some decisions are difficult because of the need to take into account how other people in the situation will respond to the decision that is taken.

The analysis of such social decisions is more often treated under the label of game theory , rather than decision theory, though it involves the same mathematical methods. From the standpoint of game theory most of the problems treated in decision theory are one-player games or the one player is viewed as playing against an impersonal background situation.

Other areas of decision theory are concerned with decisions that are difficult simply because of their complexity, or the complexity of the organization that has to make them. Individuals making decisions may be limited in resources or are boundedly rational have finite time or intelligence ; in such cases the issue, more than the deviation between real and optimal behaviour, is the difficulty of determining the optimal behaviour in the first place.

One example is the model of economic growth and resource usage developed by the Club of Rome to help politicians make real-life decisions in complex situations [ citation needed ]. Decisions are also affected by whether options are framed together or separately; this is known as the distinction bias. In , Dwayne Rosenburgh explored and showed how decision theory can be applied to complex decisions that arise in areas such as wireless communications.
