Economics 330T: Fall 2009 Helen Schneider Problem Set 1 SOLUTIONS I. Medical Care Costs 1. The CPI for hospital care (as one example) measures the cost of a two-person “hospital room and board” charge as an important part of the CPI hospital index. The cost of a day in the hospital has increased from \$200 in 1970 to \$1400 in 2000. The CPI was 38.8 in 1970 and 172.2 in 2000 and the Medical CPI was 34.0 in 1970 and 260.8 in 2000. (a) No, prices provided are nominal prices. Accounting for inflation using the general CPI reduced the price increase from \$200 to \$315.45 in 1970 dollars which is not nearly so dramatic. If you use the medical CPI, the price actually decreased from \$200 to \$182.52 in 1970 dollars. Alternatively, you may look at percentage changes in the CPI and express everything in year 2000 dollars. For example, percentage increase in medical care CPI is 6.67 ( 34 34 8 . 260 - ) while percentage change in the cost of a hospital bed is only 6 ( 200 200 1400 - ). Thus, hospital bed is actually cheaper than what we would expect if we account for medical care inflation. You may use different ways of accounting for inflation but your final answers will be the same.

### 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.
