AQA GCSE Economics: Interest Rates and Government Income and Expenditure — Revision Notes

Condensed for the final weeks. For the full explanation, use the Interest Rates and Government Income and Expenditure study guide.

Interest rate effects (3.2.1.1)

Interest rate	Consumers	Producers
Rises	Borrowing/spending discouraged (loans costlier); saving encouraged (better returns)	Borrowing/investment discouraged; holding cash relatively more attractive than expanding
Falls	Borrowing/spending encouraged; saving discouraged	Borrowing/investment encouraged

Keep consumer and producer effects separate — exam questions often ask about one specifically. Always state the direction (rise/fall) and a brief reason, not just “interest rates affect the economy.”

Factors influencing different rates: borrower risk (riskier borrower → higher rate), loan/savings term length, and the wider rate level set by the central bank.

Government income and expenditure (3.2.1.2)

Two separate classification axes — a frequently conflated pair:

Axis	Categories	What it describes
How collected	Direct vs. indirect	Direct = paid directly by the person/organisation levied (e.g. income tax). Indirect = collected by an intermediary and passed on, ultimately borne by the consumer via price (e.g. VAT)
Burden by income	Progressive vs. regressive	Progressive = larger % of income from higher earners. Regressive = larger % of income from lower earners

They combine independently — e.g. income tax is typically both direct and progressive; VAT on a good is typically indirect and (relative to income) regressive.

Worked example: interest calculation and behaviour

A student deposits £1,800 at 5% annual interest.

Interest = principal x rate = 1800 x 0.05 = £90 earned in year 1

If the rate RISES: saving becomes more attractive (better return),
so the student is more likely to save a larger proportion of
their income than before.

Pairing a numeric interest calculation with a behavioural explanation in one answer reflects how this content is typically assessed.

Worked example: classifying a tax on both axes

Classify a tax on cigarettes (a fixed amount added to the price of every packet, regardless of the buyer’s income) on both classification axes.

How collected:     the retailer collects the tax within the price
                    and passes it to government -- this is an
                    INDIRECT tax
Burden by income:   a fixed amount per packet takes a LARGER
                    percentage of a low earner's income than a
                    high earner's income (assuming similar smoking
                    habits) -- this makes it REGRESSIVE relative to
                    income, even though the tax itself doesn't vary

This example shows why indirect taxes are frequently (though not automatically) regressive – a fixed charge is a larger share of a smaller income – which is exactly the kind of reasoning link between the two classification axes that a strong exam answer makes explicit, rather than treating direct/indirect and progressive/regressive as two facts to memorise independently.

Government spending and revenue in outline

Main UK government revenue sources include income tax, National Insurance, VAT and corporation tax; main spending areas include health, education, welfare/pensions and defence. You are not expected to memorise exact current figures, but should be able to name several revenue sources and several spending areas, and recognise that changes to either (raising a tax, cutting a spending area) are themselves a form of government economic policy with winners and losers – the same trade-off style of reasoning tested elsewhere in this specification.

Key terms

Interest rate — cost of borrowing, or reward for saving, as a % per year. Direct tax — paid directly by the individual/organisation levied (income tax, corporation tax). Indirect tax — collected by an intermediary, passed to government, borne by the consumer via price (VAT). Progressive tax — % of income paid rises as income rises. Regressive tax — % of income paid falls as income rises.

Interest rates and government policy together

Interest rates and government taxation/spending are two different levers – monetary and fiscal – that can be used toward similar economic goals, which is worth stating explicitly if a question asks you to compare policy tools. A rise in interest rates and a rise in income tax both tend to reduce spending in the economy, but through different mechanisms (the cost of borrowing versus the amount of disposable income left after tax) and via different decision-makers (the central bank versus the government) – recognising this parallel, rather than treating interest rates and taxation as entirely unconnected topics, helps with exam questions that ask you to evaluate or compare approaches to managing the economy.

Common mistakes

• Describing an interest rate change’s effect without stating whether it’s a rise or fall.
• Confusing direct/indirect with progressive/regressive — these are two separate systems, not one.
• Applying interest rate effects identically to consumers and producers without noting investment is the producer-specific decision.
• Miscalculating simple interest by forgetting to convert a percentage to a decimal first.

Connecting to policy objectives

Government revenue and spending decisions here connect directly to the broader policy objectives (economic growth, price stability, employment, balance of payments) covered in 3.2.2 — taxation and spending are among the main tools government uses to influence those objectives, so this content is the “how government affects the economy” half of a pair with “what government is trying to achieve.”

Quick self-test

• State the effect of a fall in interest rates on consumer borrowing and on producer investment, with a reason for each.
• Distinguish direct from indirect taxation, and progressive from regressive, using income tax and VAT as examples.
• Calculate the interest earned on £2,400 saved at 4% for one year.
• Name two factors that influence why different loans offer different interest rates.
• Explain why income tax counts as both direct and progressive.
