8. The income-expenditure model Consider a small economy that is closed to trade, so its net exports are equal to zero. Suppose that the economy has the following consumption function, where C is consumption, Y is real GDP, I is investment, G is government purchases, and T stands for net taxes: C = 50+0.5 x (Y-T) Suppose G = $255 billion, I = $50 billion, and T = $10 billion. Given the consumption function and the fact that for a closed economy total expenditure can be calculated as Y = C + I + G, the equilibrium output level is equal to $ billion. Suppose the government purchases are reduced by $150 billion. The new equilibrium level of output will be equal to Based on the effect of the change in government purchases on equilibrium output, you can tell that this economy's spending multiplier is equal to

8. The income-expenditure model Consider a small economy that is closed to trade, so its net exports are equal to zero. Suppose that the economy has the following consumption function, where C is consumption, Y is real GDP, I is investment, G is government purchases, and T stands for net taxes: C = 15+0.75 x (Y-T) Suppose G = $90 billion, 1 = $60 billion, and T = $20 billion. Given the consumption function and the fact that for a closed economy total expenditure can be calculated as Y=C+I+G, the equilibrium output level is equal to 5 billion. Suppose the government purchases are increased by $50 billion. The new equilibrium level of output will be equal to Based on the effect of the change in government purchases on equilibrium output, you can tell that this economy's spending multiplier is equal to
52)Consider the following consumption function: C = 800 + 0.75 YD for the fictitious economy of Zapland. If the government increases taxes by $200 million, what is the change in GDP? Assume that there is no increase in the price level. Select one: a. -$800 million b. $600 million c. $800 million d. -$600 million e. -$300 million
4. In the economy of St. Maynard Island, autonomous consumption expenditure is $185 million, and the marginal propensity to consume is 0.75. Investment is $150 million, government expenditure is $100 million, and net taxes are $80 million. Investment, government expenditure, and taxes are constant - they do not vary with income. The island does not trade with the rest of the world. a) What is the consumption function? b) What is the aggregate expenditure function? c) What is the island's autonomous aggregate expenditure? d) What is the size of the multiplier in St. Maynard Island's economy? e) What is the island's aggregate planned expenditure and what is happening to inventories when real GDP is $1,100 million? f) What is the economy's equilibrium aggregate expenditure?
2. How does income of the rest of the world (e.g., income of foreign countries) affect our domestic output? Explain in not more than 5 sentences. Hint: How does income of foreigners affect our net exports (NX)?
2. Public consumption of a country (two sectors) is indicated by the function C = 60 + 0.4Y. Calculate:a. Find the saving function.b. If the investment that occurs is 300, determine the balance national income.c. What is the consumption of the people of the country if the national income is 400.d. How much is the savings of the people of the country if the national income is 400.e. Make a graphical sketch of the consumption and saving functions in one image. Please solve subparts d,e thank u
1.a Suppose the country of Freelandia has an MPC of .85 and a real GDP of $200 billion. If its investment spending decreases by $3 billion, what will be its new level of real GDP?
. Suppose the United States economy is repre- sented by the following equations: Z = C + I + G, C = 500 + 0.75YD, T = 600, I = 300, YD = Y − T , G = 2000 Given the above variables, calculate the equilibrium level of output. assume that government spending decreases from 2000 to 1900. What is the new equilibrium level of output? How much does income change as a result of this event? What is the multiplier for this economy?
7. Marginal propensity to import and net exports The following graph shows net exports for a hypothetical country. U 50 50 40 20 20 NET EXPORTS (Billions of dollars) 10 10 -10 20 -20 300 400 ⑦? 500 600 700 REAL GDP (Billions of dollars) 0 100 200 13 and According to the graph, when the country is producing a real GDP of $400 billion, exports are function is equal to the than imports. The slope of the net exports and thus tells you that for every $1 increase in real GDP, do not change (because they are assumed to be autonomous with respect to real GDP). by
3. Suppose an economy had aggregate demand components with the following relationships: Consumption Spending, C-140 +0.60*(DY) Investment Spending, I-25 +0.15"Y Government Spending, G-0 Net Export Spending, X=0 Tax Collections, Tx = 0 a. What is the equilibrium income for this economy (Show your work)? b. If the Government decided to Increase G spending by 6, what would be the new equilibrium income for this economy (Show your work)? Page 2 bed tooing c. If instead the Government decided to Reduce Tx (taxes) by 10 (i.e., send checks to people), what would be the new equilibrium income for this economy (Show your work)? d. If instead the Government decided to Increase G spending and Increase Tx (taxes) by 20, what would be the new equilibrium income for this economy (Show your work)?
The cost of rebuilding the Philippines after typhoon Haiyan could reach USD 5.8bn”, a senior official has said. Assume the government of Australia Department of Foreign Affairs and Trade provided a grant of USD 5.8 billion. Also assume that despite the hardships the Philippine families experienced, 15% was the beneficiary savings from the Australian grant. Further, assume all other factors remain constant.a. Calculate the total effect of the spending multiplier of the Australian government grant on the Philippine economy GDP growth. b. Examine the overall multiplier effect of the USD5.8 billion grant on the Philippine economy. Answer asap n correctly with proper typed explanation
42)Consider the following consumption function: C = 800 + 0.75 YD for the fictitious economy of Zapland.

3. Let C stand for consumption spending, I for investment, G for government purchases, X for exports, IM for imports, DI for disposable income, and NT for net taxes Consider the following identity C+I+G+ (X – IM) = DI + NT Which of the following best characterizes the above identity? a) National income must equal domestic product b) National income must equal the total amount of leakages from the nation's flow of income and expenditures c) Domestic product must equal the total amount of injections into the nation's flow of income and expenditures. d) Domestic product must equal the total amount of leakages from the nation's flow of income and expenditures.
