Mark 1.00 out of 1.00
Suppose government expenditure in South Africa is R10 billion while autonomous consumption and investment spending are R25 billion
and R50 billion respectively. Autonomous exports are R100 billion and autonomous imports are R35 billion. Also, c = 0,85; t = 0,275 and m =
0,125. What is the equilibrium level of income in the economy? (Hint: at each step of your calculations, round off to 2 decimal places)
a. R167.5 billion

Use a Keynesian model to calculate the answer.
Dashboard / Courses / UNISA / 2023 / Semester 1 / ECS1601-23-S1 / Online assessments / Assessment 3
Full employment output = R80 million
Investment = R20 million
Autonomous consumption = R15 million
The marginal propensity to consume = 0,6.
The value of aggregate autonomous spending is
Answer:
35 million
Question 3
Correct
Mark 1.00 out of 1.00
Suppose that the economy is open and has a public sector. In the Keynesian model, we can say that …
a. a fall in autonomous consumption will raise the multiplier and decrease aggregate expenditure
b. an increase in the tax rate will increase the multiplier and raise aggregate expenditure
c. a fall in the marginal propensity of imports will raise the multiplier and aggregate expenditure will rise
d. a fall in autonomous imports will raise the multiplier and aggregate expenditure will rise.
The factors that impact the multiplier are discussed in section 7.3. of the prescribed textbook
