Explanation:
When the Central Bank of Wiknam increases the money supply, it is known as expansionary monetary policy.
When the Parliament of Wiknam passes a new investment tax credit, it is known as expansionary fiscal policy.
A shift in the aggregate demand curve to the right is when aggreagrate demand increases.
When money supply is increased, disposable income increases, consumption increases and aggregate demand increases.
Investment tax credit reduces the amount paid as tax and therefore increases disposable income, consumption increases and aggregate demand increases.
