Government and the macroeconomy

• Instrument decides the family. Deficit is a flow, debt is a stock. Regressive is about the percentage. Supply-side is about capacity. Growth is real. The rate divides by the labour force. Falling inflation is still inflation. Diagnose before you prescribe.
• Spending and taxes are fiscal. Interest rate, money supply and exchange rate are monetary. Anything aimed at what the economy can produce rather than what it spends is supply-side. Note that a cut in income tax appears in two of those rows — as fiscal policy when it is used to raise demand, and as supply-side policy when it is used to raise the incentive to work. The purpose decides which.
• Seven measures, three targets: better people (education and training, incentives to work), better capital and places (infrastructure, incentives to invest), better-working markets (labour market reform, deregulation, privatisation). Grouping them this way makes all seven recallable under pressure.
• Growth and recession share one set of causes: total demand, quantity of resources, quality of resources. Learn them once, then change the sign. Consequences always run through the same four groups, in the syllabus's own order: consumers, workers, producers/firms, government.
• Short and searching → frictional. Same months every year → seasonal. Whole economy, with a recession → cyclical. One industry or region, lasting years, with unfilled vacancies elsewhere → structural. Demand-side policy reaches only the third.
• Inflation and unemployment rising together → cost-push, so demand-side policy will not reach it. Inflation rising with unemployment low → demand-pull, so raise the interest rate and accept the cost in jobs. A negative rate → deflation; a smaller positive rate → disinflation.
• Four formulas, four denominators, and the denominator is where these calculations go wrong. Budget balance: revenue minus spending, then divide by GDP. Growth: divide by last year's real GDP. Unemployment: divide by the labour force. Inflation: divide by last year's index. Write the denominator down before the numerator and you will not mix them up.
• Review beats rereading, and spacing beats cramming. The single highest-return five minutes in this chapter is writing the interest-rate chain in both directions from a blank page, because it is the chain most questions in Topic 4 are built from.

• 4.1.1 — I can name all six macroeconomic aims, give the criterion a government typically sets for each, explain why each is wanted, and explain the three conflicts the syllabus names: full employment against stable prices, growth against environmental sustainability, and full employment against balance of payments stability.
• 4.2.1 — I can define the government budget, a budget deficit and a budget surplus, calculate the size of a deficit or surplus from revenue and spending figures, and express it as a percentage of GDP.
• 4.2.2 — I can name the main areas of government spending, give the reason for each and state its effects.
• 4.2.3 — I can give all six reasons for taxation, define progressive, regressive, proportional, direct and indirect taxes with examples, and explain the impact of taxation on consumers, workers, producers/firms, the government and the economy.
• 4.2.4 — I can define fiscal policy in one sentence that names both instruments and the target.
• 4.2.5 — I can describe expansionary and contractionary fiscal policy as changes in taxation and in government spending.
• 4.2.6 — I can explain the effect of fiscal policy on each macroeconomic aim, as a chain, with its limitations.
• 4.3.1 — I can define the money supply and monetary policy, and say who normally operates monetary policy.
• 4.3.2 — I can describe the three monetary policy measures — the interest rate, the money supply and the foreign exchange rate — in both the loosening and the tightening direction.
• 4.3.3 — I can write the interest-rate transmission chain in full, in both directions, and explain the effect of monetary policy on each aim with its limitations.
• 4.4.1 — I can define supply-side policy in terms of productive capacity rather than demand.
• 4.4.2 — I can describe all seven supply-side measures: education and training, infrastructure spending, labour market reforms, lower direct taxes, deregulation, improving incentives to work and invest, and privatisation.
• 4.4.3 — I can explain the effect of supply-side measures on each aim, and explain why they are the only policies that can raise growth and ease inflation at the same time.
• 4.5.1 — I can define economic growth.
• 4.5.2 — I can explain how growth is measured by real GDP, distinguish real from nominal GDP, and calculate a growth rate.
• 4.5.3 — I can give the three causes of growth the syllabus names and state the advantages and disadvantages of growth.
• 4.5.4 — I can define a recession, give its three causes, and give its consequences for consumers, workers, producers/firms and the government.
• 4.5.5 — I can describe the range of policies used to promote growth and discuss their effectiveness.
• 4.6.1 — I can define employment, unemployment and full employment, and say who is in the labour force and who is not.
• 4.6.2 — I can describe the labour force survey and calculate the unemployment rate using the correct denominator.
• 4.6.3 — I can describe frictional, structural, cyclical and seasonal unemployment with an example of each.
• 4.6.4 — I can give the consequences of unemployment for the individual, producers/firms, the government and the economy.
• 4.6.5 — I can match each type of unemployment to the policy that reduces it and discuss how effective that policy is.
• 4.7.1 — I can define inflation and deflation, and explain why a falling inflation rate is neither.
• 4.7.2 — I can describe how the Consumer Prices Index is constructed from a basket, weights and a base year, and calculate an inflation rate from index numbers.
• 4.7.3 — I can explain demand-pull and cost-push inflation and identify which is which from a description.
• 4.7.4 — I can explain the consequences of inflation for savers, lenders and borrowers, and for consumers, workers, producers/firms and the economy.
• 4.7.5 — I can describe the range of policies used to control inflation and discuss their effectiveness against each cause.

