Inflation, Unemployment, and Employment
The GDP deflator • Definition: • GDP deflator = nominal GDP/real GDP • A by-product of measuring real GDP • Provides a measure of “average” prices in the economy • Sometimes called implicit price deflator
A measure of the inflation rate • Inflation rate: the percent change in the deflator from one period to the next • (Pt - Pt-1)/Pt-1 stated in percent • (1.128 - 1.126)/1.126 = .002 or .2 percent • At an annual rate this is .8 percent as stated in the WSJ news story
Recap of our discussion of GDP • Enough now to read and do “critical thinking” about the typical news story • But remember that GDP is not perfect • misses things: Home Work (two words), underground economy • not the only measure of well-being • For international comparisons, we must take account of exchange rates and “purchasing power” differences in different countries
Consumer price index (CPI) • based on a fixed market basket of goods and services that a “typical” person purchases • How much more does that market basket cost this year than last year? • Answer (in percentage terms) is the inflation rate using the CPI • Example 50 cartons of milk, 300 cookies • 1998: 2.00x50 + 1x300 = 400 • 1997: 1.50x50 + .5x300 = 225 • 400/225 = 1.78: inflation rate would be 78%
CPI Inflation Bias • Many complain that the CPI gives an upward biased measure of inflation • misses quality improvements • market basket changes • indexing social security makes this an important public policy issue • commission chaired by Michael Boskin of Stanford found the bias was about 1 percent (maybe larger)
How do inflation rates based on the CPI and GDP deflator compare?
Unemployment Rate • A major economy-wide labor market indicator • cyclical • frictional and structural • concept of natural unemployment rate • natural does not mean “good”
As stated in this WSJ article, the October unemployment rate is to be released tomorrow
Other Economy-Wide Labor Market Indicators • Employment (total number of jobs) • Labor Force Participation Rate • Employment-To-Population Ratio
Unemployment data are collected by the U.S. Department of Labor • Let’s take a look at the DOL web page to see what’s happening • You can enter through Econ1 web page
