The use of income and expenditure instruments or policies to control or regulate the economic activities of a country is known as Fiscal Policy. Fiscal policy involves the use of government spending and taxation to influence the economy's performance. For example, during a recession, the government may increase its spending to stimulate economic growth and create jobs. Alternatively, during a period of high inflation, the government may reduce its spending and increase taxes to reduce the amount of money in circulation and lower inflation. Fiscal policy can be used to achieve various economic objectives, such as stabilizing the economy, promoting economic growth, and reducing income inequality. It is an essential tool for governments to manage the economy and ensure its stability and growth over the long term.
