Difficulty: Introductory. Assumes you have read the microeconomics fundamentals notes (or are comfortable with scarcity, trade-offs, and basic market concepts). No maths beyond arithmetic.
Macroeconomics steps back from individual consumers and firms to look at the economy as a whole. It asks: how do we measure the total output of a country? Why do prices rise over time? What tools does a government have when the economy slows down?
This set of topics also reaches into international trade (why countries trade and what happens when imports exceed exports) and the impact of technology on labour markets. These themes tie together because government policy, trade patterns, and technological change all shape the same macroeconomic outcomes: employment, output, and the distribution of income.
If you are behind on micro (individual decisions, opportunity cost, elasticity), review that first. Macro builds on top of it.
GDP measures a country's total output. Inflation is a sustained rise in the general price level. Governments use fiscal policy (spending and taxation) to stabilise the economy, while central banks like the Federal Reserve manage monetary policy. In international trade, comparative advantage explains why countries specialise, and trade deficits are more nuanced than they first appear.
Gross Domestic Product (GDP)
The total monetary value of all finished goods and services produced within a country's borders in a specific time period, usually one year or one quarter. Think of it as the economy's scorecard for how much stuff it produced.
Inflation
A sustained increase in the general price level of goods and services over time. In simple terms, the same basket of shopping costs more this year than it did last year. It is measured by indices such as the CPI (Consumer Price Index).
Deflation
The opposite of inflation: a sustained decrease in the general price level. Often a sign of economic trouble, as it can discourage spending (why buy today if prices will be lower tomorrow?).
Fiscal policy
The use of government spending and taxation to influence the economy. When the government increases spending or cuts taxes to boost demand during a downturn, that is expansionary fiscal policy.
Monetary policy
The actions of a central bank (such as the Federal Reserve) to manage the money supply and interest rates. Distinct from fiscal policy, which is controlled by the government's treasury or finance ministry.
Federal Reserve (the Fed)
The central banking system of the United States. It sets monetary policy, regulates banks, and acts as a lender of last resort. Think of it as the institution that controls the supply of money and the cost of borrowing in the US economy.
Trade deficit
A situation where a country's imports exceed its exports in value. In simple terms, the country is buying more from abroad than it is selling. This does not necessarily mean the country is "not producing enough," as it may reflect strong consumer demand or capital inflows.
Comparative advantage
The ability of a country (or individual) to produce a good at a lower opportunity cost than another. This is the principle behind why countries trade: each specialises in what it gives up least to produce, and both sides benefit.
Absolute advantage
The ability to produce a good using fewer resources than another producer. Often confused with comparative advantage, but they are different concepts. A country can have an absolute advantage in everything and still benefit from trade based on comparative advantage.
Automation
The use of technology to perform tasks previously done by human workers. In economics, the key question is how automation affects employment levels and the distribution of income across skill levels.
GDP stands for Gross Domestic Product.
"Gross" means total, before accounting for depreciation of capital.
"Domestic" means within the country's borders (regardless of the nationality of the producer).
"Product" means the value of finished goods and services.
GDP is the single most-used measure of an economy's size and health. When news reports say "the economy grew 2%," they mean real GDP increased by 2%.
GDP can be calculated three ways: the expenditure approach (add up all spending), the income approach (add up all income earned), and the production approach (add up the value added at each stage). All three should arrive at the same number.
Limitations: GDP does not capture unpaid work (household labour, volunteering), the underground economy, environmental degradation, or the distribution of income. A country with high GDP can still have deep inequality.
Inflation is a sustained increase in the general price level of goods and services.
It is not the same as one item becoming more expensive. Inflation refers to the overall price level across the economy.
Common causes:
Demand-pull inflation: too much money chasing too few goods. Aggregate demand outstrips supply.
Cost-push inflation: rising production costs (wages, raw materials, energy) push prices up from the supply side.
Moderate inflation (around 2% per year in most developed economies) is generally considered healthy. It encourages spending and investment rather than hoarding cash.
High or unpredictable inflation erodes purchasing power, makes planning difficult for businesses, and tends to hurt people on fixed incomes most.
Fiscal policy refers to government decisions about spending and taxation.
To combat a recession, the standard fiscal tool is expansionary policy:
Increasing government spending (building infrastructure, funding public services) injects money into the economy and creates jobs.
Cutting taxes leaves consumers and businesses with more disposable income to spend.
The exam specifically tests this: increasing government spending is a fiscal policy tool used to combat a recession.
Raising interest rates is monetary policy, not fiscal policy. This is a common trap.
Decreasing government spending and selling government bonds are contractionary measures, used to cool an overheating economy, not to fight a recession.
Fiscal policy is set by the legislature and executive branch (e.g. Congress and the President in the US), not by the central bank.
The Federal Reserve is the central banking system of the United States. This is a straightforward definitional point and it is true.
The Fed's main tools include:
Setting the federal funds rate (the interest rate at which banks lend to each other overnight), which influences borrowing costs across the economy.
Open market operations: buying or selling government bonds to increase or decrease the money supply.
Reserve requirements: setting the minimum amount of reserves banks must hold.
The Fed operates independently of the elected government, though its chair is appointed by the President. This independence is designed to keep monetary policy decisions insulated from short-term political pressure.
A trade deficit occurs when a country's imports exceed its exports.
A trade deficit does not mean a country is "not producing enough goods and services." This is a false and commonly tested statement.
A country can run a trade deficit because its consumers are wealthy and demand a wide variety of imported goods.
