The NHS at Breaking Point

Model Answer A merit good is a good or service where the social benefits exceed the private benefits perceived by the individual consumer, leading to under-consumption in a free market. Healthcare is a merit good because individuals often undervalue its long-run benefits — for example, preventive care reduces future disease burden not just for the patient but for the wider community, generating positive externalities that the market price does not capture.

Model Answer The diagram shows the healthcare market with quantity on the x-axis and price on the y-axis. The supply curve (S = MPC = MSC) is upward-sloping. There are two demand curves: the private marginal benefit (PMB) curve, which reflects only the individual's perceived benefit; and the social marginal benefit (SMB) curve, which lies to the right of PMB because healthcare generates positive externalities — a healthier population raises productivity, reduces the spread of infectious disease, and lowers long-run social costs.

In a free market, equilibrium is where PMB = S, at output Q_m. However, the socially optimal output is where SMB = S, at Q_opt, which is greater than Q_m. The free market therefore under-provides healthcare by the gap between Q_m and Q_opt. A deadweight welfare loss triangle exists to the right of Q_m, representing the net welfare gain forgone by under-provision.

Model Answer With 7.6 million on NHS waiting lists and an average wait of 14.5 weeks (Source A), a significant share of the UK workforce is experiencing untreated health conditions. The first economic effect is on labour productivity: workers in pain or suffering from untreated conditions are less able to perform at full capacity — presenteeism (being at work but underperforming) reduces output per worker. Employers face higher absenteeism and recruitment costs as illness forces temporary exits from the labour market, reducing the effective labour supply and worsening the UK's already weak productivity performance.

Second, there is a fiscal effect. Prolonged waiting times increase the likelihood that conditions deteriorate, requiring more expensive treatments when patients eventually receive care. This raises the long-run cost of healthcare provision relative to early intervention — a form of dynamic inefficiency where the short-run saving of deferred treatment generates higher long-run costs, putting additional pressure on public finances.

Third, the growth in private healthcare spending represents an increasing burden on household incomes. Source A shows 1 in 8 adults now uses private healthcare. For those who can afford it, this represents a welfare-improving choice; for those who cannot, the inability to bypass waiting lists perpetuates health inequality and further reduces labour market participation among lower-income workers.

Model Answer The growth of private healthcare can be interpreted as a market success in limited respects: consumers are exercising revealed preference — voluntarily paying premium prices for faster access, demonstrating that this meets a genuine need. The private sector arguably improves allocative efficiency for those who use it, directing resources toward those willing and able to pay. Competition from private providers may also create pressure on NHS efficiency.

However, a stronger case exists that this growth reflects market failure. The key issue is equity: those unable to afford private care face unequal access to treatment. Source A shows patient-reported unmet medical need in England at 12.4% — more than double France's 4.8% — suggesting widespread welfare loss for lower-income groups who cannot opt out of the NHS backlog. This violates the principle that healthcare, as a merit good, should be distributed according to need rather than ability to pay.

Furthermore, the growth in private use exacerbates NHS capacity pressures only partially — many private patients have already contributed through National Insurance, yet receive no NHS benefit commensurate with their contribution. The resulting two-tier system is not an equilibrium: it concentrates the most complex, expensive cases in the NHS (private providers cherry-pick routine and profitable procedures) while leaving the public system with increasing cost pressures and declining relative funding per case.

On balance, the rapid growth in private healthcare is better characterised as a symptom of market and government failure — specifically, the failure of the publicly funded system to deliver timely access — rather than an independently generated market success.

Model Answer — Level 4 Structure The case for the NHS rests on three interrelated market failures in healthcare. First, healthcare exhibits strong merit good characteristics: left to the market, under-consumption of preventive care, vaccinations and mental health services generates negative externalities — an unhealthier population imposes costs on employers, the welfare system, and other health users. The NHS, by providing free-at-the-point-of-use care, corrects this under-consumption and internalises the positive externalities.

Second, information failure is endemic in healthcare: patients cannot assess medical need with the competence of professionals, and a market system creates incentives for providers to induce demand (the "supplier-induced demand" problem). A state-funded system with salaried professionals is better placed to align provider incentives with patient need. Third, equity: a market allocates healthcare by willingness to pay — the poor receive less even if their medical need is greater. Source A confirms this problem exists even with the NHS: 12.4% unmet need in England versus 4.8% in France, suggesting the NHS is not fully delivering on its equitable access objective, but a pure market would worsen this substantially.

However, the evidence from Source A also highlights significant weaknesses of the NHS model. England has 2.4 hospital beds per 1,000 population, compared to 5.7 in France and 7.9 in Germany — despite spending 10.2% of GDP on health. The absence of price signals creates no mechanism for NHS supply to self-adjust to demand: 95% bed occupancy and 7.6 million waiting list patients indicate a chronic capacity failure that central planning has not resolved. France and Germany achieve superior outcomes through mixed public-private models that retain universal access principles while using price signals and competition to allocate resources more efficiently within the healthcare sector.

The evaluation depends on defining "preferable" precisely. For equity and market failure correction, the NHS model is superior to a pure market. However, Source A's comparative data suggests the NHS model as currently implemented is not the most efficient delivery mechanism for universal healthcare — mixed systems appear to achieve shorter waits, more capacity, and similar equity metrics at modestly higher cost. The case for the NHS is strongest as a principle of universal provision, not necessarily as a model of central delivery.
