Answer to Question 2
a. Output = 110, Price = 21 whereby MR = MC. The barber shop will minimize its losses since P > AVC.
b. The economic loss = 440 (total revenue = 21 110 = 2,310; total cost = 25 110 = 2,750 ).
c. Short-run losses will lead some firms to exit the market. As a result, the demand curve for a firm remaining in the market will shift to the right and become less elastic. Exit continues until economic losses are eliminated and each firm breaks even.
d. No, its demand increases and becomes less elastic. It will produce a larger quantity.
