Fiscal Policy — Taxation, Public Expenditure, and Budget Deficit
Learning Objectives
By the end of this section, you should be able to:
- Define fiscal policy and explain how governments use it to influence macroeconomic outcomes
- Distinguish between the three main tools of fiscal policy: taxation, public expenditure, and deficit financing
- Analyse how changes in tax policy affect individual behaviour, business decisions, and overall economic growth
- Evaluate the trade-offs involved in public spending decisions, including the multiplier effect and opportunity costs
- Interpret budget deficit data expressed as a percentage of GDP and relate it to a country's debt position
- Compare India's fiscal framework (FRBM Act, GST, Union Budget) with the US approach (TCJA, CARES Act, national debt)
- Apply fiscal policy reasoning to explain government responses to events like recessions, pandemics, and wars
Quick Answer
Fiscal policy refers to the deliberate use of government revenue collection (taxation) and spending (public expenditure) to influence a nation's economy. When an economy slows down, a government may cut taxes or increase spending — called expansionary fiscal policy — to stimulate demand. When the economy overheats, it may do the opposite. If the government spends more than it collects, it runs a budget deficit, which is financed by borrowing. India, the US, and most modern economies use fiscal policy as a primary lever alongside monetary policy to manage growth, inflation, and employment.
