This study is concerned with understanding the factors of life expectancy in Turkey for the period 1965-2005. The determinants of life expectancy in Turkey are related to selected social, economical and environmental factors. Bounds testing approach to cointegration is employed to compute the long-run elasticities of longevity with respect to the selected economic, social and environmental factors. There exists no previous study that estimates empirically the determinants of life expectancy in Turkey on the basis of time series data and cointegration framework. Empirical results suggest that nutrition and food availability along with health expenditures are the main positive factors for improving longevity whereas smoking seems to be the main cause for mortality. The results also draw a number of policy recommendations for improving longevity. (C) 2011 Elsevier B.V. All rights reserved.
