Both fiscal and monetary policies can be used to increase consumer and business spending and stimulate economic growth, but they operate through different mechanisms.

Fiscal policy involves the use of government spending and taxation to influence the economy. Expansionary fiscal policy aims to boost spending and aggregate demand by increasing government spending and/or reducing taxes. For instance, the government can invest in infrastructure projects, provide tax cuts, or increase social welfare programs. These measures directly inject money into the economy, encouraging consumer and business spending. However, implementing expansionary fiscal policy can impact the federal budget by increasing government deficits or reducing surpluses. Higher spending or tax cuts can lead to a deficit, while higher tax revenues or reduced spending can result in a surplus.

Monetary policy, on the other hand, is managed by the central bank (in the case of the United States, the Federal Reserve), and it focuses on manipulating interest rates and controlling the money supply. Expansionary monetary policy is often employed by central banks to stimulate spending and economic growth. This policy involves reducing interest rates, making borrowing cheaper for businesses and consumers. Lower interest rates encourage businesses to invest, consumers to borrow for purchases such as homes or cars, and can also decrease the cost of servicing existing debt. Increased spending and investment then lead to economic growth. However, the impact of monetary policy on the federal budget is indirect. Although the central bank's policy decisions affect government borrowing costs for new debt, they do not directly impact federal spending or revenue.

In summary, both fiscal and monetary policies can be utilized to increase consumer and business spending and spur economic growth. Fiscal policy relies on government spending and taxation measures that directly impact the federal budget. Monetary policy, managed by the central bank, focuses on interest rates and money supply to influence the economy and indirectly impacts the federal budget through government borrowing costs.
