This assignment examines the effects of a government income tax cut on the Australian economy. It analyzes how reduced taxes lead to increased disposable income, boosting consumption demand and shifting the Aggregate Demand curve. The potential inflationary pressures caused by this expansionary fiscal policy are then addressed by considering the Reserve Bank of Australia's (RBA) response through monetary policy. The RBA could raise the cash rate to curb inflation, leading to a contractionary effect on economic output and potentially offsetting some of the initial stimulus from the tax cut.
