Decision Making under Uncertainty

Seminar

gehalten von Prof. Dr. Eva Lütkebohmert-Holtz and Dr. Lorenz Hartmann

 

Inhalt

This seminar is on the theory of decision making under uncertainty. We cover both risk and non-calculable risk (ambiguity). We will discuss the most important models in decision theory such as expected utility theory, prospect theory, subjective expected utility theory and maxmin expected utility theory. We focus on the axiomatic foundations of these models as well as how these models can be applied and empirically tested. We discuss famous decision-theoretic “paradoxes” such as the St. Petersburg Paradox, the Ellsberg Paradox and the Allais Paradox. We discuss how these paradoxes can be resolved with the introduced models. Towards the end of the course we study how models on ambiguity can be applied to strategic interaction (games) and how this can explain empirically observed deviations from the Nash Equilibrium prediction.

Overall this seminar is theoretical, however a main focus will also be on examples and applications. Required knowledge is a solid understanding of the basic principles of Microeconomics. A more pronounced background in Economics and/or Mathematics is helpful but not required. The student should be interested and curious about how human decision making can be modelled and tested.

The following topics are the main building blocks of the seminar:

 

1.     What is Decision Theory? We discuss the concepts of states of the world, consequences, acts and preferences as well as the role of axioms in decision theory. We illustrate this by means of examples.

2.     Decision making under risk: expected utility theory, prospect theory, St. Petersburg Paradox, Allais Paradox.

3.     De Finetti's approach to decision making under uncertainty and its relationship to finance and no arbitrage arguments.

4.     “The crowning glory of choice theory”: Savage's famous subjective expected utility theory.

5.     Decision making under ambiguity: the Ellsberg Paradox, Choquet expected utility theory and Maxmin expected utility theory.

6.     Ambiguous games: explaining deviations from Nash equilibrium with ambiguity.
