Question 3

Aunt Rose owned a dress shop on 81st Street and Broadway in Manhattan, selling limited-edition dresses to wealthy clients.One day, her landlord tripled her rent.What effect would this have on her dress price in the short run, assuming she is following the rules of profit maximization?

Accepted Answer

Assuming she continues to operate, the higher rent will not affect dress prices in the short run.Rent is unrelated to the production cost of dresses; that is, it is a fixed cost.Only costs that enter into direct costs influence price.Fixed costs do not alter price or output of dresses in short-run profit maximization.
