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

- 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?The desired aggregate expenditure function of an economy is illustrated in the graph to the right. The dashed line, Y*, shows the potential level of national income in this economy. The marginal propensity to spend is 0.75. Use the point drawing tool to plot and label the equilibrium level of income. Carefully follow the instructions above, and only draw the required object.

- 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.

Same information as in the previous question: The following are exogenous (not directly affected by income): G = 11 I = 4 X = M = 0 The consumption function is: C = k + cY, where k = 3, c = 0.8 Imagine the maximum potential output or real GDP of this economy is 100. Assume that is the same as saying we reach the edge of the PPF at 100. Now assume we want to get that economy from the current level of GDP to its maximum potential of 100.
