Three functions of the price mechanism
In a market economy the price mechanism works as a signalling device (rising prices signal where resources are most valued), an incentive device (profit encourages firms to move resources towards high-price goods), and a rationing device (higher prices reduce demand so scarce goods go to those willing and able to pay). Articulating all three with a chain of reasoning reaches higher levels on Analyse and Assess questions.
Four features of a market economy
A market economy has: (1) private ownership of the factors of production; (2) the profit motive driving producer decisions; (3) the price mechanism coordinating resource allocation without central direction; and (4) consumer sovereignty — consumer spending ultimately determines what is produced. These four features appear often in Define and Explain questions.
Market, planned and mixed economies
In a planned (command) economy the government owns most factors of production and directs allocation centrally. In a market economy decisions are decentralised to firms and households through price signals. Most real economies are mixed economies, in which both the private and public sectors play a role. Higher-mark Assess and Evaluate questions weigh the relative merits of these systems.

Define a market economy in two parts
A single-sentence definition such as "a market economy is where prices are set by supply and demand" collects only one mark. A two-mark "what is meant by" needs two distinct parts — for example private ownership AND the price mechanism allocating resources. Adding an example does not earn the second mark.
Paraphrased from the pattern observed across multiple sittings including June 2024 Paper 1R Q1(c) and November 2024 Paper 1, where examiners reiterated that "What is meant by" questions need two distinct parts and that examples are not credited.
No counter-argument in Analyse
On nine-mark Analyse questions the descriptor table has no AO4 (evaluation) marks — all nine reward AO1 knowledge, AO2 application and AO3 analysis. Presenting an opposing view earns nothing and reduces the time available to develop the actual chain of reasoning.
Paraphrased from November 2024 Paper 1 Q1(i) examiner report: "Do not present a counter argument in analyse questions as there are no marks for AO4. It will therefore leave less time to answer other questions."
Use extract data, do not copy it
On higher-mark Assess and Discuss questions, repeating figures from the source material earns no application marks. The data must be USED to develop or support a chain of reasoning — for example, citing a statistic to show why market forces failed in that context. Merely transcribing it does not score.
Paraphrased from June 2024 Paper 1R Q2(g): "Simply copying the extract will not lead to high marks. Instead, evidence needs to be used when answering the question." Also echoed in November 2024 Paper 1 summary advice.
Price mechanism vs profit motive
The price mechanism is the system through which prices allocate resources; the profit motive is one incentive that makes it work. They are related but not the same. Treating them as identical blurs the signalling, incentive and rationing functions in explain and analyse answers.
What consumer sovereignty means
Consumer sovereignty does not mean consumers get everything they want; it means producers ultimately respond to consumer spending patterns. Market failures such as information gaps can undermine it. Overstating it as "the consumer always wins" misses the point in an evaluation.
Planned economy vs intervention
A planned economy is not the same as a government intervening in a market economy. Even market economies tax, regulate and spend; the key question is who makes the PRIMARY resource-allocation decisions. Labelling any state action a "command economy" is wrong.
Structure a 12-mark Assess answer
A Level 3 Assess answer defines the concept briefly, develops one side using source evidence, develops a counter-argument also using evidence, then weighs both sides for a supported conclusion. Listing advantages and disadvantages without development caps at Level 2.
Explain the price mechanism as a chain
To explain how the price mechanism allocates resources, follow one chain: a rise in demand raises price (signal), higher profit draws in producers (incentive), resources shift in, and the higher price rations the good. One developed mechanism beats three undeveloped functions.
Match the answer to the command word
Define wants the meaning; Explain a chain; Analyse sustained one-sided chains with no evaluation; Assess and Evaluate both sides plus a judgement. Read the command word and its tariff first, then shape the answer to it — under-developing a high-tariff answer caps the band.
A market economy (also called a free-market or capitalist economy) is an economic system in which the key decisions about resource allocation — what to produce, how to produce it, and for whom — are made by private individuals and firms responding to price signals, rather than by a central authority.

| Private ownership | Factors of production (land, labour, capital, enterprise) are owned by private individuals and firms, not the state |
