Question 1

What is a recession, and who decides when one has started?

Accepted Answer

A **recession** is a significant, widespread and sustained decline in economic activity — and the widely quoted definition is a rule of thumb rather than the real one.

**The common shorthand: two consecutive quarters of falling GDP.** This is the **technical recession** definition, used widely in the UK and Europe because it is simple, timely and unambiguous.

**Why economists dislike it as a definition:**

**It can miss real recessions** and flag false ones. A single bad quarter followed by a flat one, or a statistical revision, can flip the answer.

**GDP data is revised**, sometimes substantially. Countries have been declared in and out of recession retrospectively.

**It ignores everything else** — employment, incomes, output, spending — which is what a recession actually consists of.

**The more considered approach.** In the United States, the **NBER Business Cycle Dating Committee** determines recession dates, using a broader set of indicators and explicitly requiring **depth, diffusion and duration**. They deliberately announce **late**, after the data has settled — sometimes a year or more after a recession began — because being right matters more than being fast. The 2020 recession was dated as extremely deep but only two months long, which the two-quarter rule would have handled poorly.

**The UK has no equivalent official committee**, so the two-quarter rule dominates public discussion by default, with the ONS publishing the underlying data.

**Related terms:**

**Depression** — no agreed definition, but reserved for something far deeper and longer. The 1930s is the reference point.

**Stagflation** — stagnant growth with high inflation, difficult because the usual policy responses to each work against the other.

**Soft landing** — inflation brought down without triggering a recession.

**A growth recession** — growth positive but too weak to keep unemployment stable.

**Why the label matters less than it seems.** Whether a downturn is technically a recession changes nothing about anyone's circumstances, but it moves markets, shapes policy and dominates coverage — which is why arguments about the definition get more attention than the underlying data.

Accepted Answer

A check of whether you could still afford the mortgage if interest rates were considerably higher than they are now — applied in addition to, and separately from, whether you can afford the payment

Question 5

How does compound interest actually work?

Accepted Answer

Compound interest is interest earned on interest already earned. Simple interest pays only on the original sum; compound interest pays on the original sum plus everything accumulated so far, so the

Question 6

How is inflation actually measured?

Accepted Answer

By pricing a fixed basket of goods and services repeatedly and tracking how much it costs over time. The apparent simplicity hides a series of judgement calls, each of which materially affects the

Question 7

What actually happens to your money when you deposit it in a bank?

Accepted Answer

It stops being your money in the physical sense and becomes a debt the bank owes you. Your balance is an entry in the bank's ledger recording what it must repay on demand — not a box of your notes
