OUTLINE OF PRESENTATIONINTRODUCTION THE PROBLEM OBJECTIVES OF THE STUDY DATA & METHODSRESULTS & DISCUSSION POLICY IMPLICATIONS REFERENCES
INTRODUCTION Health is an indicator of development and the
mechanism for achieving development (Buor, 2008).
Strong health systems are fundamental to improving health outcomes and accelerate progress towards health-related MDGs (Sen, 1999; WHO, 2009).
The enjoyment of the highest attainable standard of health is fundamental right of every human being (WHO/UN, 2000; Human Right Council, 2002).
THE PROBLEMHigher government expenditure on human
health creates three-tier-benefit (Barro, 1996).
Increasing life expectancy at birth by 10% increases economic growth rate by 0.35% a year (Comm. Macroeconomics & Health, 2001).
Studies are conducted to argue this relationship.
THE PROBLEM CONT’D
To see health expenditure-health status relationship, studies are not comprehensive, eg. Castro-Leal (2000), Anyanwu and Erhijakpor (2007), Buor (2008).
Is there any linkages between health care spending and health status in West Africa?
OBJECTIVES OF THE STUDY
To estimate the long-run relationship between health care expenditure and health status.
To estimate the short-run relationship between health care expenditure and health status in West Africa.
DATA & METHODS
• Time series data of three variables from 1990 to 2010 were used:
- Health status Index - Health expenditure- Literacy rateHealth expenditure and literacy rate were
extracted from World Bank WDI online Database, June 2012
DATA & METHODS
Health status index was constructed from 10 health indicator measures using principal component Analysis(PCA)
- Prevalence of HIV, total (% of population ages 15-49)-HIV- Births attended by skilled health staff (% of total)-BASK- Contraceptive prevalence (% of women ages 15-49)-CONT- Immunization, measles (% of children ages 12-23 months)-
IMM - Improved sanitation facilities (% of population with access)-ISF- Improved water source (% of population with access) -IWS- Life expectancy at birth, total (years) -LEB- Malaria cases reported -MAL- Maternal mortality ratio (national estimate, per 100,000 live
births)-MMR - Pregnant women receiving prenatal care (%) -PWPC
DATA & METHOD CONT’D• Eigenvector with lager eigenvalue was used to
construct the index. All components used explained above 60% of the variation in HSI.

TIME SERIES PROPERTIES OF THE DATA
There are many different unit root test used in the literature, however we use two most commonly used test
• Augmented Dickey Fuller test (ADF)• Phillips and Perron test (PP) The results of both tests indicate that all the
variables are of I(1). Under such circumstance Johansen Multivariate Cointegration approach is appropriate.
• The Multivariate Cointegration approach is base on error correction representation of the p order Vector Autoregressive model with Gaussian error
• Where is the first difference operator, is coefficient matrix representing short-run dynamics
is Rank and is nxn matrix, is error term
Two different likelihood ratio tests were developed by Johansen for testingthe number of Cointegration vectors (r): the trace test and maximum eigene value
test given respectively by and

POLICY IMPLICATIONS
Governments should be committed to increase health care spending in West Africa.
General health education and awareness should be prioritised in West Africa.
As closer look should be taken to see weather health care resources are channelled to areas meant for.
