Koncentracija u sektoru osiguranja u Srbiji: promene u periodu 2011–2020. i njihova dekompozicija (Concentration in Serbian Insurance Sector: 2011–2020 Changes and Their Decomposition)

Abstract

 Serbian Abstract: U radu se analizira koncentracija u sektoru osiguranja i uticaj strukture tržišta (rasporeda tržišnih udela) i broja osiguravajućih društava na stepen koncentracije (i konkurencije) u sektoru osiguranja u Srbiji (bez Kosova i Metohije) u desetogodišnjem periodu od 2011. do 2020. godine. Kao osnov za analizu poslužio je obračun većeg broja odgovarajućih koeficijenata koncentracije, na osnovu ukupne premije osiguranja, koji su pokazali relativno visok stepen koncentracije, ali bez jasne tendencije u njegovom kretanju. Razgraničenje uticaja navedenih faktora izvršeno je na osnovu dekompozicije indeksa Hana-Keja na dve komponente, u kojima figurišu navedeni faktori. Dekompozicijom je objašnjen najveći deo varijacija u stepenu koncentracije u svim posmatranim godinama (iznad 87,5% kao minimuma), a koje su prevashodno bile pod uticajem tržišne strukture (promena tržišnih udela) s kojom postoji pozitivna iako i umerena korelacija, ali ne i što se tiče broja osiguravajućih društava, s kojim su ostvarena divergentna i gotovo potpuno nekorelisana kretanja.

English Abstract: This paper analyses the concentration in the insurance sector and the impact of the market structure (distribution of market shares) and the number of insurance companies on the level of concentration (and competition) in the insurance sector in Serbia (excluding Kosovo and Metohija) in the ten-year period, from 2011 to 2020. The analysis relies upon a stated number of relevant concentration coefficients, based on the total insurance premium, showing a relatively high degree of concentration but without clear fluctuation tendencies. The differentiation of the impact of the mentioned factors was done on the basis of the decomposition of the Hannah-Kay index into two components, figuring the mentioned factors. Decomposition explained most of the degree variations concentration in all observed years (above 87.5%, at a minimum), primarily affected by market structure (changed market share) with a positive, though moderate, correlation; the result was quite different when it came to the number of insurance companies, where divergent and almost completely uncorrelated fluctuations were recorded.
