1.2 - Resource allocation and incentives

Incentives and behaviour

An incentive changes the expected benefit or cost of an action and can therefore alter an agent's choice.

Financial incentives include prices, wages, profits, taxes, subsidies and fines. A higher wage raises the reward from supplying labour; a charge for parking raises the cost of driving into a city. Non-financial incentives include recognition, convenience, social approval and personal satisfaction. They can reinforce or conflict with financial rewards.

Follow the mechanism rather than assuming a reward guarantees a response. In an illustrative refill shop, a discount reduces the money cost of bringing a reusable container. Some households switch because the saving exceeds the inconvenience. Others cannot carry containers easily or do not know about the offer, so their behaviour changes little. The response depends on the size and visibility of the reward, feasible alternatives and the agent's objective.

Incentives can also produce unintended behaviour. Paying a call-centre employee for the number of completed calls may increase speed but reduce time spent solving difficult problems. If performance is measured imperfectly, the employee can rationally respond to the measured target rather than the organisation's wider objective. A reward may also reduce an activity's appeal when it displaces a sense of voluntary contribution. These possibilities require evidence; they do not mean all rewards fail.

To assess effectiveness, compare behaviour before and after while considering other changes, such as altered opening hours. Check the benefit against the cost of the scheme and distribution of the response. A discount used mainly by customers who already brought containers costs money while creating little additional reuse.

How economic systems allocate

Economic systems differ in who controls resources and how production and consumption decisions are coordinated.

In a market economy, private owners and consumers make decentralised decisions, coordinated mainly through prices. A higher relative price can signal stronger demand or greater scarcity. It offers producers an incentive to devote resources to that use and encourages buyers to economise. Purchasing power helps determine who receives goods. A market is therefore responsive to willingness and ability to pay, rather than simply to need.

In a planned economy, the state makes major allocation decisions, often owning productive resources and using output targets and administrative distribution. A plan can direct resources towards a collective priority such as basic housing. It requires information about resources, demand and technology and a means of motivating workers and managers to fulfil the intended purpose.

In a mixed economy, market decisions operate alongside government ownership, provision, regulation, taxation and transfers. Private supermarkets and publicly funded schools can coexist. Mixed is not a precise 50:50 division: the balance differs across sectors and countries, and public organisations may use prices while private firms are subject to rules.

The three questions are linked. A government providing healthcare decides the mix of services, the combination of staff and equipment and access criteria. A market firm chooses products expected to sell, methods that serve its objective and customers able to pay. Ownership alone does not tell you whether either method meets needs or uses resources efficiently.

Two meanings of efficiency

Efficiency concerns how well scarce resources are used, but two different questions must be kept separate.

Productive efficiency means producing a given output at the lowest possible cost, or obtaining the greatest feasible output from a given set of inputs. Avoidable waste or using an unnecessarily costly technique is productively inefficient. At the economy level, production is on its production possibility frontier rather than inside it; later lessons develop that model. In the firm's cost model, productive efficiency is associated with the lowest average cost, not simply any rise in profit.

Allocative efficiency means directing resources to the combination of goods and services that best satisfies society's wants. At the margin, the social benefit from the last unit should equal its social cost. If the benefit from another unit exceeds its opportunity cost, expanding that activity would improve allocation; if cost exceeds benefit, resources would be better used elsewhere. This marginal rule is developed further in the market-failure lessons.

Imagine an illustrative town can produce school meals using either a wasteful kitchen or an efficient kitchen. Switching to the efficient kitchen for the same number and quality of meals can improve productive efficiency. Producing the meals as cheaply as possible does not establish allocative efficiency: the town might still produce far more meals than pupils want while another valued service is underprovided. Equally, choosing the desired number of meals but wasting resources preparing them is not productively efficient.

Social benefit and cost require more than the seller's receipts and expenditure. Pollution affecting neighbours, for example, is not necessarily reflected in the firm's private calculation. Nor is willingness to pay a neutral measure of need when incomes differ. These are reasons to examine a market's allocation, rather than reasons to assume that government automatically selects a better one.

Comparing real allocations

A useful comparison explains how each system handles a particular allocation problem and what can prevent its intended gains.

Market prices can communicate dispersed information without a central authority knowing every preference. Prospective profit encourages experimentation and cost reduction; competition can make firms respond to consumers. However, market power can weaken that pressure, buyers may lack information and private decisions may overlook effects on third parties. Goods important to people with little income may attract fewer resources than luxuries for wealthy buyers.

Planning can coordinate large projects and make access less dependent on purchasing power. It can direct investment towards a long-term goal that private investors find difficult to finance. Yet planners may lack detailed local information, output targets may reward quantity instead of quality, and weak consequences for failure may reduce incentives to control costs. A shortage in one planned input can disrupt many dependent activities.

A mixed system can combine local choice with public provision or rules where market allocation is weak. But intervention itself uses resources and requires information. Poorly designed targets, administration costs or political priorities can reduce the expected gain. Combining systems does not remove the need to compare realistic alternatives.

Consider an illustrative rural bus route. A private operator may stop a route whose fares cannot cover costs, encouraging resources to move to more profitable uses. Residents without cars may then lose access to employment or healthcare, benefits not fully represented by fare revenue. Public support could preserve that access, but an empty bus with a costly timetable may waste funds. Comparing a targeted service, a different timetable and a subsidy requires evidence on use, cost and the benefits forgone elsewhere.

The judgement depends on the problem: market coordination is stronger when information and competition work well; public allocation is more convincing when an important benefit is missed and the intervention can deliver it at reasonable cost. Evaluate both the decision rule and the implementation. “Mixed is best” without a mechanism or relevant condition does not explain the allocation.

Quick recap

Incentives work by changing expected benefits and costs, subject to constraints and measurement. Economic systems coordinate allocation differently. Keep low-cost production separate from a socially desirable output mix, and compare actual mechanisms and realistic alternatives when judging an allocation.
