How to use these macroeconomics practice questions
These questions cover the core relationships usually tested in introductory and intermediate macroeconomics: national income, inflation, unemployment, aggregate demand and supply, fiscal policy, monetary policy, exchange rates and economic growth.
Answer each question on the page before reading the explanation beneath it. The purpose is not only to select the right option. It is to identify the economic mechanism that makes one option correct and the others unsuitable.
For calculation questions, show the relationship in your head or on paper before choosing. For policy questions, separate the immediate effect from the longer-term effect. That distinction is often where otherwise plausible answers fail.
Question 1 — Real and nominal GDP
This tests whether you can distinguish a change in prices from a change in the quantity of final goods and services produced.
MySummaries turns the first question into a marked item like this:
An economy produces 100 units in Year 1 at $10 each and 100 units in Year 2 at $12 each. Which statement is correct?
Nominal GDP uses each year's current prices: it rises from $1,000 to $1,200, or 20%. Real GDP uses a constant price, so output remains 100 units and real GDP is unchanged. The strongest distractor is both nominal and real GDP rising by 20%; that would incorrectly treat a price increase as an increase in physical output.
The key is the price base. Nominal GDP changes when prices or quantities change; real GDP is intended to isolate the quantity change. A rising nominal value does not by itself prove that the economy produced more.
Question 2 — The consumer price index
This tests the calculation and interpretation of an inflation rate based on a price index.
The consumer price index rises from 125 to 130 over one year. What is the approximate inflation rate?
Inflation is the percentage change in the index: (130 − 125) ÷ 125 × 100 = 4%. The strongest distractor is 5%, which uses the absolute five-point increase as if it were a percentage of 100 rather than of the original index value, 125.
Use the starting index as the denominator. A five-point increase has a different percentage meaning when the index starts at 100, 125 or 250.
Question 3 — The output gap
This tests the difference between actual output and an economy's estimated potential output.
An economy's potential output is $2,000 billion and its actual output is $1,900 billion. What is the output gap as a percentage of potential output?
The output gap is (actual output − potential output) ÷ potential output × 100: (1,900 − 2,000) ÷ 2,000 × 100 = −5%. The negative sign indicates output is below estimated potential. The strongest distractor is 5%, which gives the size but loses the economically important direction.
A negative output gap is commonly associated with spare capacity, although the precise relationship with inflation depends on expectations, supply conditions and other features of the economy. Do not describe the gap as a measured unemployment rate: they are different indicators.
Question 4 — The spending multiplier
This tests how an initial change in autonomous spending can affect equilibrium income when the marginal propensity to consume is known.
In a simple closed economy, the marginal propensity to consume is 0.75. If autonomous investment rises by $20 million, by how much does equilibrium income initially rise according to the simple spending multiplier?
The multiplier is 1 ÷ (1 − MPC) = 1 ÷ 0.25 = 4. The total change in income is therefore 4 × $20 million = $80 million. The strongest distractor is $60 million, which multiplies the investment change by the MPC but omits the repeated rounds of induced consumption.
The simple result assumes no taxes, imports or other leakages. In a more realistic model, these leakages reduce the multiplier, so do not transfer the closed-economy result without checking the assumptions.
Question 5 — Expansionary fiscal policy
This tests the direction of the short-run effects of government spending and taxation decisions.
An economy is operating below potential output with weak private demand. Which policy is most directly expansionary in the short run?
Higher government purchases enter aggregate demand directly, while lower income taxes can raise disposable income and consumption. The strongest distractor is increasing taxes with unchanged government purchases: it generally reduces disposable income and aggregate demand, making it contractionary rather than expansionary.
The size of the eventual effect depends on the multiplier, spare capacity, financing, confidence and the response of monetary policy. The direction is more reliable than a precise numerical forecast.
Question 6 — Monetary policy and interest rates
This tests the transmission from a central bank's policy decision to borrowing, spending and aggregate demand.
A central bank lowers its policy interest rate during a period of weak demand. Which chain is most consistent with the usual short-run transmission mechanism?
