Before you begin
- Place events in chronological order
- Distinguish a historical document from a later account and from a student argument
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
How should you begin a depth-study argument?
What you will learn
- Define stagflation without equating inflation with a price level
- Calculate a percentage-point change using official unemployment data
- Assess the timing and costs of anti-inflation measures
Build a depth-study argument
- Write your own evidence-based answer before opening the model.
- Define the judgement, connect precise examples, consider counterarguments and explain the relative weight of the evidence. The original brief is a planning aid, not a historical source to quote as testimony.

The USA in the 1960s and 1970s is one theme within the American Paper 4 depth study in 2026. The official paper is 105 minutes and 60 marks, with two questions from the chosen depth study.

StudyForA enquiry brief · Stagflation, economic measures and policy costs
[1] Assess stagflation through defined measures, distributions and policy timing. The index example in this lesson is deliberately fictional, not a historical dataset.
1. Why does judging stagflation require more than one economic measure?
Compare after trying
Stagflation concerns the coexistence of price pressure and weak activity, so no single unemployment observation proves its entire definition. The rise from 4.9 per cent in 1973 to 8.5 per cent in 1975 establishes a labour-market deterioration of 3.6 percentage points, requiring separate price evidence.
Nominal income also differs from purchasing power. A common-scale income index must be compared with a price index, and national averages still leave variation between households. An illustration can explain that calculation without pretending to be measured historical experience.
Policy judgement needs equally careful chronology. Volcker’s appointment and operating change occurred in 1979, while major later costs and disinflation crossed into the 1980s. Decisions, implementation and outcomes must be separated before comparing the balance between price stability, employment and distribution.
Why this response fits
- Connects relevant, dated evidence with the judgement.
- Tests the explanation against contrasting groups, outcomes and limits.
What the term describes
Stagflation combines persistent inflation with weak economic activity and substantial unemployment. It does not require prices and output to rise at identical rates, and it does not mean every year of the 1960s and 1970s was the same. Inflation is the rate of increase in a price index, whereas the index records the level. A falling inflation rate can therefore coexist with prices continuing to rise, simply more slowly.
The BLS annual table records unemployment at 4.9 per cent in 1973 and 8.5 per cent in 1975 among the measured civilian labour force. The increase is 3.6 percentage points. Relative to the starting rate, it is approximately 73.5 per cent. Neither description means that 3.6 per cent of all Americans were the same people losing jobs. Annual averages also cannot identify each month’s rate or an individual worker’s experience.
Why evidence must be combined
An unemployment series alone cannot prove inflation; price evidence is also needed to establish the combination described by stagflation. Likewise, a national price index does not describe every household’s spending basket. Food, energy, housing, earnings and debt affected people differently. A careful judgement combines defined measures and dates instead of converting one national rate into a score for everybody’s living standards.
In an original fictional illustration, a money-income index rises from 100 to 120 while a price index rises from 100 to 150. Purchasing power becomes 120 divided by 150, multiplied by 100: eighty on the original scale, a fall of twenty per cent. The numbers illustrate the distinction between nominal and real change; they are not observations of an actual American household or a substitute for historical earnings data.
Policy and the period boundary
Ford’s voluntary anti-inflation appeal and later tax response faced competing objectives. Carter also confronted energy disruption and continuing inflation. Paul Volcker became Federal Reserve chair in August 1979, and October brought a change in operating procedures aimed at monetary restraint. The subsequent severe recession and much of the disinflation belong to the early 1980s, so they cannot be reported as outcomes completed by the end of 1979. Explain immediate decisions separately from later costs, recovery and competing evaluations of success.

Pause and explain
What do the 1973 and 1975 unemployment observations establish?
Worked example
How can money income rise while purchasing power falls?
Show the worked solution
- Compare income and price indices.
- Divide the income index by the price index.
- Interpret against the common starting scale.
Answer In the fictional 120 income / 150 price example, the real index is 80, so purchasing power falls 20% despite higher money income.

Test this topic →From guided practice to a new situation
Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Guided: Calculate the change from 4.9% to 8.5% and label both measures.
Give me a hint
Separate points and relative percentages.
Compare my reasoning
- Subtract 4.9 from 8.5.
- Divide the difference by 4.9.
- Multiply by 100 and interpret the denominator.
The annual unemployment rate rose by 8.5 − 4.9 = 3.6 percentage points. The relative increase is 3.6 ÷ 4.9 × 100 ≈ 73.5%. These measures concern labour-force rates, not the share of the whole population losing the same jobs or a direct measurement of inflation.
Look for these in your work
- Calculates both measures
- Preserves the labour-force scope
Independent: Calculate real change in the fictional income-index 120 and price-index 150 example.
Give me a hint
Both began at 100.
Compare my reasoning
- Divide 120 by 150.
- Multiply by 100.
- Compare with the starting value.
The real index is 120 ÷ 150 × 100 = 80. Relative to the original value of 100, purchasing power fell 20%. This labelled fictional illustration shows why higher money income does not guarantee real improvement; it is not a historical estimate for every American worker.
Look for these in your work
- Uses a common starting scale
- Labels the illustration and interpretation
Application: Correct a fictional 1979 timeline announcing the completed success of Volcker’s entire anti-inflation programme.
Give me a hint
Distinguish decision and later outcome.
Compare my reasoning
- Place the chairmanship and October change.
- Separate early-1980s developments.
- Identify prices and employment as outcome evidence.
The timeline can record Volcker’s August 1979 appointment and October operating change, but should leave later disinflation and recession on their actual early-1980s dates. An announcement does not establish completed success. Evaluation must compare the subsequent price and employment record rather than import later outcomes into 1979.
Look for these in your work
- Keeps the period boundary
- Requires evidence of outcomes
Common mistakes
- Using unemployment alone to prove inflation
- Confusing lower inflation with falling prices
- Reporting early-1980s outcomes as finished in 1979
What can you explain now?
What do the 1973 and 1975 unemployment observations establish?
Compare with the explanation
An annual labour-force rate rose by 3.6 percentage points; inflation needs separate evidence
The calculation is correctly labelled and does not claim the unemployment series directly measures prices.
