LEARNINGOBJECTIVES:
Bytheendofthischapter,studentsshouldunderstand:
whyaneconomy'stotalincomeequalsitstotalexpenditure.
howgrossdomesticproduct(GDP)isdefinedandcalculated.
thebreakdownofGDPintoitsfourmajorcomponents.
thedistinctionbetweenrealGDPandnominalGDP.
whetherGDPisagoodmeasureofeconomicwell-being.
CONTEXTANDPURPOSE:

themacroeconomy—GDPandtheconsumerpriceindex.Chapter10developshoweconomists

developshoweconomistsmeasurethelevelofpricesinthemacroeconomy.Takentogether,
Chapter10concentratesonthequantityofoutputinthemacroeconomywhileChapter11
concentratesonthepriceofoutputinthemacroeconomy.
Thepurposeofthischapteristoprovidestudentswithanunderstandingofthe

KEYPOINTS:
?Becauseeverytransactionhasabuyerandaseller,thetotalexpenditureintheeconomymust
equalthetotalincomeintheeconomy.
?Grossdomesticproduct(GDP)measuresaneconomy'stotalexpenditureonnewlyproduced
goodsandservicesandthetotalincomeearnedfromtheproductionofthesegoodsand

withinacountryinagivenperiodoftime.
?GDPisdividedamongfourcomponentsofexpenditure:consumption,investment,
governmentpurchases,andnetexports.Consumptionincludesspendingongoodsand
servicesbyhouseholds,withtheexceptionofpurchasesofnewhousing.Investmentincludes
