Macroeconomic Objectives - Part 2

Demand-pull and cost-push inflation are the two main types of inflation. They have different causes, different consequences, and require different policy responses. Understanding both is essential.

Demand-pull inflation (1 mark — definition).

Inflation caused by aggregate demand rising FASTER than the economy can produce. Too much demand chasing too few goods → firms raise prices.

Drivers of demand-pull (1 mark — application).

• Consumer credit boom (households borrow to spend).
• Government spending increases.
• Tax cuts boosting disposable income.
• Lower interest rates encouraging borrowing.
• Strong export demand.
• Population growth.

Example of demand-pull (1 mark — example).

UK 1980s — consumer credit boom, deregulated banking. Demand grew rapidly, inflation peaked at 9.5% in 1990.

Post-COVID 2021-2022 — pent-up consumer demand + stimulus + supply constraints. Inflation surged to 11.1% in 2022 (partly demand, partly cost).

Cost-push inflation (1 mark — definition).

Inflation caused by production COSTS rising. Firms pass costs through to consumers via higher prices.

Drivers of cost-push (1 mark — application).

• Oil/energy price rises.
• Wage increases (often via union pressure).
• Higher raw material costs (food, metals).
• Weak currency raising import prices.
• Higher indirect taxes (VAT, energy levies).
• Supply chain disruption.

Example of cost-push (1 mark — example).

1973 oil price shock — oil prices quadrupled; inflation spread through prices of transport, energy, manufactured goods.

UK 2022-2023 — Russian invasion of Ukraine doubled gas prices; food prices surged; UK inflation peaked at 11.1%. Cost-push dominant.

Comparison

	Demand-pull	Cost-push
Cause	Excess demand	Higher costs
Effect on output	Output rises	Output FALLS (stagflation)
Policy response	Tighten policy	Supply-side / accept
AD/AS shift	AD shifts RIGHT	AS shifts LEFT

Stagflation

A specific concern with cost-push: HIGHER prices AND LOWER output AND HIGHER unemployment. The combination is called stagflation. The 1970s saw severe stagflation; 2022 had stagflation elements.

Real-world distinction

Most inflation episodes have BOTH components. The 2022 UK peak was mainly cost-push but had some demand-pull (post-COVID rebound). Distinguishing the dominant cause guides policy.

Conclusion. Demand-pull inflation arises from excess demand; cost-push from rising costs. Demand-pull responds well to tighter monetary/fiscal policy; cost-push needs supply-side measures. Most inflation episodes mix both. Identifying the dominant cause is essential for the right policy response.

A current account deficit is a key indicator of a country's economic relationship with the rest of the world. Understanding its meaning, causes, and implications is essential to economic analysis.

What the current account is

The current account is one of three sections of the balance of payments. It records:

• Trade in goods: physical exports and imports (cars, food, machinery).
• Trade in services: financial services, tourism, professional services, education.
• Net income: profits, dividends, interest from foreign investments.
• Net transfers: foreign aid, gifts, remittances.

What a deficit means

A current account deficit means a country's PAYMENTS to the rest of the world EXCEED its RECEIPTS. The country is a NET BORROWER from the rest of the world.

UK example: UK runs a 3-5% of GDP current account deficit. Means UK imports more goods than it exports AND foreign investors earn more from UK investments than UK earns from foreign investments.

Causes of current account deficit

1. Loss of competitiveness.

If domestic goods become more expensive than foreign equivalents, exports fall and imports rise.

Drivers:

• High wage costs.
• Low productivity.
• Strong currency.
• Outdated technology.

Example: UK manufacturing's relative decline.

2. Strong domestic demand.

A consumer or government spending boom pulls in imports.

Example: UK pre-2008 — consumer credit boom raised imports significantly.

3. Decline of key industries.

Loss of competitive industries leaves the country unable to supply own demand.

Example: UK manufacturing share of GDP fell from 25% (1970) to 10% today.

4. Resource depletion.

Loss of exportable resources.

Example: UK North Sea oil declined; fewer net oil exports.

5. Strong currency.

A high pound makes exports expensive abroad, imports cheaper at home.

6. Globalisation.

Manufacturing moved to lower-wage countries; developed economies import goods.

7. Demographic factors.

Older populations consume more, save less — tend to run deficits.

8. Higher savings abroad.

Surplus countries (China, Germany, Japan) recycle savings into deficit countries' assets.

Effects of a current account deficit

Negative effects:

• Currency pressure. Persistent deficits can weaken currency.
• Borrowing rises. Country becomes more indebted to rest of world.
• Vulnerability. Sudden capital outflows can cause crisis.
• Reflects structural issues in competitiveness or industry.

