Explain the relationship between the aggregate expenditures model in graph (A) below and the aggregate demand–aggregate supply model in graph (B) below. In other words, explain how points 1, 2, and 3 are related to points 1’, 2’, and 3’.
Explain in words and with graph, why rising prices reduce the multiplier effect of an autonomous increase in aggregate demand.

- The economy of Newland is in short-run macroeconomic equilibrium. The current real output is $400 billion, and the full employment output is $500 billion. The marginal propensity to consume is 0.8. (a) Is the economy experiencing a recessionary output gap or an inflationary output gap? Explain.

(i) Calculate the minimum change and indicate the direction of change in government spending required to shift the aggregate demand curve to close the output gap. Show your work. (ii) If instead Newland’s government changes income taxes without changing government spending, calculate the minimum change and indicate the direction of change in income taxes required to shift the aggregate demand curve to close the output gap.

In other words, real GDP demanded by different groups of buyers, i.e., Consumers (C), Businesses (I), Government (G), and Net Amount by Foreigners (Export - Import), at different price levels give us points on a graph, which are connected to form a curve called AD curve.
