Answer:
O institute an investment tax credit or increase the money supply
Step-by-step explanation:
When the demand curve shifts to the left, it means that demand has fallen. Stabilisation policy that would be carried out would be expansionary; money supply would be increased to stimulate demand.
Investment tax credit reduces the amount of tax owed and thus increases disposable income and increases demand.
Increasing money supply increases demand.
All things been equal, the demand curve should shift to the right.
