Public finance is concerned with how governments fund activities and administer finances. It involves theories of public revenue (taxes), expenditures, and debt. The objectives of public finance include maintaining order, promoting justice and development. Its main functions are allocation of resources, distribution of income, economic stabilization, and economic growth. Allocation involves determining spending on public goods via the budget. Distribution aims to reduce inequality through taxes and programs for the poor. Stabilization uses fiscal policy to maintain employment and price stability. Growth focuses expenditures on infrastructure to promote higher production and economic expansion.
