Abstract

Analiza obavijanja podataka (DEA) je prvi put predstavljena u svrhu evaluacije efikasnosti neprofitnih jedinica. U ovom radu, proširena DEA-Window Analiza korišćena je za procenu efikasnosti banaka u Srbiji na osnovu panel podataka za period od 2005-2011. godine. Ova analiza omogućava praćenje trenda efikasnosti i rangiranje svake banke na osnovu evaluacije sa profitnog i operativnog aspekta. Osim toga, dobijeni rezultati omogućavaju analizu kretanja efikasnosti celokupnog bankarskog sektora.
