5. Exports –Imports • The reason why we subtract our imports from our exports is because: The Money we spend on goods imported from other countries takes money out of our economy.

6. Real GDP • This is an accurate measurement of how much the economy is growing. • Real GDP is when you use a price index to account for inflation.

7. Nominal GDP • Nominal GDP: is the GDP before accounting for inflation. • What was inflation again?

8. Why Inflation • Inflation is an increase in the prices of goods. • So we may actually be spending more money but not actually buying more goods. • This is why it must be taken into account when dealing with GDP

9. Consumer Price Index • Basket of Goods: Typical items bought by an average family in a month. • CPI = cost of today’s market basket divided by cost of market basket in previous year X 100. • CPI will give you the level of inflation, which is then subtracted from nominal GDP to give you real GDP
