Investing in Health EU Conference Gastein, October 2 nd, 2003 Mukesh Chawla, Ph.D The World Bank

The Health and Growth Relationship Well-established Causality runs both ways Higher incomes facilitate access to goods and services – like nutritious diet, safe water, quality health care - that promote health and longevity Nutrition and health promote long-term growth

How Health Affects Growth Good health enhances worker productivity by raising physical and mental capacity as well as cognitive functioning and reasoning ability Health improvements facilitate labor market participation, worker productivity, investments in human capital, savings, fertility and population age structure Health improvements influence income growth through effect on labor market participation, enhanced worker productivity, investments in human capital, etc.

The Evidence At the microeconomic level, positive relationship between health and productivity of workers (see, for example, Schultz 1999, 2002) At the macro level, positive and significant effect of health on worker productivity (Bloom et al, 2003) Strong correlation between aggregate health measures (life expectancy, etc.) and per capita income (The World Bank)

The Evidence Several studies show that life expectancy has a significant, sizeable and positive influence on economic growth (Barro 1996, Bhargava et al 2001, Easterly and Levine 1997, Sachs 2000) Large part (33% per annum) of British economic growth during was due to increase in nutrition (Fogel 1997) Improved health increased labor availability in Korea by 1% a year or more during (Sohn 2000)

Commission on Macroeconomics and Health (CMH) CMH research finds that the economic impact of ill health on individuals and societies is far greater than previous estimates. Providing basic health care to the world's poor is technically feasible and cost effective Potential saving of 8 million lives annually Fuel development by generating hundreds of billions of dollars in new economic activity every year

Health and Poverty Trap Poverty creates disease and disease creates poverty (Prof. Daniel Cohen, Ecole normale superieure, Paris, France) Ill health disproportionately afflicts poor people, and imposes a higher level of risk on the poor The poor are more exposed to diseases, and they often work mostly in physically demanding jobs in unsafe conditions “ The body is poor people ’ s main asset, but one without insurance ” (The World Bank)

Health and Poverty Trap Huge gap between rich and poor in access to health services Illness most frequently cited by the newly poor as the cause of their slide A wage earner ’ s illness can push families over the edge into poverty, and poor families into destitution. For women in particular, poor reproductive health is a source of insecurity and a major factor in their poverty.

The Debilitating Effect of Diseases Approximately one-thirds of world ’ s population infected by tuberculosis: annual economic costs to the poor: US$12 billion (WHO 2001) Countries with high malaria transmission averaged only 0.4% growth per annum compared to 2.3% in other countries ( )

The Debilitating Effect of Diseases Potential effect of an HIV-AIDS epidemic among economically active population in Eastern and Central European countries: annual decline in economic growth of 0.5 to 1% (The World Bank 2003) Neuropsychiatric disorders will account for 15% of the global burden of disease by 2020 Mental illness impairs productivity and adversely affects the formation of human capital

$ billion Direct Costs of Diabetes in the USA (Source: Barnes 2003, presentation at the PCU Conference in Lithuania, September 2003)

Total direct and indirect cost of diabetes in USA – US$98.2 billion (1997) (Source: Barnes 2003, presentation at the PCU Conference in Lithuania, September 2003) $24,6 $7,7 $11,8 $37,1 $17,0 Mortality – cost of productivity loss Handicap Chronic complications Acute complications Cost of general medical service

Direct Costs of Diabetes in Europe (Source: Barnes 2003, presentation at the PCU Conference in Lithuania, September 2003) CountryTotal per-patient cost (Euros, 1999) Belgium3,295 France3,064 Germany3,576 Italy2,991 Netherlands1,827 Spain1,305 Sweden2,630 UK2,214

Work disability accounts for most of the indirect cost of diabetes Diabetes patients more likely to stop working entirely and to take early retirement (Yassin et al., 2002, Olsson et al., 1994) Early death of diabetes patients accounts for one-third of the indirect cost of diabetes in the U.S. (ADA 1997) and 22% in Sweden (Henriksson and J ö nsson, 1998) Indirect Costs of Diabetes Exceed Direct Costs (Source: Barnes 2003, presentation at the PCU Conference in Lithuania, September 2003)

Conclusions Widespread evidence of long-term causal inter-relationship between health and worker productivity “ Health improvements influence the pace of income growth via their effects on labor market participation, worker productivity, investments in human capital, savings, fertility and population age structure ” (Bloom, Canning and Sevilla, 2003)

Conclusions Strong case for justifying public expenditures on health as an investment Focus on the health of the poor will yield rapid and significant dividends Top priority to the prevention and treatment of HIV infections and tuberculosis

Conclusions “ Working together for health is not just a matter of charity, it also makes economic sense. ” - UN Secretary-General Kofi Annan, addressing the World Economic Forum in New York in February 2003
