Definition
inflation
Term
Inflation is
Definition
a situation where the overall level of prices is increasing
Term
GDP deflator equation
Definition
Nominal GDP/real GDP * 100
Term
Real GDP equation
Definition
Nominal GDP/ GDP deflator * 100 (manipulation of GDP deflator formula)
Term
Consumer Price Index..
Definition
Measures the overall cost of the goods and services bought by a typical consumer.
Term
CPI measures:
Definition
purchasing power and inflation
Term
CPI formula
Definition
price of the basket of goods and services in a given year/price of the basket in the base year * 100

Definition
the cost of living
Term

Definition
a constant standard of living.

Definition
MORE
Term

Definition
CPI in year Y - CPI in Year X / CPI in year X * 100
Term
Use CPI to "correct" ...
Definition
income and interest rates for the effects of inflation
Term
Value in year X dollars formula
Definition
Value in year Y dollars * (CPI in year X/ CPI in year Y)
Term
Real interest rate formula
Definition
nominal interest rate-inflation
Term
Problems with calculating CPI?
Definition
Substitution bias, Introduction of new goods, and unmeasured quality change
Term
Substitution bias:
Definition
over time, some prices rise more than others so even if your income is increasing you are going to substitute towards goods that are less expensive. CPI doesn't acknowledge this and will overstate the increase in the cost of living (overstate inflation)
Term
Introduction of new goods:
Definition
increases the value of the dollar because prices decrease. The CPI is based on a fixed consumer basket and overstates the increase in the cost of living.
Term
Unmeasured Quality Change:
Definition
if the quality of a good rises, then the value of the dollar is rising even though prices stayed the same. CPI overstates inflation
Term
How much does CPI overestimate inflation each year?
Definition
approximately 1 percent
Term
GDP deflator is also a price index, like CPI..how are they Different?
Definition
GDP deflator is calculated using the prices of all goods and services produced domestically. CPI uses the prices of goods bought by consumers only, regardless where they were produced.

The GDP deflator is calculated each year where the CPI is only calculated when the Bureau of Labor Statistics chooses. CPI rises slightly faster than the GDP deflator because of substitution bias and the bias associated with the intro of new goods.
Term
