Methodology and key assumptions

Total public spending projections

Focus on health spending

Summary and conclusions

Page 3: Long term public spending trends*

PricewaterhouseCoopers LLP6 March 2006

How do you project long-term public spending as % of GDP?

Start with GAD population projections in five year age bands

Assume trend labour productivity growth = 2% per annum

Assume plausible path for employment rates by age band/gender

Derive implied trend GDP growth profile (c.2.25% pa to 2014/15; then c.2% per annum on average over next 40 years)

Input estimates of spending as % of GDP per capita in base year for health, long-term care and education by age band

Make plausible assumptions on trend real growth in unit costs for each of these three spending categories (c.2.5%/2%/2%)

Use separate model to project state pension costs

What drives NHS spending in long run?

Any additional ‘catch-up’ over next 5 years (Wanless: 4.4-5.6% real growth; we assume bottom end of this range)

Pure age effects - more older people -> higher costs (survivors)

Number of deaths -> change in death-related costs

Offset from healthy ageing -> perhaps c.50% of pure age costs

Non-demographic factors:

- Income elasticity of demand > 1 (superior good)

- Technological advances and relative price effects

Summary and key issues

PwC and Treasury projections similar apart from NHS spending

- explained by our inclusion of non-demographic cost pressures

But: both sets of projections see rise in total public spending to around 45-47% of GDP by 2054/55 (c.42% at present)

Higher longevity might increase this; higher employment rates or healthier lifestyles might reduce the pressure on future taxpayers

Raises issues as to:

- Potential pressure on NHS model if unit costs rise in line with historic trends: how can these cost pressures be mitigated?

- Are there other major areas of public spending that can be reduced as a share of GDP?

- Balance between private and public spending?
