Chapter 13: GDP Pgs: 321-333
Gross Domestic Product • Market value of all final goods and services produced in the economy over a year
Final versus Intermediate • Final are goods either available to be purchased or purchased for final use. • Ex. Pastries and bicycles • Intermediate are goods purchased for resale or for use in making other goods. • Ex. Flour and aluminum
Components of GDP • Personal consumption expenditures • Gross private domestic investment • Government purchases of goods and services • Net exports of goods and services
Price Index • Measures the price level for a given period relative to the base period. • Nominal GDP is the measurement of GDP using current prices. • Real GDP is the measurement of GDP using constant prices. • GDP deflator is a weighted average of the prices of all final goods and services produced in the economy.
Formulas • Price Index=Price for period in question/Price in base period(multiply all this by 100) • Real GDP= Nominal GDP/Price Index(in decimal form) • Real GDP=Nominal GDP/GDP Inflator
Business Cycles • Fluctuations in the level of economic activity that are recurring • Four phases: expansion, peak, contraction, and trough • Expansion-real GDP has a rapid increase • Peak-real GDP maxes out • Contraction-real GDP decreases • Trough-real GDP bottoms out at a low point
Real GDP • 9/11 actually caused GDP to go up • More money was spent on clean-up, rescue, etc • People also demanded more security • People we not made better off which GDP doesn’t account for one’s well-being.
