Question

Consider a sequential game between a shopkeeper and a haggling customer. The party who moves first chooses either a high price ($50) or low price ($20) and the second mover either agrees to the price or walks away from the deal and neither party gets anything. Ignore costs and assume the customer values the item at $60.
If the shopkeeper goes first and quotes a low price, what is the best response of the customer?

(A) Walk away from the deal
(B) ​Accept the low price happily
(C) ​Laugh at the storeowner
(D) ​Slam the storeowner’s door on the way out

Answer 1

Answer:

The correct answer is letter "B": Accept the low price happily.

Explanation:

As the purpose of the game was determining the price of a good out of the outcome of the sequential game, if the shopkeeper wins but chooses a low price ($20 according to the example), the shopkeeper will be playing to the customer's favor. The customer valued the item at $60 but only a $20 payment is needed. Then, there are $40 the customer will save out of the purchase, thus, it is likely the customer will take the price and walk away with the item happily.

Answer 2

Answer:

(B) ​Accept the low price happily

Explanation:

As the customer was willing to pay up to 60 dollars for the item, the offer of 50 dollars will be acceptable as it is creating a consumer surplus of 10 dollars.

The customer will look for his own benefit and to his judgement, the deal is good as it saves 10 dollars.

The amount earn by the seller is irrelevant.