Less concerning:

• If deficit funds INVESTMENT (productive use) rather than consumption.
• If foreign investors willingly fund the deficit.
• If country has strong institutions and credibility.

When deficits become a crisis

Deficits become problematic when:

• Funded by short-term borrowing (can be withdrawn).
• Country's debt is large and rising.
• Confidence in country falls.
• Currency falls sharply.

Examples of crisis:

• Asian financial crisis 1997 — deficits + short-term borrowing → currency collapse.
• Greek crisis 2010 — persistent deficits + lost market confidence.
• UK 1976 — IMF bailout after persistent deficit + lost confidence.

When deficits are sustainable

• US — runs large deficit (3-4% GDP) but dollar status and strong institutions sustain it.
• UK — 3-5% deficit; pound stable; foreign investment willing.
• Australia — persistent deficit funded by inward investment.

These countries have run deficits for decades without crisis.

Policy responses to deficit

1. Expenditure-reducing. Tighten policy to reduce demand and imports.

2. Expenditure-switching. Make imports more expensive / exports cheaper.

• Currency depreciation.
• Tariffs (controversial).

3. Supply-side. Improve productivity, education, infrastructure to make exports more competitive.

4. Long-run. Industrial policy to rebuild competitive industries.

Comparison: deficit countries vs surplus countries

• Deficit countries (UK, US, Australia): consume more than produce; borrow from abroad; need to maintain confidence.
• Surplus countries (Germany, Japan, China): save more than consume; lend abroad; vulnerable to losing export markets.

Both extremes can have problems. Modest balance is healthier.

Conclusion. A current account deficit means a country imports more (and earns less from foreigners) than it exports/earns. Causes include lost competitiveness, strong demand, industry decline, and structural factors. Effects depend on size, funding, and credibility: modest deficits funded by willing investment are sustainable; large deficits with short-term borrowing can cause crises. Policy responses include demand reduction, currency depreciation, and supply-side competitiveness measures. The UK has run persistent deficits without crisis but the underlying competitiveness issue remains.

High inflation has WIDELY differing effects across the economy. Some groups gain, others lose, and the distributional impact is often regressive. Understanding who wins and who loses is essential to evaluating policy responses.

Impact on households

Negative for most:

1. Real income falls. If wages don't keep up with inflation, real wages fall. UK 2022-2023 saw the largest real wage fall in decades.

2. Living standards decline. Households can afford less.

3. Particular hit to fixed-income groups. Pensioners on fixed pensions, low-wage workers, those on benefits.

4. Low-income households hit hardest. They spend higher share on essentials (food, energy, rent) — exactly what rose most in 2022 (food +20%, energy +50%+).

5. Confidence falls. Consumer spending may decline, slowing economy.

Positive for some:

1. Borrowers with fixed-rate mortgages see real debt value fall. 2. Asset owners (property, shares, gold) may gain.

Net effect on households

Average household loses; LOW-INCOME households lose most. Highly regressive distributional effect.

Impact on workers

Negative:

1. Real wages may fall if pay rises don't match inflation.

2. Wage demands rise but may not be met.

3. Job security may decline if firms struggle.

Positive:

1. Wage demands more successful in tight labour markets.

2. Workers in high-demand sectors may secure good rises (tech, healthcare).

Wage spiral concern

If workers consistently secure inflation-matching rises, costs rise, more inflation. This 'wage-price spiral' can be hard to break. UK 1970s example.

Impact on savers

Negative:

1. Real value of cash savings falls if interest rate < inflation.

2. Pensioners particularly affected — many on fixed incomes.

3. Bonds lose value as interest rates rise.

Positive:

1. Variable-rate accounts may benefit if rates rise.

2. Equity holdings may rise if firms can pass through costs.

Impact on firms

Negative:

1. Costs rise (energy, raw materials, wages).

2. Profit margins squeezed if can't fully pass costs to consumers.

3. Investment becomes harder to plan with uncertain prices.

4. Export competitiveness lost if UK inflation > foreign.

Positive for some:

1. Firms with pricing power can pass costs through and even gain.

2. Asset-heavy firms may gain (property, commodities).

Impact on government

Negative:

1. Public sector wages must keep up.

2. Benefits and pensions must rise (often by CPI).

3. Bond yields rise — borrowing costs increase.

4. Public confidence may fall in government's economic management.

Positive:

1. Tax revenue may rise (more nominal income → more tax).

2. Debt value falls in real terms (if not indexed).

Impact on the wider economy

Negative:

