[AO1 Knowledge & understanding] In a market system, resources are allocated by the price mechanism: the interaction of the demand of consumers and the supply of producers determines prices, and prices decide what is produced, how it is produced and for whom. Resources are mainly privately owned and producers aim to make a profit.

[AO2 Analysis] Prices perform three functions. The signalling function: when consumers want more of a good, for example electric scooters, demand rises and the price rises, which signals to firms that consumers value the good more highly. The incentive function: the higher price raises potential profit, giving firms such as Ola Electric and Ather an incentive to expand output and attracting new firms into the market. Resources (labour, capital, land) move from less profitable uses into producing electric scooters, while resources leave markets where demand and prices are falling, such as some petrol-vehicle components. The rationing function: when a good is scarce, the higher price reduces the quantity demanded, so the limited supply goes to the consumers most willing and able to pay. In this way the market answers what to produce (goods with the highest profitability reflect consumer demand), how to produce (firms choose the lowest-cost method to maximise profit) and for whom (goods go to those with the income to pay).

[AO3 Evaluation] The market system can allocate resources efficiently without central planning, but it does not always do so fairly or efficiently. Goods are allocated according to ability to pay, not need; public goods are not provided at all; merit goods are under-provided; and monopolies can restrict output. This is why most economies, including India, are mixed economies in which government also allocates some resources.

[AO1 Knowledge & understanding] A mixed economy allocates resources partly through the price mechanism and partly through the government. Planning means the government, rather than market forces, decides how some resources are used: through direct provision, state ownership, regulation, taxation and subsidies, or long-term development plans. India is a mixed economy that moved from extensive planning (five-year plans and the Planning Commission) towards a more market-based economy after 1991, and replaced the Planning Commission with NITI Aayog in 2015.

[AO2 Analysis] Planning has an important role where markets fail. Public goods such as defence, street lighting and flood defences are not provided by the market because of the free-rider problem, so the government must plan and finance them through taxation. Merit goods such as education and healthcare are under-consumed, so the government plans their provision, for example through government schools and the Ayushman Bharat health scheme. Demerit goods are over-consumed, so the government plans taxes and regulations to reduce consumption. Large infrastructure projects, such as national highways, dedicated freight corridors and the electricity grid, require long-term coordination and huge investment that private firms may not undertake alone. Planning can also be used to redistribute income through progressive taxes and transfer payments, and to achieve macroeconomic objectives such as stable prices and growth.

[AO3 Evaluation] However, planning also has limitations. Governments may lack the information to plan efficiently and can misallocate resources (government failure): India's experience before 1991, with industrial licensing and state control, led to slow growth, shortages and inefficient state-owned enterprises. Planned provision lacks the profit incentive, so it may be less efficient and less responsive to consumers than the market. Planning decisions may be influenced by political considerations rather than economic need. On the other hand, the market alone produces inequality and fails to provide public goods, so some planning is unavoidable. The important question is therefore not whether planning has a role but how much and what type: modern mixed economies tend to use "indicative" planning and regulation to guide markets, rather than replacing them.

[Conclusion (AO3 judgement)] Planning does have a role in a modern mixed economy, especially for public goods, merit goods, infrastructure and redistribution. Its role should be limited to areas where markets clearly fail, because extensive planning, as India found before 1991, can lead to serious inefficiency.

[AO1 + AO2 Knowledge & analysis] In a market economy, scarce resources are allocated through the price mechanism, which performs three linked functions: it signals relative scarcity and consumer preferences through changes in price, it incentivises producers to respond to those signals by reallocating resources towards more profitable uses, and it rations a limited supply of a good to those consumers most willing and able to pay for it. Because these adjustments happen continuously and automatically as conditions change, a market economy can allocate resources efficiently in response to shifting consumer demand without the need for a central planning authority to decide what, how and for whom to produce. The profit motive also encourages firms to innovate and cut costs, and prices adjust quickly to changes in demand and supply, avoiding the persistent shortages, surpluses and administrative burden often associated with centrally planned allocation.

[AO2 Analysis] However, the market mechanism allocates resources efficiently only where certain conditions hold, and these frequently break down. Pure public goods, such as national defence or street lighting, are non-excludable and non-rival, so private firms cannot profitably provide them the free-rider problem means they would be under-provided, or not provided at all, if left purely to the market. Where a good generates externalities, the price paid in the market reflects only the private cost or benefit, not the wider social cost or benefit, so goods with negative externalities (such as pollution-generating production) are over-produced, while goods with positive externalities (such as education or healthcare) are under-produced relative to the socially optimal quantity. Merit goods tend to be under-consumed because individuals do not fully value their long-run benefits at the time of the purchasing decision, and market power allows monopolies to restrict output and charge prices above the competitive level, misallocating resources away from what consumers would otherwise choose.

[AO3 Evaluation] A further limitation is that a market economy allocates resources according to purchasing power rather than need: households with low incomes may be unable to afford goods and services that are essential to their wellbeing, so purely market-based allocation can leave basic needs unmet even while resources are being allocated 'efficiently' in a narrow economic sense. This is one reason why almost no real-world economy operates as a pure market economy nearly all are mixed economies, in which the government intervenes through taxation, subsidies, regulation, and direct provision of public and merit goods specifically to correct these areas of market failure.

[Conclusion (AO3 judgement)] On balance, a market economy is generally an effective way of allocating resources for the majority of private goods, where competition and responsive prices deliver efficiency without the information and incentive problems that undermine central planning. However, its claim to be the 'best' system overall needs significant qualification: for public goods, goods with substantial externalities, merit goods, and in the presence of significant inequality, an unregulated market allocates resources poorly. The most defensible conclusion is that a mixed economy a market system with targeted government intervention aimed specifically at these sources of market failure is likely to allocate scarce resources better than either a pure market economy or a fully planned economy.
