Question

The city of​ Belgrade, Serbia, is contemplating building a second airport to relieve congestion at the main airport and is considering two potential​ sites, X and Y. Hard Rock Hotels would like to purchase land to build a hotel at the new airport. The value of land has been rising in anticipation and is expected to skyrocket once the city decides between sites X and Y.​ Consequently, Hard Rock would like to purchase land now. Hard Rock will sell the land if the city chooses not to locate the airport nearby. Hard Rock has four​ choices: (1) buy land at​ X, (2) buy land at​ Y, (3) buy land at both X and​ Y, or​ (4) do nothing. Hard Rock has collected the following data​ (which are in millions of​ euros): 

                                                                          X          Y

Current purchase price                                     26      22

Profits if airport and hotel built at this site       50      40

Sale price if airport not built at this sit              11       5

Hard Rock determines there is a 55​% chance the airport will be built at X​ (hence, a 45​% chance it will be built at​ Y).

Expert Solution
Step 1

The payoff at the airport X is shown below

The Payoff to buy land at X=Profit of an airport built at site X-  Current purchase at site X                                                                                             = 50-26

                                           = 14

The Payoff to buy land at Y = Sale price at Y- Current purchase at site Y

                                             = 5-22

                                             = -17

Payoff to buy land at X and Y = The Payoff to buy land at X+The Payoff to buy land at Y

                                                = 14+(-17)

                                                = -3

Payoff to do nothing = 0
