Document Summary

Ae is divided into 4 categories: desired consumption (c, desired investment (i, desired net. Aggregate expenditure = c + i, g and x are autonomous expenditures: do not change with national income. Co(cid:374)su(cid:373)ptio(cid:374) a(cid:374)d i(cid:374)(cid:272)o(cid:373)e are tied to i(cid:374)(cid:272)o(cid:373)e a(cid:374)d . C and im are induced expenditures: changes with changes in national income. C and i: no government, no foreign sector, ae = c + i. C is desired consumption: relationship between c and variables that influence it, c is influenced by disposable income. Disposable income: either consumed (c) or saved (s, income minus taxes. Real disposable income (yd: consumption is determined by real disposable income. C = a + byd: (cid:862)a(cid:863) is auto(cid:374)o(cid:373)ous consumption expenditure, (cid:862)(cid:271)(cid:863)yd is induced consumption expenditure. Example: c = 40 + 0. 8yd, b = 0. 8, if yd is 100, c = 40 + 0. 8(100, c = + = .

Consider a small open economy in which aggregate expenditures, AE, is the sum of consumption spending by households, investment spending by firms, government expenditures and net exports. You may assume that net exports are independent of real GDP and taxes are lumpâsum. The numbers in the table below are in billions.

Real GDP	Consumption	Investment	Gov't Expend.	Net Exports	Taxes	Aggregate Expenditures
1000	1430	120	50	-100	160	A
2000	B	120	50	-100	160	2250
3000	2930	120	50	-100	160	3000
4000	3680	120	50	-100	160	3750
5000	4430	120	50	-100	160	4500

a. (4 pts) For the table below, calculate the missing values, A and B. b. (2 pts) From the table above, what kind of situation is the country in with regards to the trade balance (i.e. do we have a trade surplus or deficit)? What kind of situation is the country in with regards to the domestic balance (i.e. is the government running a deficit or surplus)? c. (4 pts) Use the table above to calculate the slope of the AE curve. [Hint: Recall that the slope of the AE curve is the additional increase in aggregate expenditures arising from an increase in GDP.] d. (4 pts) Recall that the Aggregate Expenditure function is written as: AE = AE0 + (slope of AE) *Y where AE0 is Autonomous Expenditures. Use the table in part (a) and your answer to part (c) above to calculate Autonomous Expenditure AE0. [Hint: Calculate induced expenditures for any given level of GDP, and use your answer to figure out AE0] e. (2 pts) In the table above, what is the value of real GDP in equilibrium? f. (4 pts) Suppose that the government decides to spend 500 billion more. By calculating the multiplier (or any other way), calculate the value of the new equilibrium value of real GDP!
