In the economy of Keynesian Island, autonomous consumption expenditure is $50 million, and the marginal propensity to consume is 0.8. Investment is $160 million, government expenditure is $190 million, and net taxes are $250 million. Investment, government purchases, and taxes are constant—they do not vary with income. The island does not trade with the rest of the world. If the government increases its purchases by $200 million, what will be the change in the economy's equilibrium real GDP? Show the change on the graph as well.

Suppose you are given the following information. Autonomous spending is at $3000, government spending is at $4000, investment spending is at $2000, net exports are $1000, taxes are set at $3000 and the mpc is .8 or 80%. What is the equilibrium level of output? What would happen if the government tried to balance the budget? The other day, it was announced the consumer confidence was up last month. This sounded good news bells for firms. Why? What would be affected in our equation above? Why would it matter? Suppose the government tried to balance the budget my cutting spending, what would be the equilibrium level of output? If there is “crowding out (or in)”, what else might change in your equation? What impact would that have
Consider two closed economies that are identical except for their marginal propensity to consume (MPC). Each economy is currently in equilibrium with real GDP and total expenditure equal to $100 billion, as shown by the black points on the following two graphs. Neither economy has taxes that change with income. The grey lines show the 45-degree line on each graph. The first economy's MPC is 0.5. Therefore, its initial total expenditure line has a slope of 0.5 and passes through the point (100, 100). The second economy's MPC is 0.70. Therefore, its initial total expenditure line has a slope of 0.70 and passes through the point (100, 100). Now, suppose there is an increase of $30 billion in investment in each economy.

Then place a black point (plus symbol) on each graph showing the new level of equilibrium output. (Hint: You can see the slope and vertical…

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?
Consider the economy of Canada. Its households spend 55% of increases in their income and saves 45 %. There are no taxes and no foreign trade. Currently, Canada has a recessionary gap, the governments aim is to get actual output to increase by 220 billion dollars. How much of a tax cut do they need to have to achieve the overall increase in output of 220 billion dollars?

In a closed economy, the demand for the output consists of consumption (C), Investment (I), and government spending (G), i.e., D=C+I+G. The total income of all people in the economy is equal to GDP. At the same time, consumption depends on disposable income: C=Co+a*(GDP-T) where T is tax, 0
In an open economy with government, the marginal propensity to consume is 0.67, the tax rate is 0.2 and the marginal propensity to import is 0.35. Calculate the multiplier (to 2 decimal places).

According to Keynesian economics, what impact would a balanced budget amendment to the constitution requiring the federal government to balance its budget annually have on the economy?
In a Keynesian cross diagram, if the government decreases the tax rate, or makes the leakage of taxation less a) the aggregate expenditure function will shift to the left, but its slope will not change b) the aggregate expenditure function will shift to the right, but its slope will not change c) the slope of the aggregate expenditure function will increase and increases the point at which it crosses the 45 degree line where Aggregate Output is equal to Aggregate Expenditures d) the slope of the aggregate expenditure function will decrease
Although the United States is one of the richest nations in the world, it is also the world's largest debtor nation. We often hear that the problem is the nation's low savings rate. Suppose policymakers attempt to rectify this by encouraging greater savings in the economy. What effect will their successful attempts have on real GDP? Income-expenditure equilibrium will fall by several times the change in spending Planned investment spending will rise in the short-run The economy will expand Consumer spending will fall
