Question

please answer 7,8,9,10. thank you so much!!:))

SECTION In the simple Keynesian model with an MPC equal Keynesian model with an MPC equal to 0.80, a S50 billion increase in investment spending leads to a maximum: $50 billion increase in equilibrium income. b. 580 billion increase in equilibrium income $250 billion increase in equilibrium income. d. $400 billion increase in equilibrium income S500 billion increase in equilibrium income. when $2.000 increase in income causes a $1,800 increase in consumption spending the marginal propensity to consume (MPC) is 0.9. b. the marginal propensity to save (MPS) is 0.20. c. the increase in saving is $200. d. All of the above are true e. Only a. and c. are true In the simple, two-sector model, if C = $120 billion +.75(Y) and I = S30 billion, then break-even disposable income (Yp - Y) is equal to: a. S120 billion. b. $250 billion. c. $480 billion. $600 billion 10. In the simple, two-sector model, if C-S120 billion+.75(Y) and I = $30 billion, then equilibrium income (Y) is equal to: $150 billion. $480 billion. $600 billion. d. $1,000 billion.

Answer 1

MPC = 0.80 SI = 50 Rise un incomez & billion Ay= L X I I-MPC мар ч -0. 02 = 1250 & billion rise (c) is correct. AY = 2000 & AC= 1800 & MPC = BC 1800 oog y 2000 MPS= I-MPC = -0.9= 0.10 Rise in soving = AY-AC= 2000 1800-2004 (a) and (c) are true (e) is correct option. - - C C = 120+0.75Y - I-304 billim. I YD=Y Brook even disposable income Soving - Y=Y0=0 C = 1204 0.75YD 0.25YD = 120 YD=14806 billion. (c) is corred. rium = Y = CtI= Rot u.n5y + 30 0. 25% = 150 Y = 150 (c) is correct. = [6oo & billion.
