Go to www.gpoaccess.gov/eop/, the Web site for the Economic Report of the President. On the left of the screen, go to "Downloadable Reports/Tables" and in the "Statistical Tables" click on 2010. In the tables, use Table B.42, "Civilian Unemployment Rate, 1962-2009" to obtain the annual unemployment rate and Table B.60, "Consumer Price Indexes for Major Expenditure Classes, 1965-2009," to obtain the annual consumer price index (CPI). Using the CPI value for all items, calculate the annual inflation rate from 1966 to the present. Note that the tables in the Economic Report of the President are Excel spreadsheets, so the annual inflation rate can be easily calculated using the formula for the inflation rate with Excel's formula bar. For each of the following periods, does the relationship between the annual unemployment rate and the annual inflation rate support a movement along the short-run Phillips curve or a shift in the Phillips curve? And if it supports a shift, was it a negative shock or a positive shock?
