Decision-making under uncertainty: theory, experiments, and applications


The aim of this course is to present an overview of the main developments in decision theory up to today’s research frontier. We start with classical theory and observed deviations from it. We will then discuss newer developments, which violate some of the classical assumptions. It will be argued that these deviations are not necessarily irrational. Thus, the course does not directly deal with psychological biases or “mistakes”. Applications to macroeconomics, financial markets, and marketing will be discussed.



  •  Basic notions of order theory
  •  Preference relations 
  • Decision under certainty: utility maximization
  • Choice Theory: Weak Axiom of Revealed Preferences and utility characterization
  •  Choice under risk: von Neumann and Morgenstern's Expected Utility
  • Choice under uncertainty: Subjective Expected Utility (de Finetti, Savage, and AnscombeAumann models)
  •  Experimental violations of Subjective Expected Utility
  •  Generalizations: Ambiguity models (Choquet and Maxmin Expected Utility)
  • Generalizations: Incomplete preferences under uncertainty (Bewley model)


  • Case-based decision theory
  •  Dynamic choices and updating/learning
  • Models of unawareness
  • Menu-choice models: demand for flexibility, role of temptation and desire for self-control


There is no required book. But, standard references are:

  •      D. Kreps, Notes on the Theory of Choice, Westview, 1988
  •  L. J. Savage, The Foundations of Statistics, Dover, 1954 (not an easy read)

The following references should help providing a general overview of decision theory:

  •    I. Gilboa, Theory of Decision under Uncertainty, Cambridge, 2009
  •  E. Dekel and B. Lipman (2010), How (not) to do decision theory, Annual Review of Economics, 2, 257-82
  • F. Gul and W. Pesendorfer 2008, The case for mindless economics, in The Foundations of Positive and Normative Economics: A Handbook, A. Caplin and A. Schotter eds., Oxford 

An optional reading list of research papers for topics covered in class as well as additional topics will be provided.