1. International competitiveness lost.

2. Investment decisions distorted.

3. Uncertainty rises.

4. Resource misallocation as price signals are confused.

Distributional analysis — winners and losers

Group	Winner or Loser
Fixed-income workers	LOSER
Pensioners (most)	LOSER
Low-income (high essentials share)	BIG LOSER
Borrowers (fixed-rate)	WINNER
Asset owners	WINNER
Firms with pricing power	WINNER
Cash savers	LOSER
Exporters (if currency falls)	WINNER
Importers	LOSER

Inflation is a TRANSFER from creditors to debtors, from fixed-income to flexible-income, and often from poor to rich.

Regressive impact on inequality

The 2022-2023 UK inflation spike was strongly REGRESSIVE:

• Energy and food prices rose most.
• These are essentials.
• Low-income households spend a higher share on essentials.
• So inflation hit them hardest.

UK Institute for Fiscal Studies found low-income households faced significantly higher effective inflation than wealthy households.

Policy responses

Different groups need different protections:

For low-income households:

• Targeted cost-of-living support.
• Energy bill subsidies.
• Real-terms increases in benefits.

For pensioners:

• Inflation-linked pension increases.
• Energy pension support.

For savers:

• Higher interest rates as monetary policy.
• Inflation-linked savings products.

For firms:

• Limited direct support; rely on supply-side measures.

Macroeconomic policy:

• Bank of England raises interest rates.
• Government may use fiscal restraint.

Justified judgement

High inflation has WIDELY DIVERGENT effects:

• Losers: fixed-income households, pensioners, savers, low-income workers.
• Winners: borrowers, asset owners, firms with pricing power.

The DISTRIBUTIONAL IMPACT is generally REGRESSIVE — those least able to cope are hit hardest. This creates political pressure for support and explains why central banks target low and stable inflation.

The UK 2022-2023 episode illustrates:

• Real wages fell.
• Low-income hit hardest.
• Bank raised rates aggressively.
• Government provided cost-of-living support.

Conclusion. High inflation affects different groups very differently. Fixed-income workers, pensioners, savers, and low-income households are the main losers; borrowers, asset owners, and firms with pricing power gain. The distributional impact is generally regressive — exactly the groups least able to cope are hit hardest. This is why central banks target low and stable inflation and why high-inflation periods (like UK 2022-2023) generate political pressure for government support. The lesson is that inflation is not just an aggregate problem — it's a distributional problem.

The UK's persistent current account deficit is a long-standing feature of the economy and a frequent subject of debate. The answer to whether it's a problem depends on: size, sustainability, source of funding, and what causes the deficit. The textbook answer is more nuanced than 'deficits are bad'.

What the deficit looks like

UK current account deficit:

• 2010s-2020s: typically 3-5% of GDP.
• Components: large goods deficit (£200bn/year); services surplus (£150bn/year); net income negative; small transfers.
• Persistent for 20+ years.

The textbook concern

Standard analysis identifies deficits as worrying because:

• Country borrows from abroad to fund consumption.
• Persistent deficits raise external debt.
• Vulnerable to capital outflows / sudden stops.
• Reflects loss of competitiveness.

But the textbook view is more nuanced than 'all deficits bad'.

When deficits ARE a problem

1. Funded by short-term borrowing. If foreigners lend short-term, they can pull funds quickly → currency crash.

Example: Asian financial crisis 1997 — short-term borrowing fled, currencies collapsed.

2. Country has low credibility. Emerging markets with weak institutions can face crises.

Example: Argentina, Turkey, various emerging-market crises.

3. Used for consumption, not investment. If deficit funds consumption (current goods) rather than investment (future productive capacity), country becomes poorer.

4. Linked to weak fundamentals.

• Falling productivity.
• Industrial decline.
• High inflation.
• Political instability.

5. Reflects fixed currency strain.

• Eurozone periphery 2010-2015 — couldn't devalue.

When deficits are NOT a serious problem

1. Funded by inward direct investment. Foreigners building factories, buying property → long-term, productive funding.

UK example: significant FDI flows fund much of UK deficit.

2. Country has strong credibility.

• Stable institutions.
• Low inflation.
• Strong rule of law.

3. Country has reserve currency status.

• US dollar dominance allows US persistent deficits.
• Other countries hold dollars; finance US deficit indirectly.

