Answer: There is no fiscal policy action that can keep the inflation and unemployment stable.
Step-by-step explanation:
If there is a negative real shock such as an oil crisis, it will be hard fir the affected economy to adjust and be stable.
A negative real shock will lead to a reduction in growth and a rise in inflation. Even in cases whereby there is an increase in the money supply, this will lead to a rise in real growth but the result will be that there will be an higher inflation
Therefore, there is no fiscal policy action that can keep the inflation and unemployment stable.
