Consider an economy of a nation that has the following aggregate expenditure. 1300- 1040- 780- 520- AE 260 Y = AE 260 390 520 650 780 9ło 1040 1170 1300 130 Real GDP Note: Please make sure your final answers are accurate to 2 decimal places. a) What is the value of the equilibrium national real GDP? Equilibrium = $0 b) What is the value of the multiplier? Multiplier = 0 c) If the autonomous consumption were to decrease by $520, what would be the new value of equilibrium real GDP? New equilibrium = S0 Aggregate expenditures
3. For the following problem, assume that the MPC, b, takes into account how much consumers spend as total income (Y) in the economy is changes. (Also: Hint GDP = Total Y) So we can rewrite our consumption function as : C= a +bY Assume: a= $2900 billion b=.75 GDP= $9,000 billion. A) What is C= B) What is S= C) If consumers were the only ones buying goods in the economy, would the economy have an excess supply of goods, excess demand of goods or would the economy be at equilibrium ?
1. Graphing the consumption function from the MPC Consider a hypothetical economy in which the marginal propensity to consume (MPC) is 0.50. That is, if disposable income increases by $1, consumption increases by 50¢. Suppose further that last year disposable income in the economy was $450 billion and consumption was $350 billion. On the following graph, use the blue line (circle symbol) to plot this economy's consumption function based on these data. CONSUMPTION (Billions of dollars) 700 600 500 400 300 200 100 0 -100 0 100 200 300 400 500 600 DISPOSABLE INCOME (Billions of dollars) 700 800 (?) From the preceding data, you know that the level of saving in the economy last year was $ economy is billion and the marginal propensity to save in this Suppose that this year, disposable income is projected to be $550 billion. Based on your analysis, you would expect consumption to be S billion and saving to be $ billion.
You are given the following data concerning Kadwan, a country located in the mountains. • Consumption function: C = 125 +0.50Y • Investment function: I = 125 • Aggregate expenditure function: AE =C+I • Equilibrium: AE = Y Describe the graph of the consumption function and the aggregate expenditure function and then identify the equilibrium level of income. The consumption function has an intercept of and a slope equal to MPC = =. The AE line is found by adding I to C. AE is achieved at Y = C with a slope equal to the MPC and an intercept of Equilibrium is steeper than parallel to flatter than
Using the table below to answer the following questions. Assume all values represent trillions of dollars. Construct a graph of the Aggregate planned expenditure What is the equilibrium expenditure? Explain what happens at a real GDP of $4 trillion dollars. (Note the aggregate expenditures and the effects on inventories) What are your total autonomous expenditures? What is the marginal propensity to consume? Ignoring imports and income taxes, what is the multiplier? If investment increases by $1.5 trillion, what is the change in real GDP?
4. Planned expenditure and income The following table shows consumption (C), investment spending (I), and government purchases (G), in a hypothetical economy for various levels of income. Also assume that there is an income tax rate of 25%, that base consumption is $100 billion, and that the MPC is 0.333, or 1/3. This economy is closed, with no international trade, therefore net exports are equal to zero and should not be considered. Use the given information to fill in disposable income, consumption, and planned expenditures in the following table. Income: Real Disposable (After Tax) Planned GDP Income C I, G Expenditures (Billions of (Billions of dollars) (Billions of (Billions of (Billions of (Billions of dollars) dollars) dollars) dollars) dollars) 100 50 150 100 50 150 200 50 150 300 50 150 400 50 150 500 50 150