It can also reflect capital inflows: foreign investors sending money into the country to buy assets, which shows up as a trade deficit on the current account but a surplus on the capital account.
Whether a trade deficit is "good" or "bad" depends on context. Persistent deficits financed by debt may be concerning, but a deficit in itself is not evidence of economic weakness.
Comparative advantage is the idea that countries should produce what they can produce most efficiently, meaning at the lowest opportunity cost.
This is different from absolute advantage. A country might be better at producing everything, but it still benefits from specialising in the goods where its opportunity cost is lowest and trading for the rest.
David Ricardo's classic example: even if England is better than Portugal at producing both cloth and wine, if England's relative advantage is greater in cloth, England should specialise in cloth and import wine from Portugal. Both countries end up better off.
Comparative advantage is the theoretical foundation for free trade. It explains why countries trade even when one country could, in principle, produce everything more cheaply.
Technological advancement has led to increased automation in various industries.
Manufacturing, logistics, and increasingly service roles (data entry, customer service) are being automated.
The effect on employment is uneven:
Workers with specialised skills (engineering, software development, data analysis) tend to benefit: their productivity rises and their wages grow.
Low-skilled workers face displacement. Routine manual and cognitive tasks are most vulnerable to automation.
This pattern contributes to income inequality: the gap between high-skilled and low-skilled workers widens.
Potential solutions discussed in the literature:
Investing in education and retraining programmes so displaced workers can move into new roles.
Establishing universal basic income (UBI) to provide a floor of economic security.
Creating a supportive environment for entrepreneurship, so new businesses and job categories can emerge.
The essay version of this question expects you to discuss both the problem (displacement and inequality) and the solutions (policy responses), not just one side.
GDP growth figures drive everything from stock markets to election outcomes. When GDP contracts for two consecutive quarters, economists typically call it a recession, and that label triggers policy responses.
Fiscal policy was deployed at enormous scale during the 2008 financial crisis and the COVID-19 pandemic, when governments worldwide increased spending to prevent economic collapse. The US Federal Reserve simultaneously cut interest rates to near zero, illustrating how fiscal and monetary policy work in tandem.
Comparative advantage explains why your phone is assembled in one country from components made in a dozen others. Each supplier specialises where their opportunity cost is lowest.
Students often confuse fiscal policy with monetary policy. Fiscal = government spending and taxes (controlled by the legislature). Monetary = interest rates and money supply (controlled by the central bank). The exam tests this distinction directly.
A trade deficit is not inherently bad, and it does not mean a country "isn't producing enough." Many strong economies run persistent trade deficits.
GDP is not a measure of wellbeing. A country's GDP can grow while inequality deepens, environmental damage increases, and quality of life for many citizens declines.
Comparative advantage is not the same as absolute advantage. A country can be worse at producing everything and still have a comparative advantage in something, because comparative advantage is about relative opportunity cost.
⚠️ The GDP acronym question is free marks. Gross Domestic Product. Do not overthink it.
⚠️ Inflation is defined as an increase in the general price level, not a decrease (that is deflation) and not currency depreciation (a related but different concept).
⚠️ The fiscal policy question specifically asks what combats a recession. The answer is increasing government spending. Raising interest rates is monetary policy, and the other options are contractionary.
⚠️ "The Federal Reserve is the central banking system of the United States" is true. This is a definitional recall question.
⚠️ "A trade deficit means a country is not producing enough" is false. Be ready to explain why in one sentence.
⚠️ Comparative advantage means producing at the lowest opportunity cost, not producing the most efficiently in absolute terms. This distinction is the core of the concept.
⚠️ The essay question on technology and inequality expects both analysis (how automation causes displacement and inequality) and policy solutions (education, UBI, entrepreneurship support). Cover both to get full marks.

Q: What does GDP stand for?
A: Gross Domestic Product. It measures the total monetary value of all finished goods and services produced within a country's borders over a given time period.
Q: What is inflation?
A: An increase in the general price level of goods and services over time. It means the purchasing power of money is falling: the same amount of currency buys less than it did before.
Q: Which of the following is a fiscal policy tool used to combat a recession: raising interest rates, decreasing government spending, increasing government spending, or selling government bonds?
A: Increasing government spending. This is expansionary fiscal policy. Raising interest rates is monetary policy (and contractionary at that). Decreasing spending and selling bonds are contractionary measures.
Q: True or false: A trade deficit means that a country is not producing enough goods and services.
A: False. A trade deficit means imports exceed exports, but this can reflect strong consumer demand, capital inflows, or other factors. It is not evidence that the country is failing to produce enough.
Q: What is comparative advantage in international trade?
A: The principle that countries should specialise in producing goods where their opportunity cost is lowest, even if another country can produce those goods more cheaply in absolute terms. Both trading partners benefit from this specialisation.
Q: Discuss how technological advancement affects employment and income inequality.
A: Automation displaces workers in routine tasks (both manual and cognitive), disproportionately affecting low-skilled workers. Meanwhile, workers with specialised skills see rising productivity and wages. This widens income inequality. Policy responses include investment in education and retraining programmes, universal basic income, and support for entrepreneurship to create new job categories.
GDP connects to fiscal and monetary policy because those policies exist to influence GDP growth, employment, and price stability. When GDP falls, governments reach for fiscal stimulus; when it overheats, central banks tighten monetary policy.
Comparative advantage connects back to opportunity cost from the microeconomics notes: the entire logic of trade specialisation rests on comparing opportunity costs between producers.
The technology and inequality topic links to labour economics and public policy modules later in the course, where you study minimum wages, progressive taxation, and the economics of education in more depth.
