The total expenditure schedule in Macroland begins with these initial levels (in billions of dollars): Income = 1,000; Consumption = 900; Investment = 200; Government = 300; Net Exports = −100. If the MPC = 0.75 and income increases in increments of 200, find the equilibrium level of income. If full employment requires an income level of 2,000, what (if anything) should the government do? Indicate both the direction of the spending change and the size of the spending change.
Due to an increase in consumer wealth, there is a $40 billion autonomous increase in consumer spending in the economies of Westlandia and Eastlandia. Assuming that the aggregate price level is constant, the interest rate is fixed in both countries, and there are no taxes and no foreign trade, complete the accompanying tables to show the various rounds of increased spending that will occur in both economies if the marginal propensity to consume is 0.5 in Westlandia and 0.75 in Eastlandia. What do your results indicate about the relationship between the size of the marginal propensity to consume and the multiplier?

Each economy is currently in equilibrium with real income and planned expenditure equal to $100 billion, as given by the black points (plus signs) on the following two graphs. Assume that both economies are closed to trade, and that neither economy has taxes that change with income. The graphs also plot the 45-degree line. The first economy has an MPC equal to 0.5. Therefore, its initial planned expenditure line has a slope of 0.5 and passes through the point (100, 100). The second economy has an MPC equal to 0.75. Therefore, its initial planned expenditure line has a slope of 0.75 and passes through the point (100, 100). Now, suppose there is an increase of $20 billion in planned investment in each economy. In the first economy (with MPC = 0.5), the $20 billion increase in planned investment causes equilibrium income to increase by billion. In the second…arrow_forward

- The following table shows consumption (C), investment spending (I), and government purchases (G), for some hypothetical economy at several levels of income (reported in billions of dollars of real GDP). Assume that in this economy, income is taxed at a rate of 25%, base consumption is $50 billion, and that the marginal propensity to consume (MPC) is 0.667, or 2/3. Further assume that this economy is closed, that is, there is no international trade and so net exports are always equal to zero. Use the given information to fill in disposable income, consumption, and planned expenditures in the following table.

That is, where aggregate output equals planned aggregate expenditure. Remember that planned aggregate expenditure in an economy with a government is AE = C +I+ G, so equilibrium is Y = C+I+ G. If output (Y) exceeds planned aggregate expenditure (C +I+G), there will be an unplanned increase in inventories. That means actual investment will exceed planned investment. Conversely, if C+I+G exceeds Y, there will be an unplanned decrease in inventories. Assume that MPS is 0.25 and autonomous consumption is 100 (autonomous consumption is defined as the expenditures that consumers must make even when they have no disposable income). Assume also that government spending (G) is 200 and the government is running a balanced budget. Assume also that planned investment (I) is 150. a) Write the consumption and saving functions (equations) b) Calculate the planned AE at any three levels of aggregate output (income) and unplanned inventory changes…arrow_forwardThe Greek letter αα represents a number that determines how much output responds to unexpected changes in the price level.

That is, when the actual price level exceeds the expected price level by 1, the quantity of output supplied will exceed the natural level of output by $4 billion. Suppose the natural level of output is $40 billion of real GDP and that people expect a price level of 110. On the following graph, use the purple line (diamond symbol) to plot this economy's long-run aggregate supply (LRAS) curve. Then use the orange line segments (square symbol) to plot the economy's short-run aggregate supply (AS) curve at each of the following price levels: 100, 105, 110, 115, and 120.arrow_forward
- You are given the following information about aggregate demand at the existing price level for an economy: (1) consumption = $500 billion, (2) investment = $50 billion, (3) government purchases = $100 billion, and (4) exports = $20 billion, imports = $40 billion. If the full-employment level of GDP for this economy is $700 billion. Marginal Propensity to Consume (MPC) of the economy is 0.5. How much government purchases would be closing the GDP-gap here? Explain your answer, and show your calculation.arrow_forwardAn economy is characterized by the following desired consumption and investment functions: C = 543 + 0.72Y and I = 752. Part (a): Calculate the equilibrium level of GDP and the multiplier for this economy. Round your answer for the multiplier to 3 decimal places. Example: 0.001 Part (b): Suppose the level of desired investment changed to I = 731, with no change to desired consumption. What is the new equilibrium GDP level for the economy? Part (c): Using 1 to 2 sentences, describe how this change to desired investment affects the AE function graphically. Part (d): Suppose the desired investment levels returns to I = 752, but now consumers spend 86 cents of every dollar earned. What is the new equilibrium GDP level for the economy? Part (e): Using 1 to 2 sentences, describe how this change to consumption habits affects the AE function graphically.arrow_forwardThe aggregate expenditures of the hypothetical country shown includes $2 billion in investment expenditures, $3 billion in government expenditures, and $1 billion in exports.
