DEKOMPOZICIJA GINIJEVOG KOEFICIJENTA NEJEDNAKOSTI POMOĆU SHAPLEYEVE VRIJEDNOSTI: PRIMJER HRVATSKE. (Bosnian)

This paper contributes to the Croatian literature on the decomposition of Gini coefficient, by examining the use of Shapley value from the cooperative game theory. Decomposition is conducted for different groups of households (depending on the degree of urbanization of the place of residence, and number of breadwinners in the household) and income components, based on the data from the Croatian Statistics on Income and Living Conditions (SILC). It also examines the impact of the fiscal system on reducing inequality. The results show that households in rural areas and those with one breadwinner are major contributors to income inequality, while the decomposition of inequality by income components largely confirmed previous research that income tax and social security contributions, as fiscal policy instruments, reduce inequality. Based on the results obtained, the paper also provides some guidelines for policy makers. [ABSTRACT FROM AUTHOR]

Ovaj rad je doprinos hrvatskoj literaturi dekompozicije Ginijevog koeficijenta nejednakosti, u kojem se ispituje primjerenost upotrebe Shapleyeve vrijednosti iz kooperativne teorije igara. Dekompozicija uključuje podjelu na različite grupe kućanstava (ovisno o stupnju urbanizacije prebivališta i broju hranitelja u kućanstvu) i dohodovne sastavnice, a temelji se na podatcima iz Ankete o dohotku stanovništva. Također se ispituje utjecaj fiskalnog sustava na smanjenje nejednakosti. Rezultati rada ukazuju da kućanstva u ruralnim područjima i jednohraniteljska kućanstva najviše doprinose dohodovnoj nejednakosti, dok je dekompozicija nejednakosti po dohodovnim sastavnicama uglavnom potvrdila prijašnja istraživanja o tome koji instrumenti fiskalnog sustava smanjuju nejednakost - porez na dohodak i doprinosi za socijalno osiguranje. Na temelju dobivenih rezultata, rad pruža i smjernice za kreatore javnih politika. [ABSTRACT FROM AUTHOR]
