How to prove that the independence axiom must be true for a set of preferences that can be represented by expected utility function?
Homework Answers
Expected utility theorem states that the value associated with a person's gamble is the statistical value that a person attaches to the result expected out of that trail. In order for a person's decision to be compliant with Expected utility Theorem, four axioms must hold true, namely: Completeness, Transitivity, Independence and Continuity.
Independence axiom states that the two gambling scenarios when combined with a third gambling scenario which is irrelevant to the preference, then the preference order remains same as that without the presence of third gambling option.

Cobb-Douglas Preferences: Cobb-Douglas preferences on the consump- tion set R2+ can be represented by a utility function of the form U (q1,q2) = Aq1αq2β, where A > 0, α ∈ (0,1), and β ∈ (0,1) are fixed parameters. 1. If we assume that preferences are ordinal, explain why these precise preferences are also represented by the utility function U(q ,q )=qγq1−γ, 1212 whereγ= α .Isγ∈(0,1)? (α+β) 2. If we assume that preferences are ordinal and restrict attention to the consumption...

The Independence Axiom of expected utility states that the preference relation is such that: L a L b ⇐⇒ αLa + (1 − α)L c αLb + (1 − α)L c . Note that ⇐⇒ means “is equivalent to.” What does is mean in the language of economics and finance?

Suppose that a decision-maker’s preferences over the set A={a, b, c} are represented by the payoff function u for which u(a) = 0, u(b) = 1, and u(c) = 4. (a) Give another example of a function f:A→R that represents the decision-maker’s preferences. (b) Is there a function that represents the decision-maker’s preferences and assigns negative numbers to all elements of A?
