Resource Allocation
Definition
Price mechanism: the way changes in price signal what to produce, incentivise supply and ration scarce resources without central direction.
- The market economy and the planned economy sit at opposite ends of a spectrum.
- Each has clear advantages and clear disadvantages, so neither is wholly superior.
- The real debate is about the right balance of market and state in a mixed economy.
Key Idea
- Market economies tend to allocate resources efficiently and offer wide choice.
- Planned economies tend to allocate resources towards equity and stability.
How Allocation Happens
- In a market economy resources are allocated by the price mechanism through the signals that prices send.
- A rise in price signals higher demand and draws resources into that market, while a fall pushes them out.
- In a planned economy the state allocates resources directly by directing labour, capital and materials to chosen uses.
Note
- Prices carry information and incentives that central planners struggle to replicate.
- This is a key reason many planned economies have shifted towards markets.
Example
- Suppose a poor harvest sharply reduces the supply of wheat in a market economy.
- With less wheat available, its price rises, say from £200 to £300 a tonne.
- The higher price rations the scarce wheat to those most willing and able to pay.
- It also signals to farmers that wheat is now more profitable to grow.
- Farmers respond to this incentive by planting more wheat the next season, so signalling, incentive and rationing together pull resources back towards wheat with no central direction.
Advantages And Disadvantages
- Market: efficiency and choice
- Profit incentives push firms to cut costs and follow consumer demand, so resources flow to their most valued uses and choice is wide.
- Market: inequality and market failure
- Allocation by ability to pay can leave the poorest without essentials, and public goods and other market failures are under-provided.
- Planned: equity and stability
- State ownership can guarantee essentials for all and avoid the instability of unregulated markets.
- Planned: weak incentives and poor information
- Without prices or profit, planners lack the information and motivation to allocate well, so shortages and surpluses recur, as the long bread queues of the former Soviet Union showed.
Example
- Imagine both a market and a planned economy face rising demand for a popular good.
- In the market, the price rises and profit-seeking firms quickly expand supply to meet it.
- In the planned economy the fixed price cannot rise, so demand outstrips the planned quantity.
- Queues, waiting lists or rationing appear because there is no automatic incentive to produce more.
- The contrast shows the market's efficiency advantage and the planned system's tendency towards shortages.
Role Of The State
- The state provides public goods the market would under-supply, such as national defence.
- It corrects market failures through taxes, subsidies and regulation.
- It redistributes income to address inequality the market leaves behind.
How Much Intervention
- Too little intervention can leave market failures and inequality unaddressed.
- Too much can blunt incentives and create government failure of its own.
- The best balance therefore depends on a society's priorities between efficiency and equity, so it depends on the context.
Exam technique
- Weigh efficiency and choice against equity and stability rather than listing features.
- Bring in incentives and the differing objectives of consumers, firms and the state.
- Conclude on the appropriate balance rather than declaring one system best.
Common Mistake
- Do not argue that one system is simply superior, since each has strengths and weaknesses and the real question is the balance.
- Do not ignore government failure, since state intervention can also misallocate resources rather than only fixing problems.
Self review
- Give two advantages of the market economy.
- Give two advantages of the planned economy.
- What are the three functions of the price mechanism?
- State two roles of the government in a mixed economy.
- Why can too much state involvement be a problem?
