Test questions

Here you can find a list of questions/problems for the final test. The list is now complete.


Decision under uncertainty

  • What is certainty equivalent?
  • Explain independence axiom.
  • What is common consequence effect? What are the implications for EUT?
  • What is common ratio effect?  What are the implications for EUT?
  • There is an evidence that people systematically deviate from EUT. Describe the pattern.
  • Suppose that you elicit certainty equivalents (CE) for lotteries where you get higher amount with probability p and smaller amount with probability 1-p. How would you expect that CE depends on p?
  • Explain the concept of probability weighting (PW). Highlight differences between PW and expected utility theory (EUT).
  • Describe main elements of rank-dependent utility theory?
  • Suppose that you have  lotteries where you get higher amount with probability p and smaller amount with probability 1-p. How would you interpret the probability weighting function w(p) in this particular case?
  • Describe the common (i.e. empirically observed) shape of  the probability weighting function.
  • Describe the observed heterogeneity in the shape of  the probability weighting function?
  • What is endowment effect? How does it relate to loss-aversion?
  • Discuss how market experience affects endowment effect (your argumentation should be based on some academic paper). 
  • Explain the concept of reference point.
  • Explain the concept of loss-aversion.
  • Explain a difference between rank-dependent utility theory and prospect theory? 
  • Name and shortly describe some field evidence for loss-aversion (your answer should be based on some academic paper).
  • What is considered to be a reference point? List and explain main possibilities.
  • Prospect theory assumes particular shape of the value function. Plot it and explain. 


Information and biases

  • Describe rational benchmark for dealing with new information.
  • Describe confirmatory bias and give examples of evidence that documents the bias.
  • Discuss how the confirmatory bias depends on the desirability of new information (i.e. good vs. bad news)
  • Explain and give example of evidence for hot hand fallacy and gambler's fallacy.
  • Explain overconfidence and list manifestations of overconfidence.
  • Give examples of some field evidence (i.e. coming from real world not laboratory) for overconfidence bias.
  • Explain projection bias by using O'Donoghue and Rabin model.
  • Give example of evidence for porjection bias. 


Fairness and social preferences

  • Give several examples of evidence that people have social (other-regarding) preferences.
  • Describe ultimatum game and typically observed behavior in this game.
  • Describe gift-giving game and typically observed behavior in this game.
  • Write down and interpret the inequality aversion utility function.
  • Explain the main criticism of Fehr-Schmidt model (i.e. inequality aversion).
  • Explain the main differences between theories based on distributional prefences and reciprocity. 
  • Give several examples of evidence for reciprocity theories of social preferences.
  • Give example of evidence that monetary incentives can crowd out intrinsic motivation.
  • Explain the role of observability in situations when  monetary incentives can crowd out intrinsic motivation. Give example of some evidence that supports your explanation.
  • Describe the basic setup of Benabou and Tirole model of intrinsic motivation and reputational concerns. What effects are in place when monetary incentives become stronger.
  • Describe public goods game and typically observed behavior in this game.
  • What types  of players are usually identified in public goods game? What is the consequence for observed outcome in public goods game?
  • What is the effect of punishment in public goods game? What is the anti-social punishment?


Time preferences

  • Write down and explain exponential discounting utility function.
  • List and explain main properties of  exponential discounting  model?
  • Define time-consistency. How is it related to exponential discounting?
  • Describe so called MEL (money earlie or later) experiements?
  • Discuss the conditions under which MEL experiments measure time preferences (i.e. discounting).
  • Besides MEL, what other approaches can be used to measure time preferences? Give examples.
  • What is the common difference effect?
  • Discuss the empirical relationship between time preferences and individual traits (e.g. age, gender, etc.)
  • Write down and explain hyperbolic discounting utility function. 
  • Write down and explain quasi-hyperbolic discounting utility function.
  • Plot and show differences between shapes of exponential, hyperbolic and quasi-hyperbolic utility functions.
  • Explain the concept of present-biased preferences?
  • Describe the model of multiple-selves? What types of decision makers can be distinguished in this model.
  • Give example of several empirical phenomena that can be explained by time-incosistent preferences?
