Consider an economy in which taxes, planned investment, government spending on goods and services, and net exports are autonomous, but consumption and planned investment change as the interest rate changes. You are given the following information concerning autonomous consumption, the marginal propensity to consume, planned investment, government purchases of goods and services, and net exports: Ca = 1,500 – 20r, c = 0.6; I= 2,450 – 60r; G= 1,980; NX=- 200; T= 1,750. a. Compute the value of the marginal propensity to save. b. Compute the amounts of autonomous planned spending, Ap, when the interest rate equals 0, 2, 4, and 6. c. Compute the equilibrium levels of income when the interest rate equals 0, 2, 4, and 6. Graph the IS curve.

Suppose a closed economy has an aggregate consumption function given by C = 50 + 0.50Yd and generates $2500 output and income in equilibrium. Suppose also that the government spends 400 and imposes a lump-sum tax of 100. What is the level of intended investment?
#12 ch. 13 Can you explain what the correct one is and why? Can you also explain why the other ones are incorrect?
The private consumption of Macroland is given by C=500+0.75Y and the private investment function is given by I=400−1000r, where r is the interest rate and Y is the GDP. The planned aggregate expenditure can therefore be written as PE=C+I=900+0.75Y−1000r. The equilibrium in the goods and services market happens when the planned expenditure is equal to the actual expenditure, or PE=Y Find the equilibrium GDP by solving the system of equations PE=900+0.75Y-1000r PE= Y for Y and PE. Note your solutions will depend on r! 1. Plot your solution for Y in a diagram measuring Y on the horizontal axis and r on the vertical axis. This curve is called the IS curve.

The economy is in equilibrium such that Planned Aggregate Expenditure (AE) = Aggregate Output (Y) = 1,200. We have earlier observed that when Y increased from 900 to 1,200 Aggregate Consumption (C) increased from 800 to 1000. If investments increase by 55, how much will Aggregate Income change from its current value of 1,200? 110 82.5 165 1,365 1,310

C= 26 +0.75Y = 60 X = 24 M = 10 (Advanced analysis) The equations give information for a private open economy. The letters Y, C, I, X, and M stand for GDP, consumption, gross investment, exports, and imports, respectively. Figures are in billions of dollars. The multiplier for the economy is 4.6. 3.33. 5.0. 4.0.

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
