“Beyond its intrinsic value, improved health contributes to social well-being through its impact on economic development, competitiveness and productivity. High-performing health systems contribute to economic development and health”
EU Health Strategy“Together for Health: A Strategic Approach for the EU 2008-
2013”
• Fundamental principles for EC action on health:
1) A strategy based on shared health values2) "Health is the greatest wealth“3) Health in all policies (HIAP)4) Strengthening the EU's voice in global health
“.....the time is ripe for ourmeasurement system to shift emphasis from measuring economic production tomeasuring people’s well-being.”

...but what is the evidence behind the Health is Wealth story?
• The economic consequences of health depend on:– What precisely we mean by economic consequences
/costs, and– How we measure them
• There is a strong economic case for investment in health but it is nuanced– The better we are able to understand and communicate
that nuance, the more credibly we can present our case
Three sets of relationships
The easy bits
1. Wealthy people (and countries) can make healthier choices
2. Greater wealth provides more money to spend on health systems (if you chose to do so)

Does better health increase wealth and/or reduce future health care costs?
?
?
Some basics: How can we conceptualise “economic costs and benefits”?
1) Health care costs2) Productivity costs
a) Microeconomic costsb) Macroeconomic costs
3) Costs of losing the value of years of life4) Public-policy relevant and irrelevant costs
1) Health care costs
• Does improved health reduce health care costs? (or, put another way)
• Does ill health increase health care costs?)

However…
• Those with unhealthy lives may cost more each year, but they live for fewer years
• What is the cost of the extra years lived by those who are healthy?
How improved health could affect lifetime health care costs?
Less disease and disability at a given point in time, for a given population, or at a given age
DECREASE
Additional life years INCREASE
Higher long term care costs of dying at older ages
INCREASE
Bottom line effect ??
Lower acute health care costs of dying at older ages
DECREASE
Return on investment (US data)
• Investment of US$10 per person per year for ‘proven community-based disease prevention programs (on) physical activity, nutrition, and (reducing tobacco use can lead to reductions of:– type 2 diabetes and high blood pressure by 5% in 1 to 2 years;– heart disease, kidney disease and stroke by 5% in 5 years; and– some forms of cancer, COPD and arthritis by 2.5% in 10 to 20
years.
• This yields net savings of almost US$18 annually, a return on investment of 6.2 for every US$1 invested.

Fortunately, saving health care costs is not a sensible criterion for judging the true economic value of health!
2) Productivity costs
a) Microeconomicb) Macroeconomic
More relevant economic cost categories… …but challenging to assess empirically

