Factors to Consider in Intervening in the Pre-School Education Market

Answer

In deciding whether to intervene in the pre-school education market, the government should apply a decision-making framework: gather information on the market’s failure, weigh the benefits of intervention against its costs, and consider the constraints it faces and the unintended consequences that may follow. My thesis is that intervention is justified — the case for it rests on three sources of market failure — but the extent of intervention should be governed by a comparison of benefits against costs, conditioned by Singapore’s constraints and the risk of government failure.

Benefit 1 — correcting a positive consumption externality. Pre-school education confers benefits on third parties: a child who develops strong cognitive skills early is more likely to complete more schooling and join a more productive, innovative workforce, raising society’s output beyond the gains to the child’s own family. These marginal external benefits (MEB) drive a wedge between marginal private benefit and marginal social benefit, with $MSB = MPB + MEB$ ; assuming no production externality, $MSC = MPC$ .

Positive consumption externality in pre-school education: MSB lies above MPB by the MEB. The free market consumes at Qp where MPB = MPC; the social optimum is Qs where MSB = MSC. Under-consumption of Qp–Qs generates the deadweight welfare loss triangle ABC.

In self-interest, consumers consume at $Q_p$ where $MPB = MPC$ , below the social optimum $Q_s$ where $MSB = MSC$ ; the under-consumption of $Q_pQ_s$ units yields a deadweight loss ABC and allocative inefficiency. Intervention via a subsidy lowers MPC by the subsidy per unit, raising consumption to $Q_s$ and restoring allocative efficiency.

Evaluation. Because of imperfect information, the MEB is hard to measure accurately, so the “correct” subsidy that internalises the externality is difficult to set — over- or under-subsidising both impose welfare costs.

Benefit 2 — correcting imperfect information. Pre-school is also a merit good: parents tend to undervalue its private benefits, perceiving it as the acquisition of simple knowledge while underestimating its true developmental value. The perceived MPB lies below the actual MPB, so the market under-consumes relative to even the privately optimal level.

Imperfect information: parents act on MPB(perceived), consuming Qp′ where it meets MPC; the informed level is Qa where MPB(actual) = MPC. The information gap causes under-consumption of Qp′–Qa and welfare loss ABC, closed when an education campaign shifts demand from MPB(perceived) to MPB(actual).

Here the appropriate instrument is information provision — public-education campaigns on the true benefits of pre-school — which shifts demand from MPB(perceived) toward MPB(actual), eliminating the welfare loss.

Evaluation. Information correction alone may be insufficient: an informed lower-income parent who now wishes to enrol their child may still be unable to afford the fees — pointing to a complementary affordability instrument.

Benefit 3 — improving equity. Inequality in family resources produces achievement gaps that appear very early in a child’s life. Subsidising pre-school for lower-income families, as the preamble’s targeted assistance does, levels the playing field and widens equitable access to future tertiary and career opportunities. This is a normative goal — reducing inequity — distinct from the efficiency case.

Costs and constraints. Against the benefits, intervention has costs: the subsidy outlay and the construction cost of new pre-school centres, which carry an opportunity cost — the alternative public uses of those funds. Singapore also faces a binding land constraint: scarce land must be allocated among pre-school centres, eldercare, and commercial development, so expansion is not costless. Over-intervention risks government failure — mis-set subsidies, or provision crowding out efficient private providers.

Judgement. Intervention in the pre-school education market is justified, because the market fails on three distinct grounds — a positive consumption externality, imperfect information, and inequity — each of which leaves the free market under-providing relative to society’s interest. But the most important factor the government should weigh is the balance of benefits against costs: it should allocate resources to pre-school education up to the point where the marginal social benefit of doing so equals the marginal social cost, no further. The decision is also conditioned by priorities and constraints — chiefly land scarcity and competing public claims on the budget. Given the strong externality and equity case, and pre-school’s foundational role in long-run productivity and social mobility, the benefits to Singapore plausibly outweigh the costs, so substantial intervention — combining subsidy, targeted assistance and information provision — is warranted, calibrated to avoid government failure.
