Japan

2009 → -0.3% inflation rate long term → 0–1% inflation rate

interest rate → -0.1% (BoJ) government debt → ~260% of GDP (highest in the world) GDP growth (long term) → ~0–1%

Japan has experienced persistent low inflation of around 0–1% despite interest rates as low as -0.1% and government debt exceeding 260% of GDP, suggesting a liquidity trap where monetary policy is ineffective in stimulating aggregate demand.

• consumer expectations（预期通缩 → 推迟消费）
• weak animal spirits（投资信心低）
• monetary policy ineffective

• Keynesian persistent deflationary gap
• AD decrease → deflation（support）
• liquidity trap / policy failure
• long-run stagnation

USA (1970s Oil Crisis)

1973–74 → oil price: $3 →$12 (~4× increase) 1980 → inflation rate: 13.5% 1975 → unemployment: ~9%

GDP growth → negative during recession

During the 1970s oil crisis, US inflation reached approximately 13.5% while unemployment rose to around 9%, demonstrating stagflation caused by a sharp increase in oil prices, which shifted SRAS to the left.

• cost-push inflation
• SRAS shifts left
• stagflation（inflation + unemployment）

India

GDP per capita -> $2,500 –$3,000 GNI per capita -> $2,400 –$2,800

GDP growth → ~6–7% annually (2010s–2020s) extreme poverty → ~10% population (World Bank) Gini coefficient → ~0.35–0.37

large informal sector (~80–90% employment)

India has achieved strong GDP growth of around 6–7% annually, yet approximately 10% of its population remains in extreme poverty, indicating that national income statistics may not accurately reflect living standards.

• income inequality
• uneven distribution of income
• informal economy not captured

• GDP/GNI not good indicator of living standards

COVID-19 (Global + USA)

2020 → global GDP: -3.1% (IMF) 2020 → US unemployment: 14.7% (peak) 2022 → US inflation: 9.1% (peak)

massive fiscal stimulus → trillions (US stimulus packages)

During COVID-19, global GDP fell by 3.1% while US inflation later rose to 9.1% in 2022, showing that supply chain disruptions shifted SRAS left, causing inflation despite a fall in aggregate demand.

• AD decreases (lockdowns, reduced consumption)
• SRAS decreases (supply chain disruption)
• mixed shock（demand + supply）

Uses at

• AD decrease not always deflationary
• AD/AS simultaneous shift
• policy evaluation
• inflation + recession analysis

🇳🇴 Norway

GDP per capita → $90,000 –$110,000 GNI per capita → $85,000 –$100,000 HDI → 0.96（全球前列） sovereign wealth fund(the fund that government owns for government spending) → > $1.4 trillion

income inequality → very low（Gini ~0.27）

Norway’s high GNI/GDP per capita of over $90,000 is accompanied by strong social welfare, low inequality, and a high HDI, suggesting that national income can be a good indicator of living standards when income is evenly distributed and supported by effective institutions.

• strong redistribution
• public services（healthcare, education）
• sustainable wealth management

Uses at

• GNI/GDP IS a good indicator（argument）
• evaluation（depends on distribution）
• development success case

🇿🇦 South Africa（extremely high inequality）

GDP per capita → $6,000 –$7,000 GNI per capita → $6,000 Gini coefficient → ~0.67（one of the highest worldwide） unemployment → ~30%

South Africa has a relatively moderate GDP/GNI per capita, yet a Gini coefficient of around 0.67 and unemployment of approximately 30%, indicating extreme inequality and suggesting that average income figures do not reflect the actual living standards of most citizens.

• inequality
• unemployment
• unequal access to services

• GNI/GDP NOT good indicator（强力反例）

🇩🇪 Germany（non-inflation growth）

inflation → ~1–2% (pre-2020 stable period) GDP growth → positive steady growth unemployment → ~3–5%

Germany has experienced steady economic growth with low inflation of around 1–2%, suggesting that increases in aggregate demand are not necessarily inflationary when spare capacity exists and productivity improves.

• productivity growth
• supply-side improvement
• stable institutions

• AD increase NOT always inflationary（counter）
• Keynesian spare capacity

🇺🇸 USA (Post-COVID Recovery)

GDP growth → strong rebound (~5–6% in 2021) inflation → ~9.1% (2022 peak) unemployment → fell from 14.7% → ~3.5%

The US experienced strong post-COVID growth alongside inflation peaking at 9.1%, suggesting that rapid increases in aggregate demand can lead to inflation when the economy approaches full capacity.

• demand-pull inflation
• closing output gap
• overheating economy

Uses at

• AD increase → inflation（支持）
• near full employment case
• evaluation

🇺🇸 USA（Post-2008 Recovery → return to full employment）

2009 → GDP growth: -2.6% 2009 → unemployment: ~10%

2019 → unemployment: ~3.5% 2017–2019 → steady GDP growth (~2–3%) inflation → remained moderate (~2%)

Following the 2008 financial crisis, the US economy recovered from high unemployment of around 10% in 2009 to approximately 3.5% by 2019, suggesting that the economy gradually returned to its full employment level of output over time.

• flexible labour market
• recovery supported by expansionary monetary policy (low interest rates, QE, and higher government spending)
• increased aggregate demand over time
• relatively stable inflation

• economies return to full employment（support）
• long-run adjustment
• AD recovery
