SİGORTA ŞİRKETLERİNİN STOKASTİK SINIR ANALİZİ İLE ETKİNLİĞİ: BİR META ANALİZ

Öz

Çalışmanın amacı, Stokastik Sınır Analizi (SSA) ile sigorta şirketlerinin maliyet etkinliğini hesaplayan çalışmaları meta analiz ile değerlendirmektir. Meta analiz, PRISMA yönergeleri doğrultusunda gerçekleştirilmiştir. 01.06.2024 tarihinde Web of Science, Scopus ve Google Scholar kullanılarak tarama yapılmıştır. Meta analiz için Jamovi istatistik yazılımı kullanılmıştır. Bu çalışmada incelenen çalışmalar arasında yüksek heterojenlik ortaya çıkmıştır. Yüksek heterojenlik farklı çalışmaların örneklemleri, örneklem büyüklükleri, değişkenleri, dağılımları ve sonuçları arasında önemli farklılıklar olduğunun göstergesidir. Örneklemi yüksek gelir grubunda olan ülkelerde maliyet etkinliği yüksek olma eğilimindedir. Yazında sigorta şirketlerinin maliyet etkinliğini ölçen çalışma sayısı azdır. Konu ile ilgili çalışma sayısının artması çalışmalar arasında karşılaştırma yapmayı kolaylaştıracaktır. Yöneticiler ve politika yapıcılar şirketlerin maliyet etkinliğinin artması için ülke politikalarını ve yasal düzenlemeleri gözden geçirmelidir.

EFFICIENCY OF INSURANCE COMPANIES WITH STOCHASTIC FRONTIER ANALYSIS: A META ANALYSIS

Öz

This study aims to evaluate the studies calculating the cost effectiveness of insurance companies using Stochastic Frontier Analysis (SFA) through a meta-analysis. The meta-analysis was conducted in accordance with PRISMA guidelines. The search was performed on 01.06.2024, using Web of Science, Scopus and Google Scholar. Jamovi statistical software was employed for meta-analysis. High heterogeneity was identified among the examined studies, indicating significant differences in samples, sample sizes, variables, distributions and results. Cost effectiveness tends to be higher in countries with high-income sample groups. There is a dearth of studies measuring the cost effectiveness of insurance companies in the relevant literature. Increasing the number of studies on this subject will facilitate comparison between studies. Managers and policy makers should review country policies and legal regulations to enhance the cost effectiveness of companies.
