Developed by Nobel economist James Heckman, the Heckman Curve shows that the highest rate of economic returns comes from the earliest investments in children.

Instead of waiting until secondary school or adult life to address structural inequalities, the model proves that early intervention is the most economically efficient approach. It shows the economic benefits of investing early and building skill upon skill to provide greater success to more children and greater productivity and reduce social spending for society.

From an A-level perspective, early years education perfectly illustrates the concept of a merit good generating positive externalities.

Left entirely to the free market, there would be under-provision of early childhood development. This happens because parents make investment decisions without internalizing wider societal benefits, and this underinvestment due to market failures is inefficient.

The free market ignores the fact that a more skilled population also benefits society by being more productive and innovative, helping to drive economic growth.

Furthermore, the long-term fiscal benefits are undeniable: higher earners pay more tax which funds public services, and because they are less likely to commit crime and tend to be healthier so society pays less money for the NHS, police, prisons.

In macroeconomic terms, effective early years intervention is a foundational supply-side policy. By improving the quality of the future labour force, it shifts the Long-Run Aggregate Supply (LRAS) curve to the right, expanding the productive potential of the economy far more effectively than late-stage adult job-retraining programmes.

We can see the practical magic of the Heckman Curve by examining the legacy of the UK's Sure Start programme. When evaluating government policies, economists look for empirical evidence, and the data on Sure Start is strong.

The Health Impacts of Sure Start, IFS 2021 shows that the most disadvantaged children made the greatest gains in health and resilience right into their adolescence. By creating a localised, community-based support network for parents, Sure Start children's centres prevented 13 000 hospital admissions a year. This acts as a real-world example of how targeted government spending can correct market failure. It directly reduces the future financial burden on state healthcare systems while simultaneously building the cognitive and emotional capital required for lifelong productivity.

Recognising these economic and social returns, the current UK government has placed early years intervention at the heart of its long-term economic strategy. The government is focused on breaking down barriers to opportunity, giving every child the best start in life, and breaking the unfair link between family background and future success.

In a major policy update in September 2026, Health Secretary Yvette Cooper announced a revival of the New Labour-era Sure Start scheme, with new parents getting support with their babies at more than 1,000 centres across England by 2028. By committing to bring back Sure Start health services into every family centre, she enthusiastically described the initiative as "One of the Labour Party's greatest achievements restored to families". Reaching up to 1,000 hubs over the next two years, this policy rollout directly targets the mental health, feeding, and bonding support necessary to give children a solid developmental foundation.
