Abstract

Serbian: Еквивалентни број као реципрочна вредност Хиршман-Херфиндаловог индекса концентрације полазна је основа за формулисање индекса монополисаности тржишта, који показује нормализовану разлику између стварног и ефективног броја учесника на тржишту. Теоријско разматрање овог индекса илустровано је примером обрачуна степена монополисаности тржишта осигурања у Србији (без Косова и Метохије) у периоду 2010–2022. English: The numberс-equivalent as the reciprocal value of the Hirschman-Herfindahl concentration index is the starting point for formulating the market monopolization index, which shows the normalized difference between the real and effective number of market participants. The theoretical consideration of this index is illustrated by an example of calculating the degree of monopolization of the insurance market in Serbia (without Kosovo and Metohija) in the period 2010-2022.
