Abstract

Tanulmányunkban a hálózatelmélet segítségével a bankok vállalati ügyfélportfóliójára vonatkozó ügyfélelvándorlás jelenségét modellezzük. Valós adatok hiányában először egy többszereplős bankpiac vállalati ügyfelei által alkotott hálózatot generálunk. A hálózat csomópontjai maguk a vállalatok, a vállalat banki hovatartozása a csomópont egy belső koordinátájának felel meg. Az irányított éleken a vállalatok közötti - a vállalat saját bankján vagy más bankon keresztül lebonyolított - átutalások zajlanak. A generált hálózat alapján vizsgálatunk középpontjában a bankválasztási stratégia egyensúlyi tulajdonságai és az ügyfélelvándorlás jelensége áll. Modellünkben - a neoklasszikus egyensúlyelmélet egyik fő állításával ellentétben - a piaci egyensúly nem egyértelmű, több egyensúlyi állapot alakulhat ki. Az ügyfélelvándorlás modellezése során azt tapasztaltuk, hogy a vállalati ügyfelek hálózatában az esetek háromnegyed részében nincs újabb elvándorló ügyfél. A legrosszabb esetben jelentős elvándorlási hullámok is kialakulnak. Végezetül arra kerestünk választ, hogy az ügyfélelvándorlás szempontjából kulcsfontosságú vállalatok milyen topológiai tulajdonsággal jellemezhetők. Megállapítjuk, hogy az ügyfélelvándorlás szempontjából kulcsfontosságú vállalatokat nem minden esetben jellemzi partnereinek száma.
