Question

1. aggregate demand: is the equal to the total of consumption, investment, government, and net export expenditures. is the total quantity of output demanded at alternative price levels. equals aggregate supply at macro equilibrium. all of the above

Explanation:

Aggregate demand is calculated as \(AD = C + I+G + (X - M)\) (where \(C\) is consumption, \(I\) is investment, \(G\) is government spending, \(X\) is exports and \(M\) is imports), so it is the total of consumption, investment, government, and net - export expenditures. It represents the total quantity of output demanded at alternative price levels. In macro - equilibrium, aggregate demand equals aggregate supply (\(AD = AS\)).

Answer:

all of the above