4. Deficit funds investment. If foreign borrowing builds productive capacity, country grows out of debt.

5. Modest size. Deficits below ~5% of GDP usually manageable.

The UK's specific case

UK deficit is NOT in crisis territory because:

1. Pound is stable. No sudden capital flight.

2. Foreign investment willing. UK attracts significant FDI.

3. Strong institutions. Rule of law, stable government, credible central bank.

4. Reserve currency status of sterling (modest but real).

5. Diversified economy. Services strength offsets goods weakness.

6. London as global financial centre. Attracts capital.

Reasons for concern

But the UK deficit reflects some underlying issues:

1. Manufacturing decline. UK no longer competitive in many traded goods.

2. Low productivity growth. Especially since 2008.

3. Reliance on financial services. Less diversified than ideal.

4. Vulnerability post-Brexit. Loss of EU market access in some areas.

5. Possible currency pressure if confidence falls.

6. External debt rising. UK's foreign debt now substantial.

Comparison with other countries

US: runs persistent ~4% deficit; not in crisis (dollar dominance).

UK: persistent 3-5% deficit; not in crisis (foreign investment).

Germany: runs ~6% SURPLUS; reflects strong exports + low consumption.

Greece: ran ~10% deficit pre-2010; collapsed in eurozone crisis.

China: historically large surplus; reducing.

The lesson: SIZE matters, but CONTEXT matters more.

Policy options if intervention judged necessary

1. Expenditure-reducing. Tighten fiscal/monetary policy.

• Reduces demand → fewer imports.
• Costs: lower growth, higher unemployment.

2. Expenditure-switching.

• Currency depreciation (weaker pound → exports cheaper).
• Trade restrictions (tariffs, quotas) — provokes retaliation.

3. Supply-side / competitiveness.

• Productivity investment.
• Skills training.
• Infrastructure.
• R&D investment.
• Industrial policy.

These take time but address root causes.

4. Inward investment promotion.

• Tax incentives.
• Stable business environment.
• Foreign investor support.

5. Encourage export sectors.

• Export credit support.
• Trade promotion.
• Specific industrial policies (semiconductors, clean energy).

Costs of intervention

Any intervention has costs:

• Currency depreciation raises import prices (inflation).
• Trade restrictions reduce overall efficiency.
• Industrial policy can be captured by special interests.
• Demand reduction causes unemployment.

The 'do nothing' option

Some economists argue:

• Modest persistent deficits are normal.
• Markets will adjust currency over time.
• Aggressive intervention may cause more harm than good.

Justified judgement

For the UK at 4% deficit, the answer is:

NOT A CRISIS because:

• Funded by willing foreign investment.
• Pound stable.
• Strong institutions.
• Long-run history of similar deficits.

BUT WORTH ADDRESSING because:

• Reflects structural issues (manufacturing decline, productivity).
• Cumulative effect on external debt.
• Vulnerability if confidence shifts.
• Indicates broader economic weakness.

APPROPRIATE RESPONSE:

1. Don't panic. Don't make crisis-style responses to non-crisis.

2. Supply-side focus. Address root causes — productivity, manufacturing, exports.

3. Long-term thinking. Investment in skills, infrastructure, R&D.

4. Monitor sustainability. Watch FDI flows, debt levels, currency.

5. Maintain credibility. Stable institutions, sound policy, no sudden moves.

6. Avoid protectionism. Tariffs damage more than they help.

The UK approach should be: GRADUAL improvement of competitiveness rather than dramatic intervention. Get manufacturing right; get productivity right; get skills right. Over time, this addresses the deficit while not creating new problems.

Conclusion. The UK's 4% current account deficit is NOT a serious crisis but IS worth addressing. It reflects long-run structural weaknesses in manufacturing and productivity rather than imminent danger. Aggressive intervention (currency intervention, trade restrictions, severe demand reduction) would likely cause more harm than the problem warrants. SUPPLY-SIDE MEASURES (productivity, skills, R&D, industrial policy) addressing root causes are the right approach. The deficit will likely persist for years; the question is whether the UK gradually closes it through improving competitiveness. The current account is a SYMPTOM, not the disease — treating the symptom directly is less wise than treating the underlying competitiveness issues.

Deeper insight: This question illustrates a broader point about current account analysis. The textbook focus on the deficit itself (a measurement) misses the real question: WHAT does the deficit indicate about the economy? A deficit funded by productive investment is healthy; one funded by short-term consumption borrowing is dangerous. The UK case is in between — manageable but indicative of structural weakness. Modern policy should focus on the UNDERLYING competitiveness questions, not just headline deficit numbers. This is why most economists don't see UK deficit as a crisis but DO see UK productivity stagnation as a serious problem.
