GROSS DOMESTIC PRODUCT
GDP = the total dollar value of all

GDP = (C) + (I) + (G) + (X-M)
(C)- consumption by individuals
(I)- Investment in capital by
businesses
(G)- government spending
(X-M)- net exports
INFLATION
- A prolonged rise in the general price
level of goods and services.
- makes your dollar worth less.
- causes the purchasing power of
your dollar to be less.
- determines the value of your money
over time.
- use tools like the CPI to check for
inflation over time.
