The verticаl аxis is lаbeled “Price Level,” and the hоrizоntal axis is labeled “Real Output.” The AS curve is drawn as a hоrizontal line at price level of 100. The AD curve slopes downward from left to right and intersects the AS curve at a price level of 100 and output of 1400. A second AD curve, labeled AD′, is positioned to the right of the original AD curve, also intersecting the AS curve at price level 100 and output of 1400. A dotted vertical line drops down from the AD curve at output 1000, and another dotted line drops from the AD′ curve at output 1400. The graph above shows the aggregate supply (AS) and aggregate demand (AD) curves for an economy. Calculate the spending multiplier if AD shifts to AD' as a result of an increase in government spending of $100. Show your work. Will a decrease in income taxes have to be larger, smaller, or equal to $100 in order to shift the AD by the same amount as the $100 increase in government spending? Explain. If the marginal propensity to save decreases, will the spending multiplier increase, decrease, or remain unchanged? Now assume instead that the AS curve is upward sloping. Would the change in real gross domestic product resulting from the $100 increase in government spending be greater than, less than, or equal to the change shown in the graph above? Now assume that wages and prices are perfectly flexible. As a result of $100 increase in government spending, will real GDP increase, decrease, or remain unchanged? Explain.
