Final answer:
A tax increase on consumer income is a correct fiscal policy change to address the inflationary potential of the economy.
Step-by-step explanation:
In a Keynesian framework, a tax increase on consumer income is a correct fiscal policy change to address the inflationary potential of the economy. This is because a tax increase on consumer income will cause consumption to fall, pushing the Aggregate Demand (AD) curve to the left, which can help reduce inflationary pressures.
