Welcome to Fiscal Policy!
Ever wondered how the government decides to build new hospitals or why the amount of tax you pay changes? That is exactly what Fiscal Policy is all about. In this chapter, we’ll look at how the government uses its "wallet"—money coming in through taxes and money going out through spending—to influence the economy. Don't worry if it seems like a lot of numbers at first; we will break it down step-by-step!
1. The Government Budget
The Government Budget is simply a plan for a year. It lists how much money the government expects to receive (revenue) and how much it plans to spend (expenditure).
There are three possible states for the budget:
• Budget Surplus: When the government brings in more money than it spends. (Revenue > Spending)
• Budget Deficit: When the government spends more than it brings in. (Spending > Revenue)
• Balanced Budget: When spending and revenue are exactly the same.
Current vs. Capital Expenditure
Not all government spending is the same. Economists split it into two main types:
1. Current Expenditure: Day-to-day spending on recurring items. Think of this like a household's grocery bill. Examples: Paying teachers' salaries, buying medicine for hospitals, or electricity for streetlights.
2. Capital Expenditure: Spending on long-term assets that improve the country’s productive capacity. Think of this like a household buying a house or a new car. Examples: Building a new motorway, constructing a school, or investing in high-speed rail.
Key Takeaway: A budget is a balancing act between the money the government earns and the money it invests back into the country.
2. Taxation: How the Government Gets Money
Taxes are the primary source of income for the government. We can categorize them in a few ways:
Direct vs. Indirect Taxes
• Direct Taxes: These are taken directly from an individual's or a firm's income. You can't really avoid them if you earn money. Example: Income Tax or Corporation Tax.
• Indirect Taxes: These are placed on goods and services. You only pay them when you buy something. Example: Value Added Tax (VAT) or taxes on cigarettes and fuel.
Tax Structures
Governments can set up their tax systems in three different ways:
1. Progressive Tax: As your income rises, you pay a higher percentage in tax. This is designed to reduce inequality. (The rich pay a bigger "slice" of their pie).
2. Proportional Tax: Everyone pays the same percentage, regardless of how much they earn. (Everyone pays 20%, whether they earn £10,000 or £1,000,000).
3. Regressive Tax: As your income rises, you pay a smaller percentage in tax. While the dollar amount might be the same, it hurts lower-income people more. Example: A flat £5 tax on a cinema ticket is a bigger percentage of a poor person's income than a rich person's.
Calculating Tax Rates
You might be asked to calculate these two types of rates:
Average Tax Rate: The percentage of total income paid in tax.
\( \text{Average Tax Rate} = \frac{\text{Total Tax Paid}}{\text{Total Income}} \times 100 \)
Marginal Tax Rate: The tax rate paid on the next dollar or pound of income earned.
\( \text{Marginal Tax Rate} = \frac{\Delta \text{Tax Paid}}{\Delta \text{Total Income}} \times 100 \)
Quick Review: Remember, Progressive means Paying more as you get richer!
3. Fiscal Policy Tools: Discretionary vs. Automatic
How does the government actually change the economy? They use two methods:
Discretionary Fiscal Policy
This is when the government makes a deliberate choice to change taxes or spending.
Example: The government decides to lower Income Tax to encourage people to spend more during a recession.
Automatic Stabilisers
These are things that happen automatically without the government needing to pass new laws. They "dampen" the effects of the economic cycle.
• In a recession, more people lose jobs, so the government automatically pays out more in unemployment benefits. This keeps some money flowing in the economy.
• In a boom, people earn more and move into higher tax brackets, so the government automatically collects more tax, which helps prevent the economy from "overheating."
Key Takeaway: Automatic stabilisers are like the "suspension" on a car—they make the bumpy ride of the economy a bit smoother without the driver having to do anything!
4. Budget Positions and National Debt
It is important to distinguish between "deficit" and "debt."
• Budget Deficit: An annual shortfall (a flow).
• National Debt: The total amount the government owes from all previous years of borrowing (a stock).
Cyclical vs. Structural Deficits
• Cyclical Deficit: The part of the deficit that happens because the economy is in a downturn. When the economy improves, this deficit disappears.
• Structural Deficit: The part of the deficit that remains even when the economy is growing at its full potential. This is a sign that the government is spending more than it can afford long-term.
5. Advanced Concepts: The Laffer Curve and Crowding Out
The Laffer Curve
This theory suggests that if tax rates are too high, people will stop working hard or find ways to avoid taxes. Eventually, raising tax rates might actually decrease the total tax revenue the government receives.
Analogy: If a baker charges £50 for one loaf of bread, no one buys it, and the baker makes £0. If he charges £1, everyone buys it. There is a "sweet spot" in the middle where he makes the most money.
Crowding Out
This happens when the government borrows so much money to fund its spending that there isn't enough left for private businesses to borrow. This can lead to higher interest rates and less private investment.
Common Mistake: Don't confuse "crowding out" with just "spending too much." It specifically refers to the government's borrowing affecting the private sector's ability to invest.
6. Evaluating Fiscal Policy
Is Fiscal Policy always good? Not necessarily! When you write your exam answers, consider these "limitations":
• Time Lags: It takes time to realize there is a problem, time to pass a law, and time for the spending to actually hit the economy.
• Political Pressure: Politicians might cut taxes right before an election to get votes, even if it's bad for the economy (creating a structural deficit).
• The Multiplier Effect: One pound of government spending might lead to more than one pound of economic growth, but if the "multiplier" is small, the policy might be expensive and ineffective.
Did you know? John Maynard Keynes, a famous economist, argued that during a massive recession, the government should "spend its way out" by creating jobs, even if it meant running a large deficit!
Summary: The "Big Picture" Takeaways
• Fiscal Policy uses government spending and taxation to influence Aggregate Demand (AD).
• Expansionary Fiscal Policy (cutting taxes/raising spending) is used to fight unemployment and recession.
• Contractionary Fiscal Policy (raising taxes/cutting spending) is used to reduce inflation.
• Success depends on the balance between automatic stabilisers and discretionary choices, while keeping an eye on the National Debt.
