You must show your calculations. 1) Suppose you are the owner of a health insurance company. In exchange for a premium, you pay the medical expenses for two types of customers: smokers and non-smokers. Over the course of a year, 50% of smokers incur medical bills of \$600 and 20% of non-smokers incur medical bills of \$120. Finally, suppose that the world consists of 50 smokers and 50 non-smokers. a. If you can determine who is a smoker and who is a non-smoker, what is the minimum premium you should charge smokers and non-smokers? b. Now assume you do not know which of the customers are smokers and which are non-smokers. If you can only charge a single premium, what premium do you charge to all of your policy holders? c. What is your profit from charging the premium found in part b? What happens to the smokers and non-smokers in this market?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
