Final answer:
Expansionary fiscal policy is the most appropriate economic policy combination to combat a recession.
Step-by-step explanation:
In response to a recession, the most appropriate economic policy combination would be expansionary fiscal policy. This involves increasing government spending or reducing taxes to boost aggregate demand and stimulate consumption and investment.
Expansionary fiscal policy can be illustrated using the aggregate demand and aggregate supply curves. By shifting the aggregate demand curve to the right, the economy can reach its potential GDP and full employment.
Examples of expansionary fiscal policy measures include direct increases in government spending on infrastructure projects or tax cuts that put more money in the hands of consumers and businesses.