Productivity costs: microeconomic
Commission on Macroeconomics and Health
• Better health promotes economic growth in poor countries
Physical work is much less important in generating wealth
High and middle income countries are different
The impact of health on productivity (proxied by wages and earnings)
• US (1967): People in poor health earned 6.2% less than those in good health– Differential effects
• Black males more likely to drop out of labour force or cut hours
• White males more likely to cut hourly rates
• US (1974): people at age around 50 earn 20-30% less if certain diseases in past 10 years– Effects vary according to disease
• US (1967-77): older people earn 20% less if illness in past 10 years
The impact of health on wages and earnings
• UK (2004): People in excellent (vs less than excellent) health increases hourly wages by ~ £1
• Sweden (2000): Women with work absence due to own health problem have significantly lower wages, while for child’s illness have no such loss.
• US (2004): Impact of serious illness in men greatest when in 40s, but for women if in 30s
• US (1986): Episode of mental illness reduces wages by 24% and effect persists for at least 15 years
The impact of health on labour supply
• Ireland (2003): Those with chronic illness or disability “severely” hampering daily activities less likely to work:– Men 61% less– Women 52% less
• Germany (1998): Suffering a “health shock” reduced probability of working in subsequent years– 5.3% less in next year– 17.5% less after 2 years
The impact of health on labour supply
• Early retirement– Those in poor health tend to retire 1-3 years
earlier– Long term health problem beginning at 55
reduced age at retirement by 2.8 years– Heart attack or stroke affecting daily activities
after age 50 increased probability of early retirement by 42%
Impact of health on education
• Human capital theory predicts that more educated individuals will be more productive, and obtain higher earnings
• Children with better health will have less absenteeism and lower dropout rate
• This is confirmed in low income countries– Deworming, iron supplementation, supplementary
nutrition all increase attendance• Less work in high income countries
Research from high income countries• Very good or better health in childhood associated with a third of a
year more in school• Major Illness before age 21 decreased education on average by 1.4
years.• negative effect on educational outcomes of smoking or poor
nutrition greater than that of alcohol consumption or drug use.• Signifi cant positive impact of physical exercise on academic
performance.• Obesity and overweight negatively associated with educational
outcomes.• Sleeping disorders hinder academic performance.• Very little research on effect of anxiety and depression• Asthma does not seem to affect school performance.
The impact of health on labour supply of carers
• Men caring for sick wives likely to leave labour force
• Women caring for sick husbands more likely to join labour force
30
Impact of health on savings
• Theory predicts that improved health will increase savings (which are needed for investment in economy)
• Individuals have greater probability of reaching retirement and so will save for this
• This is confirmed in low income countries• Insufficient evidence from high income
countries
A quantitative example: Health & retirement in Europe
• European Community Household panel, eight waves (1994-2001), nine EU countries (older workers)
• Dependent variable: retirement (self-reported as such and all departures from labour force)
• Explanatory variables:– Health stock (composite measure indicating health relative to
someone of same age)
– Health shock (acute deterioration in health)
– Income / wealth, education, demographics (gender, cohabit, children at home)
Self-reported “retirement”
All departures from labour force
Health stock -13% -17%
Health shock:
small 0% +14%
medium +44% +50%
large +47% +106%
A one-unit change in the health measure leads to a change in the probability of retiring by x%

The historical contribution of health to economic development
• Current levels of economic wealth in today’s high-income countries are to a substantial degree explained by past achievements in health
• 30% of income growth in UK between 1780 and 1980 due to better health & nutrition (Fogel, 1997)
• Similar findings of past century in 10 industrialised countries (Arora, 2001)
A quantitative example:CVD and economic growth
• 26 high-income countries• 1960-2000 in 5-year intervals• Dependent variable: per capita income• Explanatory variables:
– Initial income per capita– Secondary schooling– Openness of the economy– Health proxy:
cardiovascular disease mortality rate at working age
“A ten percent increase in CVD mortality rate among the working age population decreases the per capita income growth rate by about one percentage point.”
Source: Suhrcke/Urban 2009
The potential for longevity gains to increase labour force participation and the working
age population1) However, much depends on when people retire
2) What if “working age” – typically defined as age 15-64 – increased in line with longevity gains?

3) “value of life” costs
• Costs of ill health through life foregone exceed any of the narrow cost concepts presented so far!
Health care costs
Productivity costs
Value of life costs
• How much do people value health & life? How to measure such non-market goods?
The value of a statistical life
• Oil platform workers and miners have an increased risk of death
• The probability of losing x years of life can be determined
• They are paid more (£y) to compensate for this
• Value of a statistical life = £y/x

4) Public-policy relevant and public-policy irrelevant costs
• When do “costs” justify public policy intervention?

“If people want to be fat, smell like ashtrays and die early, let them.”

Can health systems promote economic development?
?
There are different ways of spending money
• Issue a single call for tenders, for the whole thing (construction, furniture, technology ….)– A handful of global companies have the capacity to bid– In fact, they can probably lift the bid documents off the shelf– Profits will be repatriated, supplies will be sourced from abroad,
and local economy will get little benefit– If project fails, contractor will walk away
• Divide project into smaller tranches– Local small and medium enterprises can bid– Local employment will increase– Health of local population will improve– Contractors will be there when you need them 51
• So you want to build a new hospital?
Health systems wealth
Investment in health facilities in deprived areas can be a critical factor in facilitating inward investment
A key issue for EU structural funds
Investing in growth?
• Olivier Blanchard, Chief Economist of the IMF has recalculated the fiscal multiplier – the impact of additional spending on GDP growth
• Larger than previously thought – about 1.6• So maybe increased government spending
would actually make things better?
Where should we invest?
