   • Banks (e.g., commercial, investment, and central banks)
   • Insurance companies
   • Pension funds
   • Credit unions
   • Asset management firms
2. Financial Markets

   • Stock markets (e.g., NYSE, NASDAQ)

3. Financial Instruments
   Tools used to transfer resources or manage risk, such as:
   • Stocks
   • Bonds

   • Federal Reserve (U.S.)
   • Securities and Exchange Commission (SEC)
   • International Monetary Fund (IMF)
5. Participants
   The individuals or entities involved, including:
   • Retail customers

3. Liquidity Provision
   Ensures availability of liquid assets to meet short-term needs.
4. Price Discovery
   Determines the price of financial instruments through market interactions.

Public finance

Public finance is a branch of economics that focuses on the management of resources by governments and other public entities. It examines how governments generate revenue, allocate resources, and manage expenditures to influence the economy and achieve societal objectives.

Core Components of Public Finance:

1. Government Revenue This includes all sources of income for the government, primarily:
   • Taxes: Income tax, corporate tax, sales tax, property tax, excise duties, etc.
   • Non-Tax Revenue: Fees, fines, dividends from state-owned enterprises, royalties, etc.
   • Borrowing: Issuance of government bonds, loans from international institutions, or other states.
2. Government Expenditure Spending by the government to provide goods, services, and welfare programs. Major categories include:
   • Capital Expenditure: Investments in infrastructure, schools, hospitals, etc.
   • Revenue Expenditure: Day-to-day operational costs, such as salaries, subsidies, and debt servicing.
   • Transfer Payments: Welfare benefits, unemployment allowances, and pensions.
3. Public Debt The borrowing by the government to finance deficits when expenditure exceeds revenue. It includes:
   • Domestic Debt: Borrowed from within the country.
   • External Debt: Borrowed from foreign entities or international organizations.
4. Fiscal Policy The use of government revenue collection (taxation) and expenditure to influence the economy. Key types include:
   • Expansionary Fiscal Policy: Increases spending or reduces taxes to stimulate growth.
   • Contractionary Fiscal Policy: Reduces spending or increases taxes to curb inflation.
5. Public Budget An annual financial statement that outlines the government’s revenue and expenditure plans. Key components:
   • Surplus Budget: Revenue exceeds expenditure.
   • Deficit Budget: Expenditure exceeds revenue.
   • Balanced Budget: Revenue equals expenditure.
6. Public Goods and Services Goods and services provided by the government for public use, often funded through taxation, such as:
   • National defense
   • Law enforcement
   • Public health and education
7. Intergovernmental Fiscal Relations The financial interactions between different levels of government (e.g., federal, state, local) regarding revenue sharing, grants, and responsibilities.

Objectives of Public Finance:

1. Economic Stability: Managing inflation, unemployment, and economic growth.
2. Resource Allocation: Ensuring efficient use of resources for public benefit.
3. Income Redistribution: Reducing income inequality through progressive taxation and social welfare.
4. Public Welfare: Providing essential services and infrastructure for societal well-being.

Challenges in Public Finance:

• Deficit Management: Controlling excessive borrowing and public debt.
• Tax Evasion and Avoidance: Ensuring compliance with tax laws.
• Sustainability: Balancing short-term needs with long-term fiscal health.
• Economic Inequality: Addressing disparities through fiscal measures.
