The AS/AD model (every paper, Question One)

The same model as inflation — here, the mark is on identifying the shift AND its effect on real GDP (Y), not just the price level.

Reading it for growth

A rightward AD shift (more spending) OR a rightward AS shift (more production capacity) both raise Y — that IS economic growth.
Explain what caused EACH curve to shift, even when only one obviously moves — a paper often expects both AS and AD to shift from one event.
A supply-side shift (AS right) grows the economy WITHOUT raising the price level as much as a demand-side shift (AD right) does — say this when asked to compare two growth causes.

Exam-style A new battery-powered aircraft: short-term purchase cost, then long-term cheaper operation Explain the short-term and long-term impacts on AS/AD and on growth. SHORT-TERM: buying the aircraft is investment spending, but it initially just reallocates spending — it does not immediately raise AD. LONG-TERM: cheaper operating costs let the airline lower fares, raising consumer spending (AD shifts right) AND lowering a cost of production for the wider tourism sector (AS shifts right). Both shifts raise Y — real GDP grows — with a smaller rise in the price level than an AD-only shift would cause. ✓ Look for BOTH a demand-side and a supply-side effect in a single scenario — real papers often want both curves explained, not just one.

Comparing two growth-causing events for scale

Compare how MANY people/businesses each event affects, how PERMANENT the effect is, and how DIRECTLY it feeds spending or capacity across the whole economy.
