Extracted text: YAS = 742 + 15 P- 28Poil YAD = 478 - 45P + 18G Suppose initially, the Poil = $93 per barrel and government spending is equal to $630. %3D Part (a): Calculate equilibrium GDP and the price level. Part (b): Determine the magnitude of the multiplier if oil prices exogenously rise by $1. Part (c): Using 2 to 3 sentences, provide a theoretical explanation for why the multiplier you calculated in part (b) is smaller (in absolute value) than the simple multiplier. Hint: you should be mentioning how the price level impacts AE and AD variables. Part (d): Determine the magnitude of the multiplier if government spending exogenously increases by $1. Part (e): Using 2 to 3 sentences, provide a theoretical explanation for why the multiplier you calculated in part (d) is smaller than the simple multiplier. Hint: you should be mentioning how the price level impacts AE and AD variables.
