Suppose that C = 100+ 0.75(Y -100), I= 50, G = 30, and X- M = 100, all in billions of dollars. What is the simple spending multiplier? What is real GDP demanded? What would happen to real GDP demanded if government purchases increased to $40 billion?

True or False. If spending exceeds output, real GDP will decline as firms cut back on production.

If total GDP for this economy is $17.04 trillion for the year shown in the table below, what was the total amount of government spending? Round your answer to the nearest hundredth. Components of GDP on the Demand Side (in trillions of dollars) trillion Consumption Investment Government spending Exports Imports Provide your answer below: Total GDP 11.61 3.11 ? 2.71 2.84 17.04

Consider a hypothetical closed economy in which households spend $0.75 of each additional dollar they earn and save the remaining $0.25. The marginal propensity to consume (MPC) for this economy is and the spending multiplier for this economy is Suppose the government in this economy decides to decrease government purchases by $250 billion. The decrease in government purchases will lead to a decrease in income, generating an initial change in consumption equal to This decreases income yet again, causing a second change in consumption equal to . The total change in demand resulting from the initial change in government spending is The following graph shows the aggregate demand curve (AD₁) for this economy before the change in government spending. Use the green line (triangle symbol) to plot the new aggregate demand curve (AD₂) after the spending multiplier effect takes place. Hint: Be sure that the new aggregate demand curve (AD 2) is parallel to the initial aggregate demand curve…

Suppose that the economy is depicted by the following relationship: where: C=$100 +0.75 (Y-T) G= $ 600 T = $ 600 1= $200 X = $ 50 Expenditures =C+I+G+X The economy is in equilibrium at a level of real GDP or income of $ Now suppose that the government decides to increase government spending by $50. What is the new equilibrium level of GDP or income? $(Round your answer to the nearest dollar) (Round your answer to the nearest dollar)

Explain graphically the determination of equilibrium GDP for a private economy through the aggregate expenditures model. Now add government purchases (any amount you choose) to your graph, showing its impact on equilibrium GDP. Finally, add taxation (any amount of lump-sum tax that you choose) to your graph and show its effect on equilibrium GDP. Looking at your graph, determine whether equilibrium GDP has increased, decreased, or stayed the same given the sizes of the government purchases and taxes that you selected.

Real Planned Government Net Aggregate Investment Purchases Exports Expenditures Consumption GDP $2,000 $1,600 $250 $250 $100 2,500 2,000 250 250 100 3,000 2,400 250 250 100 3,500 2,800 250 250 100 If potential GDP is $4,000 billion, how much should government spending increase so that the economy can move to the full employment level of GDP? (Hint: multiplier effect) $100 $300 $200 $400

In the country of Krugman, a business spent $100 million building a factory. GDP eventually increased by 200 million. People spend 11% of every dollar on imports. What is the marginal propensity to consume in this economy? Write your answer as a number, between 0 and 1. If you think the answer is 0, write 0.00, not 0. Answer: Study the graph below. When will the multiplier be biggest? Select one: The multiplier will be the same size no matter what Aggregate Demand is b. The multiplier will be one no matter what aggregate demand is When aggregate demand is at AD1 d. When aggregate demand is at AD3 e When aggregate demand is at AD2 Price Level AD₁ AS e All of these are true AD₂ AD₁ GDP Why is potential output called potential, when it is not actually the most the economy can produce? Select one: a. Because potential is the most the economy can produce right now, with the technology and workers and equipment we have right now. Ob. Because economists just like to be confusing for no reason…

Suppose real GDP is currently $12.5 trillion and potential real GDP is $13 trillion. If the president and Congress increased government purchases by $500 billion, what would be the result on the economy?
