MV=PQ: A Resource for Economic Educators: Some Classroom Resources

Special thanks to Tim Schilling at MV=PQ blog for pointing out the Cleveland Fed’s interesting video series called the “Drawing Board”.

This video introduces the concept of Consumer Price Index as a measure of inflation in the United States, shows how CPI is calculated, and then goes into a bit more detail than perhaps the AP or IB student needs when it introduces a new method of measuring inflation used by the Fed called “median inflation”.

AP and IB students can benefit most from watching up to 4:12. In this first half of the video the CPI is defined, its measurement demonstrated, short-comings discussed and the “core CPI” explained.

Discussion Questions:

1. Why does the Bureau of Labor Statistics weight different items included in the measure of the consumer price index? What type of good gets a greater weights than others?
2. What are some of the purposes the CPI figure serves? Why do we care about changes in the price level in an economy?
3. What is one short-coming of the traditional method used for measuring the inflation rate using CPI?
4. Why did the BLS decide exclude oil and food prices from its “core CPI” figure?
