Let AE = Aggregate Expenditures, C = Consumption, I_P = Planned Investment, JG = Government Purchases. Consider a simple aggregate expenditures model, where
JAE = C + I_P + G and all components of aggregate expenditures except consumption are autonomous. All other things unchanged, a decrease in the price level

A) causes a movement up along a given aggregate expenditures curve and raises the equilibrium real GDP.
B) shifts the aggregate expenditures curve upwards and raises the equilibrium real GDP.
C) causes a movement down a given aggregate expenditures curve and lowers the equilibrium real GDP.
D) shifts the aggregate expenditures curve downwards and lowers the equilibrium real GDP.
