Rather than having a single base year, the CPI has a base period

price index

a number that compares prices in one year with some earlier base year This helps to measure the change sin the overall price level. It is always cited along with the year for which the aggregate price level is being measured and the base year This can also measure inflation.

achieved by an economy if it produces at a point on its Production Possibilities curve (pg. 18) this happens when you use the least- cost method of production

increase of real GDP indicate

an economy is producing MORE

Price Index Formula

basket price/basket price in base year x 100
