Problem 13-27 (Algorithmic)
In a certain state lottery, a lottery ticket costs $3. In terms of the decision to purchase or not to purchase a lottery ticket, suppose that the following payoff table applies:
State of Nature | ||
Win | Lose | |
Decision Alternatives | s1 | s2 |
Purchase Lottery Ticket, d1 | 450000 | -3 |
Do Not Purchase Lottery Ticket, d2 | 0 | 0 |
a.
Expected value(d1) = (1/200000)*450000+(1-(1/200000))*(-3) =
-0.749985
Expected value d2 = (1/200000)*0+(1-(1/200000))*0 = 0
Recommended decision: Do Not Purchase Lottery Ticket as this decision has higher expected value
b.
Best payoff 450000 is assigned to utility of 10 and worst payoff -3 is assigned to utility value 0
Expected utility table
State of Nature | ||
Win | Lose | |
Decision Alternatives | s1 | s2 |
Purchase Lottery Ticket, d1 | 10 | 0 |
Do Not Purchase Lottery Ticket, d2 | 0.00001 | 0.00001 |
Expected utility(d1) = (1/200000)*10+(1-(1/200000))*0 =
0.00005
Expected utility (d2) = (1/200000)*0.00001+(1-(1/200000))*0.00001 =
0.00001
Recommended decision is Yes, Purchase Lottery Ticket as this decision has higher expected utility
Expected utility = 0.00005

State 2 81 256 .4 Value Act 1 Act 2 Probabilities State 1 16 0 .6 The modestly risk averse decision maker uses the square root utility function, i.e., U(x) - x050- x. A severely risk averse decision maker uses the fourth-root utility function, i.e., V(x) - x025 #3a, which act would the modestly risk averse decision maker choose via the maximum expected utility rule?

Problem 4-21 (Algorithmic) A real estate investor has the opportunity to purchase land currently zoned residential. If the county board approves a request to rezone the property as commercial within the next year, the investor will be able to lease the land to a large discount firm that wants to open a new store on the property. However, if the zoning change is not approved, the investor will have to sell the property at a loss. Profits (in thousands of...
