Abstract

A szerző igyekszik bebizonyítani, hogy a végtelen időhorizonton racionálisan viselkedő bankok számára az ügyfél-információk teljes megosztása, az úgynevezett teljes lista a legelőnyösebb, tehát a legnagyobb várható profitot eredményező megoldás abban az esetben, ha a banki népességen belül magas a rossz adósok aránya, a jó adósok csökkenő valószínűséggel fizetik vissza a hitelt, valamint a bankok egymástól jelentősen eltérő határköltségekkel működnek. A teljes listából fakadó előnyök további előfeltétele, hogy minden bank megossza összes ügyfél-információját, valamint az információk megbízhatók legyenek. Amíg azonban a rossz ügyfelek részaránya alacsony, vagy a bankok határköltségei között nincsenek számottevő különbségek, a bankok domináns stratégiája az lesz, hogy nem osztják meg egymás között az ügyfél-információkat. A jó, a hiteleiket időben törlesztő ügyfelek számára azonban mind a teljes információmegosztás, mind az információmegosztás hiánya kedvezőtlenebb, mint az úgynevezett negatív lista, mert az előbbi esetekben magasabb kamatlábat fizetnek, mint negatív információmegosztás mellett. Journal of Economic Literature (JEL) kód: D81, D82, D92, G21, G29.