A lower policy rate can reduce market borrowing costs, encouraging interest-sensitive consumption and investment and therefore increasing aggregate demand. The strongest distractor reverses the borrowing-cost relationship. Actual transmission can be weaker when banks restrict lending or households and firms are unwilling to borrow.
Do not present this as a guaranteed one-step result. Exchange rates, asset prices, expectations, bank lending and the policy response all affect the eventual outcome.
Question 7 — Cost-push inflation
This tests whether you can distinguish a negative supply shock from excess demand.
A sharp rise in imported energy prices raises firms' costs across the economy. In the short run, what combination is most likely?
Higher energy costs shift short-run aggregate supply left. With aggregate demand unchanged, the price level rises while real output falls: a combination often called stagflation. The strongest distractor is higher prices and higher output, which is more consistent with a rightward demand shift, not a negative supply shock.
A supply shock creates a policy trade-off. Measures that reduce inflationary pressure may further weaken output, while measures that support demand may prolong price pressure.
Question 8 — Unemployment measurement
This tests the distinction between the unemployment rate and the labour-force participation rate.
A worker stops looking for a job because they believe no suitable jobs are available. What is the most direct statistical effect, assuming nothing else changes?
A person who is neither employed nor actively seeking work is generally classified outside the labour force in standard labour statistics. The number of unemployed can fall and the labour force can shrink, so the unemployment rate may fall even though the person's employment situation has not improved. The strongest distractor is that unemployment must rise; it confuses being without a job with being counted as unemployed.
Always check the statistical definition used by the data provider. International comparisons can be affected by survey methods and definitions of active job search.
Question 9 — Exchange-rate appreciation
This tests the likely effect of a currency appreciation on trade flows, holding other conditions constant.
Holding other factors constant, a country's currency appreciates. What is the most likely short-run effect on its net exports?
An appreciation raises the foreign-currency price of the country's exports and lowers the domestic-currency price of imports. This tends to reduce net exports, although the size and timing depend on demand elasticities and existing contracts. The strongest distractor reverses the price effects of appreciation.
Separate the exchange-rate movement from its cause. A higher currency value may result from tighter monetary policy, stronger capital inflows or improved confidence, and those causes can affect demand in other ways.
Question 10 — Long-run economic growth
This tests the role of productivity rather than merely identifying a larger quantity of inputs.
Which change is most directly associated with higher long-run potential output per worker?
Better technology and skills can allow each worker to produce more, raising labour productivity and potential output over time. The strongest distractor is a temporary increase in borrowing: it may raise demand, but it does not necessarily increase the economy's productive capacity per worker.
A strong growth answer distinguishes demand-led increases in actual output from supply-side increases in potential output. Investment in physical capital, human capital, research and development, and institutions can contribute, but the effect depends on how effectively resources are used.
Review the pattern, not just the score
After completing the set, classify each error:
- Definition error: you confused a term such as nominal GDP, real GDP or the labour force.
- Direction error: you knew the policy but reversed its effect on demand, prices or output.
- Calculation error: you used the wrong base, sign or multiplier.
- Assumption error: you applied a simple model without checking its conditions.
A useful review record should show both the topic and the reason for the lost mark. For example, “multiplier — used MPC rather than 1 ÷ (1 − MPC)” is more useful than “multiplier — wrong”.
Reattempt the weakest section with a fresh question. Do not simply reread the explanation: state the relationship aloud, calculate it again, or draw the relevant shift in a small aggregate-demand-and-supply diagram.
You lost this mark twice: with MPC = 0.8, what is the simple spending multiplier, and what assumption makes the result unrealistic?
A compact marking method
For future macroeconomics practice questions, give yourself one mark only when you can do all three things:
- Select the correct answer.
- State the mechanism in one sentence.
- Reject the strongest distractor by identifying its incorrect assumption or reversed relationship.
That method prevents recognition from being mistaken for understanding. It also gives you a precise revision task: definitions, diagrams, calculations, policy transmission or model assumptions.
