Preference

  • What is the difference between reflective preference and symmetric preference?
  • Unitary rule cannot be preference relation. (O / X)
  • Majority rule cannot be preference relation. (O / X)
  • Every preference on a finite set can be represented by a utility function. (O / X)
  • What is the meaning that the preference is โ€˜continuousโ€™?

Choice Function

  • When does a choice function be rationalizable?
  • Can you explain what is the property $\alpha$?

Utility Function

  • A convex preference needs a convex utility function. (O / X)
  • Can you give an example of convex/concave utility function for each?

Lottery

  • What is the meaning of the lottery preference is independent?

Bundle

  • What is the meaning of the bundle preference is convex?
  • What is the meaning of the bundle preference is monotone?
  • Can you give an example of non-monotone bundle preference?

Competitive Equilibrium

  • If Competitive Equilibrium occurs, then it is also Pareto stable. (O / X)
    • If yes, give an example.
    • If no, give a counter-example.
