Welcome to Fiscal Policy!
In this chapter, we are going to look at how the government uses its "wallet" to influence the economy. Just like you might adjust your spending if you're saving for a new phone, governments adjust their spending and tax collection to keep the country’s economy healthy. This is a core part of Macroeconomic Policy.
By the end of these notes, you’ll understand how the government tries to balance the books and why their decisions affect everything from the price of your snacks to how easy it is to find a job.
1. What is Fiscal Policy?
Fiscal Policy involves the manipulation of government spending (G), taxation (T), and the budget balance to influence the economy.
Think of it as the government’s two-handed control system:
• Hand 1: Spending. Money going out for schools, hospitals, and roads.
• Hand 2: Taxation. Money coming in from individuals and businesses.
Analogy: Imagine the economy is a car. Fiscal policy is like the accelerator and the brake. If the car is going too slow (recession), the government hits the gas (more spending/less tax). If it’s going too fast and overheating (high inflation), they hit the brakes (less spending/more tax).
Macro vs. Micro Functions
Fiscal policy does two things at once:
1. Macroeconomic function: It manages the "big picture," like total Aggregate Demand (AD), economic growth, and unemployment.
2. Microeconomic function: It affects specific markets. For example, a tax on cigarettes (demerit good) is a fiscal move designed to reduce smoking.
Quick Review: Fiscal policy is about G (spending) and T (taxation).
2. The Tools: Taxes
The government collects money through different types of taxes. It’s important to know the difference because they affect people’s "disposable income" differently.
Direct vs. Indirect Taxes
Direct Taxes: These are taken "directly" from an individual or a company’s income or wealth.
Example: Income Tax (taken from your paycheck) or Corporation Tax (taken from business profits).
Indirect Taxes: These are taxes on spending. They are added to the price of goods and services.
Example: VAT (Value Added Tax) or duties on petrol.
The Three "P"s of Tax Systems
1. Progressive Taxes: As you earn more, the percentage of tax you pay increases. This is often used to achieve an equitable distribution of income (making things fairer).
2. Proportional Taxes: Everyone pays the same percentage of their income, regardless of how much they earn. (Also called a "flat tax").
3. Regressive Taxes: As you earn more, the percentage of your income spent on the tax actually falls. Indirect taxes like VAT are often regressive because a £1 tax on a chocolate bar is a much bigger "chunk" of a poor person's income than a rich person's.
Key Takeaway: Governments use progressive taxes to reduce inequality by taking a larger proportion from those who can afford it most.
3. Influencing the Economy (AD and AS)
Fiscal policy is a "demand-side" policy, but it can also help the "supply-side."
Shifting Aggregate Demand (AD)
Recall our formula for Aggregate Demand:
\( AD = C + I + G + (X - M) \)
Expansionary Fiscal Policy: Used to boost the economy during a recession. The government increases G or decreases T. Lower taxes mean consumers have more money to spend (C) and firms have more profit to invest (I). This shifts the AD curve to the right.
Contractionary Fiscal Policy: Used to slow down inflation. The government decreases G or increases T. This reduces the money circulating, shifting the AD curve to the left.
Shifting Aggregate Supply (AS)
Fiscal policy can also help the supply side. For example, if the government spends money on education and training, it creates a more skilled workforce. This increases the productive potential of the economy, shifting the Long-Run Aggregate Supply (LRAS) curve to the right.
Did you know? Tax changes designed to "incentivise" people—like cutting income tax so people want to work more hours—are also considered supply-side fiscal moves!
4. The Budget Balance and National Debt
The "Budget Balance" is just the difference between what the government spends and what it receives in taxes.
1. Budget Deficit: When Government Spending > Taxation Revenue (\( G > T \)). The government is spending more than it earns and must borrow the difference.
2. Budget Surplus: When Taxation Revenue > Government Spending (\( T > G \)). The government has extra money left over.
3. Balanced Budget: When \( G = T \).
The National Debt
Don’t confuse the deficit with the debt!
• The Deficit is a "flow" (how much we overspend in one year).
• The National Debt is a "stock" (the total amount of money the government owes from all the years of borrowing combined).
Memory Aid: Think of a bathtub. The water flowing from the tap is the deficit. The total amount of water sitting in the bath is the national debt.
5. Cyclical vs. Structural Influences
Why does a budget go into deficit? It usually happens for two reasons:
Cyclical Influence: This happens because of the economic cycle. In a recession, the government automatically collects less tax (because people are losing jobs and spending less) and spends more on unemployment benefits. This "cyclical deficit" isn't a choice; it just happens because the economy is weak.
Structural Influence: This is a deliberate choice by the government, regardless of how the economy is doing. If a government decides to build 500 new schools, that’s a structural change to the budget balance.
Don't worry if this seems tricky! Just remember: Cyclical = caused by the economy's "ups and downs." Structural = caused by the government's "plans and rules."
6. Summary: What should you remember?
• Definition: Fiscal policy = Government Spending (G) + Taxation (T).
• Expansionary: Increase G, Decrease T (to grow the economy).
• Contractionary: Decrease G, Increase T (to stop inflation).
• Taxes: Can be Direct/Indirect and Progressive/Proportional/Regressive.
• Budget: A deficit happens when \( G > T \); the National Debt is the total of all borrowing.
• Objectives: Governments use fiscal policy to achieve low unemployment, price stability (low inflation), and economic growth.
Quick Review Box:
- G up / T down = Expansionary (AD shifts Right)
- G down / T up = Contractionary (AD shifts Left)
- National Debt = Sum of all past deficits.
Common Mistake to Avoid: Many students think the government always wants a budget surplus. Actually, during a recession, a government might deliberately run a deficit to jumpstart the economy!
