Pearson Edexcel International GCSE in Economics (4EC1), specification Issue 3, February 2026. This topic covers spec sections 2.1.1–2.1.3 in full: the six macroeconomic objectives (rows a–f of 2.1.1), government policies (2.1.2a–d) and the trade-offs between objectives (2.1.3a). Worked numbers are original and re-derived below.

Must-know for this topic:

Economic growth 经济增长 (2.1.1a) is the increase in real GDP; it is measured by GDP increases, but GDP has LIMITATIONS (non-market activity, distribution, environmental damage, price differences). The economic cycle 经济周期 diagram shows BOOM (above trend), DOWNTURN, RECESSION (below trend, falling output) and RECOVERY. Each stage moves growth, inflation and unemployment together: a boom raises growth and inflation and cuts unemployment; a recession does the reverse. Growth's impacts: employment, living standards, poverty, productive potential, inflation (if demand outruns capacity) and the environment. Inflation 通货膨胀 (2.1.1b) is a sustained rise in the price level (deflation: a sustained fall), measured by the consumer price index 消费者价格指数 (CPI) — a weighted basket: weights 50/30/20 over goods with price relatives 110/100/120 give CPI $= 55 + 30 + 24 = 109$, so inflation is 9%. DEMAND-PULL inflation comes from AD shifting right (output AND prices rise); COST-PUSH from SRAS shifting left (prices rise, output falls). Interest rates and inflation move opposite: higher rates cut demand and inflation. Inflation hits prices, wages (real pay), exports (dearer), unemployment (if policy deflates), MENU COSTS, SHOE-LEATHER COSTS, uncertainty, confidence and investment. LOW UNEMPLOYMENT (2.1.1c) is measured by the ILO unemployment measure 国际劳工组织失业测量; its types are CYCLICAL, STRUCTURAL, SEASONAL, VOLUNTARY and FRICTIONAL; its impacts run through output, wasted resources, poverty, benefit spending, lost tax revenue, confidence and society. A CURRENT-ACCOUNT SURPLUS OR BALANCE (2.1.1d) means exports near imports in goods (visibles) and services (invisibles); deficits follow poor quality or dear domestic goods and an overvalued exchange rate; a deficit leaks demand abroad and can be inflationary. ENVIRONMENTAL PROTECTION (2.1.1e) targets visual, noise, air and water pollution — through taxation, subsidy, regulation, fines, pollution permits and public parks. REDISTRIBUTION (2.1.1f) attacks income inequality and absolute/relative poverty through progressive taxation, benefit payments, and education and healthcare investment.

Fiscal policy 财政政策 (2.1.2a) uses government revenue (DIRECT taxes on income, INDIRECT on spending) and expenditure; a FISCAL DEFICIT (spending above revenue) reflates but risks debt and crowding out; a SURPLUS deflates. Monetary policy 货币政策 (2.1.2b) is focused on INTEREST-RATE changes set by the central bank: higher rates raise borrowing costs, cutting consumption and investment (the transmission mechanism) and cooling inflation; the central bank may also use ASSET PURCHASES (quantitative easing) to add money when rates are near zero. Supply-side policy 供给侧政策 (2.1.2c) raises productivity and total output: privatisation, deregulation, education and training, regional policies, infrastructure spending, lower business taxes (to stimulate investment) and lower income taxes (to encourage work). GOVERNMENT CONTROLS (2.1.2d): regulation, legislation, fines and pollution permits — each with advantages (direct effect, flexibility) and disadvantages (enforcement cost, unintended consequences).

On the AD/AS model, a reflationary fiscal or monetary policy shifts AD from $P = 90 - Y/2$ up by 15: equilibrium moves from $(70, 55)$ to $(85, 62.5)$ — more output, higher prices; supply-side policy shifts SRAS right instead, raising output with LOWER prices.

The trade-offs (2.1.3a): UNEMPLOYMENT and INFLATION — deflating demand cuts inflation but costs jobs; GROWTH and INFLATION — fast growth overheats into demand-pull inflation; GROWTH and ENVIRONMENTAL PROTECTION — output raises pollution; INFLATION and the CURRENT ACCOUNT — dearer exports worsen the trade balance. Every policy answer should name the trade-off it accepts.

• Growth: definition, GDP measurement and its limitations; the cycle's four stages and each stage's effects; growth's six impacts (2.1.1a).
• Inflation and deflation definitions; CPI from the weighted basket (109 → 9%); demand-pull vs cost-push; the interest-rate link; the nine impact groups incl. menu and shoe-leather costs (2.1.1b).
• Unemployment: ILO measure, five types, seven impact groups (2.1.1c).
• Current account: visibles and invisibles; deficit/surplus causes; the exchange-rate link; deficit impacts (2.1.1d).
• Environment: four pollution types; six intervention measures (2.1.1e).
• Redistribution: inequality and poverty definitions; three reasons and three instruments (2.1.1f).
• Fiscal (direct/indirect, deficit/surplus), monetary (interest-rate mechanism, QE), supply-side (seven measures), controls (four, with pros and cons) (2.1.2a–d).
• The four trade-offs between objectives (2.1.3a).

Boundary notes: Paper 2 (macroeconomics, 80 marks, four 20-mark questions) rewards data-response calculation (the CPI arithmetic) and trade-off evaluation. All worked numbers are original.
