Chapter10concentratesonthequantityofoutputinthemacroeconomywhileChapter11

concentratesonthepriceofoutputinthemacroeconomy.

Thepurposeofthischapteristoprovidestudentswithanunderstandingofthe

KEYPOINTS:

•Becauseeverytransactionhasabuyerandaseller,thetotalexpenditureintheeconomymust

equalthetotalincomeintheeconomy.

•Grossdomesticproduct(GDP)measuresaneconomy'stotalexpenditureonnewlyproduced

goodsandservicesandthetotalincomeearnedfromtheproductionofthesegoodsand

withinacountryinagivenperiodoftime.

•GDPisdividedamongfourcomponentsofexpenditure:consumption,investment,

governmentpurchases,andnetexports.Consumptionincludesspendingongoodsand

servicesbyhouseholds,withtheexceptionofpurchasesofnewhousing.Investmentincludes

spendingonnewequipmentandstructures,includinghouseholds,purchasesofnewhousing.

Governmentpurchasesincludespendingongoodsandservicesbylocal,state,andfederal
