Why is understanding monetary and fiscal policy important in macroeconomics?

Understanding monetary and fiscal policy is crucial in macroeconomics because these policies directly affect overall economic stability and growth. Monetary policy, managed by a country’s central bank, involves controlling the money supply and interest rates to influence economic activity. For instance, lowering interest rates can stimulate borrowing and investment, which can boost economic growth. On the other hand, fiscal policy involves government spending and taxation decisions that can either stimulate the economy during downturns or cool it during expansions. Together, these policies help maintain economic stability by managing inflation, unemployment, and overall economic expansion.

This understanding allows economists and policymakers to respond appropriately during different phases of the economic cycle, ensuring that the economy remains healthy and resilient to shocks.
