5. Algebra of 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 7 is for net taxes: C 40+0.5x (Y-T) Suppose G $265 billion, / $50 billion, and 7 $10 billion. Given the consumption function and the fact that, in a closed economy, total expenditure can be calculated as Y = C+I+G, the equilibrium output level is s billion. Suppose the government purchases are reduced by $100 billion. The new equilibrium level of output will be equal to s billion. 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 dlosed 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, 1 is investment, G is government purchases, and T stands for net taxes: C - 40 + 0.5 x (Y-T) Suppose G- $315 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+1+G, the equilibrium output level is equal to s billion. Suppose the government purchases are reduced by $200 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
2. Consider an economy where aggregate demand AD consists of aggregate con- 1000 and government = sumption C 10+ 0.8Y, aggregate investment I spending G = 800. (a) = (c) (d) What is aggregate demand if aggregate income/output is 10,000? Why is the economy not in equilibrium in that state? Calculate the goods market equilibrium for this economy. (b) Assume that the government increases spending by 20%. Calculate the new goods market equilibrium. What is the multiplier for the change in government spending? Assume now that the country starts trading globally and has Exports and Imports. Assume that imports are given by Im = n Y, with n being the marginal propensity to import. (e) Explain why - with exports and imports - a increase in government spending (e.g., 20%) results in a smaller change in aggregate demand/income in equilibrium than without exports and imports. (You do not have to calculate the new equilibrium.)
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
Only typed answer Explain why the multiplier falls when taxes depend on income. .1 Assume the following for the economy of a country: a. Consumption function: C = 60 + 0.75Yd b. Investment: I = 75 c. Government spending: G = 45 d. Net taxes: T = - 25 + 0.2Y e. Disposable income: Yd. = Y - T f. Equilibrium: Y = C + I + G Solve for equilibrium income. How much does the government collect in net taxes when the economy is in equilibrium? What is the government’s budget deficit or surplus?
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.

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
