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.
In the country of Arcadia, the minimum amount of consumption spending that will occur in a
given year is $50- that is, no matter what level of income households have, the aggregate
amount of consumption spending in the economy will be at least $50. In addition, for every extra
dollar of national income, consumption spending will increase by $0.75. (Note: For the entirety
of this problem, assume that Taxes = trans fers = 0, and the aggregate price level in Arcadia is
fixed.)
a. What is the marginal propensity to consume in Arcadia? [TYPE YOUR ANSWER BELOW]
b. Write out the consumption function for the Arcadian economy. [TYPE YOUR ANSWER

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?

After the price level rises to 110, however there is an upward movement along the aggregate demand curve, and real GDP declines to $14 trillion.

- Assume the current equilibrium level of income is $200 billion as compared to the full-employment income level of $240 billion and that consumption is the only component of aggregate expenditures that depends upon the level of GDP. If the MPC is 5/8, what change in aggregate expenditures is needed to achieve full employment?arrow_forwardYou 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?

Make a table showing the effect on I, C, and GDP for each of 3 rounds and the total effect after all possible rounds are completed if the MPC = 0.6 Use the table I present in my video lectures #1 and #2 as your guidefor format. Draw an AD/AS diagram showing the effect of the above on real GDP if we are far to the left of QN so the SRAS curve is flat. Be sure to include the numbers from the table on your diagram in their correct places. Start with AD0 and Q0, then show the effect of rounds 1 and 2 with AD1, Q1, AD2, and Q2. After you have done the first 2 rounds, skip ahead to showing the final AD curve and the final Q (ADF and QF). Remember to include the numerical distance covered from Q0 to QF on your diagram. I did this in video 2, so review that help you with this. Think carefully on whether the AD curve is shifting to the right or to the left. Remember, shifts to the right are increases and to the left are decreases.arrow_forward
- The rate of output and planned expenditures for the economy of Timbuktu are shown in the following table: Total Output Planned Aggregate Expenditures (Two-Sector Economy)(Real GDP in billion dollars) (in billions) 5,000 5,250 5,500 5,500 6,000 5,750 6,500 6,000 7,000…arrow_forwardAs you know equilibrium occurs where Y = AE. 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 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).

Further assume that this economy is closed, that is, there is no international trade and so net exports are always equal to zero.
