Economic planning: meaning, objectives and principles

1Case: 250,000 jobs a year

Rwanda's Second National Strategy for Transformation (NST2) sets a target of 1.25 million "productive and decent" jobs between 2024 and 2029, which is 250,000 a year (MINECOFIN, NST2 2024–2029, p. 23). In 2025 about 4.8 million people were employed and about 676,000 were unemployed (NISR, Labour Force Survey Annual Report 2025, p. 8).

The government itself will employ only a small part of those workers. Most of the new jobs must come from farms, firms, cooperatives and the self-employed, and each of them makes its own decisions. Think: if the state does not do most of the hiring, why write the target down at all? What would a plan have to contain to be more than a wish?

2What a plan is made of

1. Objectives: the broad aims, such as "more productive jobs".
2. Targets: objectives turned into numbers with a date, such as "1.25 million jobs by 2029".
3. Instruments: the tools the state controls, such as public investment, taxes and subsidies, credit and interest rates, regulation and public enterprises.
4. Institutions: a planning authority, and a named body responsible for each part.
5. Monitoring and evaluation: indicators, baselines and regular reports that show whether the plan is working.

Planning is a matter of degree. In a free-market economy, prices coordinate millions of separate decisions; in a command economy, a central planning office decides what is produced and at what price. No real economy sits at either extreme: even the most market-based governments plan their roads, schools and budgets. The real questions are how much the state decides itself, and how it persuades everyone else to act.

3Objectives of economic planning

Plans usually add further aims: a fairer distribution of income between people and regions, stable prices, and protection of the environment, so that growth does not use up the land, water and forests that later generations need.

4Principles of planning

Whatever its type, a plan should follow these principles.

• Consistency. Make sure the targets do not contradict each other and add up to no more than the resources available.
• Priority. Rank the uses of scarce capital, foreign exchange and skills, putting first the projects with the highest returns or strongest linkages.
• Realism. Set targets that the country's finance, skills, institutions and data can actually support.
• Flexibility. Allow revision when a drought, a pandemic or a price shock changes the situation.
• Coordination. Keep national, sector and district plans and the annual budget pointing the same way.
• Participation. Involve the people affected, which improves both the information and their commitment.
• Continuity. Build each plan on the last one, inside a longer vision.
• Accountability. Name who reports on each target, and how often.

5Consistency made precise: Tinbergen's rule

The Dutch economist Jan Tinbergen, in On the Theory of Economic Policy (1952), showed that a planner who wants to reach several independent targets at the same time needs at least as many independent instruments as targets. With fewer instruments than targets, the planner must accept a trade-off or find a new instrument. The diagram shows the simplest case.

6Why do developing countries plan?

• Market failure. Markets under-supply public goods such as feeder roads, research and statistics, because non-payers cannot be excluded. Prices also ignore externalities: a farmer who terraces a hillside protects the farms below, but is not paid for it.
• Coordination failure. Many investments pay only if others are made at the same time: a factory needs power, roads and suppliers. This is the "big push" problem of Unit 8.
• Scarce resources need priorities. Capital, foreign exchange and skilled people are short, so they must be rationed to the uses that matter most.
• Long-term projects. Power stations, railways and universities take decades to pay back; private investors with short horizons avoid them.
• Structural change. Left alone, labour may stay for a long time in low-productivity farming.
• Equity. Markets reward those who already own land, capital and skills, so gaps between people and between regions can widen.
• Mobilising finance. A plan frames the budget, the tax effort and borrowing, and lets development partners align their aid behind national priorities instead of their own.
• Population growth. Schools, clinics and jobs for today's children must be planned years in advance.

7The case against central planning

• The knowledge problem. Friedrich Hayek ("The Use of Knowledge in Society", American Economic Review, 1945) argued that knowledge of local conditions, costs and wants is scattered among millions of people. No planning office can collect it, whereas prices sum it up automatically.
• The calculation problem. Ludwig von Mises (1920) argued that without market prices for capital goods, planners cannot compare the costs of different methods rationally.
• Incentives. Managers who are judged on meeting a quota may produce the wrong goods, or poor ones.
• Government failure. Plans can suffer from slow bureaucracy, rent-seeking and corruption, and projects chosen for political rather than economic reasons.
• Rigidity. A target fixed for five years may be wrong by year two.

Weighing it up. The 20th-century record shows the costs of trying to plan everything centrally, but also that markets alone did not build the infrastructure, skills and institutions that late developers needed. Most developing countries today therefore use planning to guide a market economy rather than replace it. Lesson 2 shows how.
