Answer:
Option C is correct - discretionary fiscal policy is less effective than is implied by the early Keynesian view.
Explanation:
When the economy is in recession, an increase in government expenditure is effective to increase the income but not to decrease the interest rate. During the recession, the economy is in a liquidity trap. At low levels of income, the interest rate is at a minimum and the LM curve is flat.
The increase in government expenditure leads to a rightward shift of the IS curve which increases the income. This is because the interest rate is at such a low level, that the increase in government investment could not crowd out the private investment.
Notwithstanding, the Keynesian and non-Keynesian economists agree that fiscal policy has its own constraints to increase the income during a recession.
The discretionary fiscal policy has a problem of increasing the level of income as it is a source of investment from private enterprise to public enterprise.
Thus, the discretionary fiscal policy is less effective than is implied by the early Keynesian view.
