5.1.1 Objectives of Government Budget
The government budget is not merely a statement of expected receipts and expenditure. It is the government’s primary tool for influencing the economy and improving the welfare of its citizens. The textbook identifies three core functions that the budget performs: the allocation function, the redistribution function, and the stabilisation function. Each addresses a different limitation of the market economy.
Allocation Function
Markets are remarkably efficient at producing and distributing most goods — clothes, cars, food items — through the price mechanism. But there is a class of goods that markets systematically fail to provide in adequate quantities. These are public goods. Examples include national defence, roads, government administration, and public parks.
To see why the government must step in, we need to contrast public goods with private goods. Two features set them apart.
1. Rivalry in consumption.
A private good is rivalrous: if one person eats a chocolate or wears a shirt, that same chocolate or shirt cannot be consumed by someone else. One person’s consumption directly reduces the amount available for others. Public goods are non-rivalrous. If you enjoy a public park or benefit from cleaner air, your enjoyment does not diminish the amount of park or clean air available for anyone else. Many people can consume the same unit simultaneously.
2. Excludability.
A private good is excludable: if you do not pay for a movie ticket, you can be physically prevented from watching the film. The seller can enforce payment. Public goods are non-excludable: once a public good is provided, there is no feasible way to prevent anyone from enjoying its benefits, even if they have not paid. You cannot stop a person from breathing cleaner air or from walking on a public road.
A common mistake is to think that “public good” means “provided by the government.” That is not the definition. A good is a public good because of its technical characteristics — non-rivalry and non-excludability — not because of who produces it. The government provides it because the market fails to do so.
The combination of non-rivalry and non-excludability creates a problem: free-riders. Since no one can be excluded from the benefit, consumers have no incentive to pay voluntarily for what they can get for free. The normal link between producer and consumer — payment in exchange for the good — is broken. The market cannot solve this on its own, so the government must step in to provide such goods.
The textbook makes an important distinction between public provision and public production.
- Public provision means the good is financed through the budget and made available to users without any direct payment (e.g., a toll-free road).
- Public production means the good is actually produced by the government itself (e.g., a government-owned defence factory).
A publicly provided good may be produced by the private sector (the government contracts a private firm to build a road) or by the government directly. The key is that the budget pays for it.
Redistribution Function
In Chapter 2 of the textbook, you learned how national income is divided. The total national income of a country flows to two broad sectors: the private sector (firms and households) — called private income — and the government — called public income. Out of private income, what finally reaches households is personal income, and after paying direct taxes, what households can actually spend is personal disposable income.
The government can alter the distribution of income through two instruments in the budget:
- Taxes — it collects taxes from those with higher incomes.
- Transfers — it makes payments (subsidies, pensions, welfare benefits) to those with lower incomes.
By taxing the rich and transferring to the poor, the government changes the pattern of personal disposable income across households. This is the redistribution function. The goal is to bring about a distribution of income that society considers “fair” — a normative judgement that the market outcome alone may not satisfy.
Redistribution does not mean the government takes all income and reallocates it. It means the budget modifies the market-determined distribution through taxes and transfers. The net effect is that the post-budget distribution is more equal than the pre-budget distribution.
Stabilisation Function
The third objective addresses the problem of economic fluctuations — booms and recessions. The overall level of employment and prices in an economy depends on aggregate demand, which in turn depends on the spending decisions of millions of private agents (households and firms) plus the government. These private decisions are influenced by many factors — income, credit availability, expectations, and so on.
The problem is that aggregate demand does not always settle at the level needed for full employment of labour and other resources. Two situations can arise.
1. Deficient demand (recession).
There may be periods when aggregate demand is too low to fully utilise the economy’s labour and capital. Because wages and prices are sticky downward (they do not fall easily), the economy cannot automatically return to full employment. The government must intervene to raise aggregate demand — typically by increasing its own spending or cutting taxes.
2. Excess demand (inflation). …
