Hayat dışı sigorta riskinin toplamsal hasar rezervi yöntemi ile analizi : Türkiye uygulaması

Year 2019, Volume: 12 Issue: 1, 32 - 42, 28.06.2019

Abstract

Hasar gelişim sonucu, zaman içerisinde hasar
rezervlerindeki değişimdir ve bir sigorta şirketinin kar-zarar tablosundaki
temel risk etkenlerinden birisidir. Bu çalışmada, Türkiye’de zorunlu trafik sigortası
branşında hizmet veren bir sigorta şirketinin 2007-2013 yılları arasındaki
verileri kulanılarak; sigorta şirketine dair hasar gelişim sonuçları, gelecek 1
yıllık ve çok yıllık rezerv ve prim riski toplamsal hasar rezervi yöntemi ile
hesaplanmıştır. Geleceğe dair prim tahminleri doğrusal ve doğrusal olmayan regresyon
yöntemleri kullanılarak elde edildi. Rezerv riski her iki yöntem için aynı
kalırken, doğrusal olmayan regresyon yönteminde prim riski artmıştır.

Analysis of non-life insurance risk in the additive loss reserving model : An application to Turkey

Year 2019, Volume: 12 Issue: 1, 32 - 42, 28.06.2019

Abstract

Claims
development results are the changes in claims reserves and one of the major risk
drivers in the profit and loss statement of a general insurance company, In
this study, claims development result, future one year and multi-year reserve
and premium risk computed with additive loss reserving model using data of an
insurance company serving in the mandatory traffic insurance for the 2007-2013
periods. The estimators of premiums were calculated by using linear and
non-linear regression methods. In conclusion, the reserve risk is same for two
methods, but premium risk is increased for the non-linear regression method .
