Question 52

In an open economy with government intervention, the marginal propensity to save is 0.15, the marginal propensity to tax is 0.10, and the marginal propensity to import is 0.25.

If there is an autonomous increase in private investment of £12 billion£12\text{ billion}£12 billion, what are the resulting value of the multiplier (kkk) and the final change in the equilibrium level of national income (ΔY\Delta YΔY) through the circular flow of income?

A

k=4.0k = 4.0k=4.0 and ΔY=+£48 billion\Delta Y = +£48\text{ billion}ΔY=+£48 billion

B

k=0.5k = 0.5k=0.5 and ΔY=+£6 billion\Delta Y = +£6\text{ billion}ΔY=+£6 billion

C

k=2.0k = 2.0k=2.0 and ΔY=+£24 billion\Delta Y = +£24\text{ billion}ΔY=+£24 billion

D

k=2.0k = 2.0k=2.0 and ΔY=+£6 billion\Delta Y = +£6\text{ billion}ΔY=+£6 billion
