The objective of public finance is to promote full employment, national income, and price stability. Public finance is concerned with how the government manages its revenue and expenditure to achieve economic stability and growth. The government's revenue comes from taxes, duties, fees, and other sources, and it is used to provide public goods and services, such as education, healthcare, infrastructure, and defense. The government's expenditure should be carefully planned and managed to achieve its economic objectives, including the promotion of full employment, the increase of national income, and the maintenance of price stability. By achieving these objectives, public finance can contribute to the overall economic well-being of the country.
