The discussion between the researchers have not been resolved. This lack of agreement and the simplifying assumptions behind both approaches prevented their integration in the practical toolkit of demographic analysis. This paper shows that both methods are useful in drastically reducing the estimation errors in life expectancy. The disputes were largely due to inconsistent inputs rather than methodological contradictions. Furthermore, the methods produce by far better results as compared to the popular alternative, the extrapolation of the death rates. In combination the two alternative methods may even lead to a better outcome. date: 2016-08-07 publisher: WP-16-010 creators_browse_id: 76 full_text_status: public monograph_type: working_paper place_of_pub: IIASA, Laxenburg, Austria projects: Reassessing Ageing from a Population Perspective (RE-AGEING, FP7 323947) coversheets_dirty: FALSE fp7_project: yes fp7_project_id: info:eu-repo/grantAgreement/EC/FP7/323947/EU/Reassessing Ageing from a Population Perspective/RE-AGEING fp7_type: info:eu-repo/semantics/book access_rights: info:eu-repo/semantics/openAccess citation: Ediev, D.
