Research Paper (postgraduate) from the year 2015 in the subject Economy - Health Economics, Tongji University (Sino-Germany College), language: English, abstract: This paper uses basic educational and health-related factors as antecedents for life expectancy at birth on country level. Life expectancy is a highly complicated construct and varies strongly with respect to national borders. Aiming to provide a prediction model, prognoses are based on health expenditure per capita, HIV prevalence, immunization rates and literacy rates and justify cross-national dissimilarities in expected lifetime in a simple manner. The model helps to estimate the importance of the used antecedents among each other and gives a basic understanding on how life expectancy could potentially be influenced. Due to the usage of basic antecedents, the highlighted potential will be of special interest for developing countries.
