Effect of Turkish mortality developments on the expected lifetime and annuity using entropy measure

Over the past three centuries, there has been a steady and gradual decline in mortality rates due to a considerable process of eliminating hazards to survival, which have increased the life expectancy at birth remarkably. The improvements in mortality rates often been underestimated by annuity and pension providers. To measure the effect of mortality rate developments on life expectancy or annuity, many demographers use the idea of entropy. We use the entropy measure to explain the effect of any change in mortality rates on the annuity along with Gompertz's mathematical model for the force of mortality to obtain a more theoretically satisfactory conclusion. Entropy measures for the Turkish life table are calculated for different age, year, discount factor, and gender parameters.

Assessment of Longevity Risk on PensionFunds: Credibility Approach
Yıldırım Külekci, Bükre (null; 2019-10-28)
Over the last 100 years, there has been a steady decline in mortality rates. With the unexpected decrease in death rates; variability in the age of death declined and deaths are concentrated to the older years of life, therefore, causing deficits in the pooled funds of insurance and pension providers, which are built upon the underestimated rates. To correctly measure the effect of mortality rates on the financial stability of these providers, longevity risk should be taken seriously. This study aims to inv...
Determining the role of mutation load in mammalian senescence
Somel, Mehmet; Özer, Füsun; Turan, Zeliha Gözde; Koptekin, Dilek; Ghalichi, Ayshin(2016-12-31)
In most multicellular species, aging is accompanied by an increasing risk of disease and mortality, a process termed senescence. The evolutionary causes and genetic bases of senescence are little understood. Senescence is usually associated with accumulating cellular damage, although a number of theories suggest that harmful mutations that are expressed only at late age could also contribute to the aging phenotype. Analyzing primate brain transcriptome data, we recently identified a pattern that would suppo...
Modelling and forecasting age-segmented mortality: evaluation of lLe-Carter method and its extensions
Alşan Kılıç, Raife Sıda; Sürücü, Barış; Department of Statistics (2019)
Mortality dynamics deal with the human mortality from birth to death giving insights for the population in different aspects; age, year, gender and enable to ascertain crucial mortality trends as well. Over the last decades, ample new methods have been developed and the mortality modelling has been evolved into more effective ways. Among these models, the pioneering and the most seminal one is Lee-Carter model (Lee & Carter, 1992). From its development, Lee-Carter model has been intensively studied and its ...
The Estimation of adopted mortality and morbidity rates using markov model and phase type law: Turkish case
Akat, Fulya; Kestel, Sevtap Ayşe; Department of Financial Mathematics (2015)
Mortality estimation has an important role in determining future population structures and making economical decisions. However, mortality measures do not provide sufficient information about populations. Because of this reason, morbidity estimation of chronic diseases and disabilities has become more important. In this study, firstly Turkish Mortality Tables, such as TRSH 2010, TRH 2010 and SGK 2008, and CSO1980 are adopted to Markov Model to determine mortality rates with respect to phase type distributio...
Kentsel Mekân Örgütlenmesinin Yaşlıların Kentsel Etkinlikleri Üzerindeki Etkisi, İstanbul ve Viyana Örneği
Köse, Neşe ; Çolpan Erkan, Nilgün (Middle East Technical University, Faculty of Architecture, 2014-6-1)
Improved quality in technological and medical services have resulted in an increase in the number of elderly people within the average population. Concordantly , the demands and desires of the elderly population have gained significance. Standards that consider elderly people’s needs in their living environments have become one of the primary topics of discussion. Today, behind the global-scale transformation of the concept of old age and perception towards elderly people lies modernism (including industria...
