of phone calls made. Provider B does not have a fixed service fee but instead charges $1 per minute for calls. Your friend‘s monthly demand for minutes of calling is given by the equation QD 5 150 2 50P, where P is the price of a minute.
a. With each provider, what is the cost to your friend of an extra minute on the phone? b. In light of your answer to (a), how many minutes would your friend talk on the phone with each provider?
c. How much would he end up paying each provider every month?
d. How much consumer surplus would he obtain with each provider? (Hint: Graph the demand curve and recall the formula for the area of a triangle.)
e. Which provider would you recommend that your friend choose? Why?
11. Consider how health insurance affects the quantity of healthcare services performed. Suppose that the typical medical procedure has a cost of $100, yet a person with health insurance pays only $20 out of pocket. Her insurance company pays the remaining $80. (The insurance company recoups the $80 through premiums, but the premium a person pays does not depend on how many procedures that person chooses to undertake.) a. Draw the demand curve in the market for medical care. (In your diagram, the horizontal axis should represent the number of medical procedures.) Show the quantity of procedures demanded if each procedure has a price of $100.
b. On your diagram, show the quantity of procedures demanded if consumers pay only $20 per procedure. If the cost of each procedure to society is truly $100, and if individuals have health insurance as just described, will the number of procedures performed maximize total surplus? Explain. c. Economists often blame the health insurance
