4. Study Questions and Problems #4 Real GDP (Y) and aggregate expenditures (AE) are shown for an economy in the first two columns of the following table. Suppose that economic forecasters predict government spending to increase in the near future from G=$1 trillion to G=$1.25 trillion. Recalculate the value of aggregate expenditures given the new value of G=$1.25 trillion. Enter those values to the second decimal place in the third column of the table.

The aggregate expenditures of the hypothetical country shown includes $2 billion in investment expenditures, $3 billion in government expenditures, and $1 billion in exports. At a real GDP of $18 billion, consumption expenditures less imports equal $12 billion and imports equal $2 billion. Use this information to graph the aggregate expenditures (AE) function. Assume autonomous consumption and autonomous imports are $0.
Given the following information about each economy, either calculate the missing variable or determine that it cannot be calculated: Instructions: Enter your answer as a whole number. If you are entering a negative number be sure to include a negative sign (-) in front of that number. a. Suppose C = $20.1 billion, 1 = $3.5 billion, G = $5.2 billion, and NX = $-1 billion.

illustrates and how it is related to the aggregate demand curve. 3. Figure 11.8 shows the aggregate expenditure curve when the price level is 110. When the price level rises to 120, the AE curve shifts vertically downwards from AE, by $1 trillion. When the price level falls to 100, the AE curve shifts vertically upwards from AE, by $1 trillion.

9. Deriving aggregate demand from the income-expenditure model The following graph shows three planned expenditure lines for an economy at three different price levels. PE120 corresponds to the price level of 120; PE100 corresponds to the price level of 100; PE140 corresponds to the price level of 140. The black line (which starts in the bottom left corner) is a 45-degree line illustrating the set of points for which real income and planned expenditure are equal. 800 PE, (P = 100) 700 PE, (P =120) 600 PE, (P =140) Slope: 0.5 500 Y-Intercept: 200 400 300 100 100 200 300 400 500 600 700 800 REAL INCOME (Billions of dollars) The level of equilibrium output at a price level of 100, is On the following graph, plot the aggregate demand curve that results from varying the price level from 100 to 120 to 140, holding all else equal. Hint: Real income and the quantity of output are equivalent. For example, a real income of $100 billion is the same as a quantity of output of $100 billion. PLANNED…
