Chapter 7 - The CPI and Cost of Living Flashcards
CPI
is a measure of the average of the prices paid by urban consumers for a fixed market basket of consumption goods and services
Calculating the CPI
CPI = Cost of CPI basket at current period prices / Cost of CPI basket at base period prices X 100
Inflation rate
the percentage change in the price level from one year to the next
(CPI in current year - CPI in previous year) / CPI in previous year X 100
Deflation
A situation in which the price level is falling and the inflation rate is negative
Sources of Bias in the CPI
1) New goods bias
2) Quality change bias
3) Commodity substitution bias
4) Outlet substitution bias
Two consequences of CPI bias
1) Distortion of private contracts
2) Decrease in government outlays and decrease in taxes
Alternative measures of the price level and inflation rate
1) GDP price index
2) Personal consumption expenditure
3) PCE prie index excluding food and energy
GDP Price index
is an average of the current prices of all the goods and services included in GDP expressed as a percentage of base-year prices.
Personal Consumption Expenditure PCE
is an average of the current prices of the goods and services included in the consumption expenditure component of GDP expressed as a percentage of the base-year prices.
PCE Price Index excluding food and energy
food and energy prices fluctuate much more than other prices. By excluding these highly variable items, the underlying price level and inflation trends can be seen more clearly.
Core inflation rate
The annual percentage change in the PCE price index excluding the price of food and energy
Dollars and cents at different dates
Price of stamp in 1911 = price of stamp in 1911 X CPI in 2011/CPI in 1911
Nominal wage rate
the average hourly wage rate measure in current dollars
Real wage rate
the average hourly wage rate measure in the dollars of a given reference year
Real wage rate = Nominal wage rate in 2011/CPI in 2011 X 100
Nominal wage rate
dollar amount of interest expressed as a percentage of the amount loaned. 1000 dollars in an account, you get 50 dollars interest at the end of year therefore 5 percent interest
