The use of government income and expenditure instrument to regulate the economy is termed______

1. Analyze the question The question asks for the term used when government income (mainly taxation and other revenue) and expenditure (spending) are used as tools to regulate the economy.

2. Explain the concept

• Fiscal policy: the government's use of taxation, public spending, and borrowing to influence the economy. Its aims include controlling inflation, reducing unemployment, and promoting growth. Examples are raising or cutting taxes and increasing capital expenditure on roads and power.
• Monetary policy: the use of money supply, interest rates, and credit controls to regulate the economy. In Nigeria this is handled by the Central Bank of Nigeria (CBN), not by government revenue and spending.
• Physical policy: this is not a standard economic term. It is probably a distractor for "fiscal".
• Public finance: the study of how government raises and spends money. It is a field of study, not the use of those instruments to regulate the economy.

3. Solution

• The key phrases are "government income and expenditure" and "regulate the economy".
• Government income and expenditure are the tools of fiscal policy.
• Monetary policy uses money and interest rates, so A is out.
• B is not a real policy term.
• Public finance describes the area of study, not the act of regulating the economy, so D is out.

4. Answer The correct option is C. fiscal policy.

5. Tip Remember: Fiscal = Finances of the government (taxes and spending). Monetary = Money supply and interest rates (the CBN). When you see "taxation" or "government spending" in a question, think fiscal policy.
