GDP
70 % 18 % 20 %
-

AE =
C +
I +
G +
(X M)-
·
C =
consumer spending
:
all spending on newly produced
goods and services bu individuals and households
·
does not include used goods (thrifting , old house) new homes +
I private investment spending spending by firms

produced physical capitol and newly produced homes
·
G =
government purchases spending by the government
: of

payments
·
(X-M) :
net exports the value of all exports minus
:
imports