The two causes leave different fingerprints in the data. Demand-pull inflation arrives with low unemployment, strong growth and an economy running hot. Cost-push inflation can arrive with rising unemployment and falling output, because it is a cost shock rather than a spending boom. So when a data-response question gives you inflation and unemployment rising together, the cause is almost certainly cost-push — and that single observation decides the policy answer for the rest of the question.

• “The government cut interest rates to reduce the deficit, so that is fiscal policy.” Fix The instrument, not the purpose, separates fiscal from monetary. Taxation and government spending are fiscal. The interest rate, the money supply and the exchange rate are monetary, and they are normally operated by the central bank. Separating fiscal from supply-side is a different question, settled by what the measure is aimed at rather than by the instrument — see section 4.4. Name the family wrongly and the chain that follows, however good, is answering about something else.
• “A budget deficit means the country is in debt by that amount.” Fix The deficit is one year's shortfall, a flow. The national debt is the accumulated stock of past borrowing. A government can halve its deficit and still add to its national debt, because any deficit at all is a further addition to the stock.
• “A regressive tax is one where the rich pay less.” Fix The classification is about the percentage of income taken, not the amount paid. A \(\$500\) licence fee takes 5% of a \(\$10{,}000\) income and 0.5% of a \(\$100{,}000\) income. The rich person pays the same money and a far smaller share, which is exactly what makes the tax regressive.
• “Supply-side policy raises total demand and so raises output.” Fix Supply-side policy raises productive capacity: what the economy is able to produce. Some measures, such as a cut in income tax, also raise demand as a side effect, but the defining purpose is capacity. This is the distinction that makes supply-side policy the only family that can raise growth and ease inflation together.
• “GDP went up, so the economy grew.” Fix Growth is measured by real GDP. A rise in nominal GDP can be nothing but higher prices: if nominal GDP rises 8% while prices rise 8%, the quantity of output has not changed at all. Write “real” every time you write GDP in an answer about growth.
• “The unemployment rate is the unemployed as a percentage of the population.” Fix The denominator is the labour force: the employed plus the unemployed. Students, retired people and those caring for family are in the population but not in the labour force, so including them makes the rate far too low. Of the four calculations in this topic, this is the one where the wrong denominator is easiest to reach for.
• “Inflation fell from 6% to 2%, so prices fell.” Fix Prices still rose, just more slowly. That is disinflation. Deflation is a sustained fall in the general price level, which shows as a negative inflation rate or a falling price index. Reading a falling rate as falling prices misreads almost every data-response table in this topic.
• “Raise total demand and unemployment falls.” Fix Only cyclical unemployment responds to higher total demand. A miner whose pit has closed is structurally unemployed: extra demand does not give them the skills the new jobs need. Diagnose the type, then prescribe. The same rule governs inflation: demand-side policy cures demand-pull inflation and does very little about cost-push.
• “The survey counts everyone who is out of work.” Fix It counts only those actively seeking work. Discouraged workers who have stopped looking are excluded, so the measure understates the waste of labour, and it understates it most in the deepest recessions.
• “A part-time worker who wants full-time work is half unemployed.” Fix They are counted as fully employed. Under-employment of this kind does not appear in the rate at all, which is another reason the figure can look better than the labour market feels.
• “A survey figure is exact.” Fix It is an estimate from a sample, so it carries sampling error. A change of a tenth of a percentage point between quarters may not be a real change at all. The informal economy is also missed: someone working for cash and claiming to be unemployed is counted as unemployed.

• All candidates take both papers. There is no tiering in this syllabus and no choice of route: every candidate answers the same Paper 1 and the same Paper 2, sits the whole of the subject content, and is eligible for grades A* to G. Examinations are available in the June and November series, and in the March series in India.
• Across the qualification the weights are AO1 43% knowledge and understanding, AO2 47% analysis and AO3 10% evaluation. Analysis is the largest single component, which is why every explanation in this chapter is written as a chain rather than as a list. Note that Paper 1 carries no AO3 at all: evaluation is assessed only on Paper 2, where it is worth 15% of the paper.
• Three item types recur: classify (is this fiscal, monetary or supply-side? progressive or regressive? cyclical or structural?), calculate (a budget balance, a growth rate, an unemployment rate, an inflation rate from index numbers) and diagnose (which policy fits this cause?). Each is answered by a definition you either hold precisely or do not.
• Two- to four-mark parts using define, identify, state, give or calculate. “Define fiscal policy” is answerable in one sentence, provided that sentence names both instruments and the target. Calculations need the working and the unit.
• Analysis parts, usually worth about six marks, such as “analyse how a rise in the interest rate could reduce inflation”. What is wanted is a developed chain rather than a list of separate points: three links and a consequence for the aim is a complete answer.
• The levels-marked discussion, usually worth about eight marks: whether a government should raise the interest rate, whether growth always benefits an economy, whether supply-side policy is the best cure for unemployment. Use DEAL: define, explain one side, argue the other, land a judgement naming the condition that decides it.
