The report then delves into macroeconomic analysis, exploring aggregate demand and aggregate supply to determine equilibrium levels of income and price. Furthermore, it investigates the role of government policy instruments, including fiscal and monetary policies, in maintaining economic stability.

The report concludes by discussing the policy framework and stabilization instruments employed by the Australian government to address economic fluctuations, including automatic and discretionary stabilizers.
