Abstract

A 20. század végi elméleti közgazdaságtan egyik kiemelkedő kutatási területe a hatékony piacok elmélete, amely a hetvenes évektől kezdve vált a pénzügyi közgazdaságtan megkerülhetetlen részévé. Már a nyolcvanas évek közepétől azonban támadások, empirikus cáfolatok érték e tant, amely a kilencvenes években szinte divattá vált a nemzetközi mainstream pénzügyi kutatók körében. Nagyrészt bizonyítottá vált, hogy a tőkepiacok nem mindig felelnek meg az információs hatékonyság kritériumainak. Ezt a kérdést kutató pénzügyi tanulmányokból mára szerteágazó szakirodalom született pénzügyi viselkedéstan (behavioral finance) néven. A szerző a fenti két irányzat elméleti hátterét mutatja be, majd a pénzügyi viselkedéstant foglalja egységes keretbe, és végül megvizsgálja az elméleti és gyakorlati relevanciájukat.
