La « finance comportementale »: un état des lieux

Nihat Aktas

Reflets et perspectives de la vie économique, 2004, vol. XLIII, issue 2, 19-33

Abstract: After a detailed exposition of the behavioral underpinnings of the standard version of the EMH, this contribution is aiming at characterizing the specificities of « behavioral finance». This new area is explicitly taking into consideration the existence of « noise traders», i.e. market participants who are making decisions based on beliefs and emotions rather than on « rational» valuation based on economic fundamentals. They therefore cause inefficiencies in the pricing system, due to the costs and risks borne by rational « arbitrageurs» who are striving to bring prices back to the fundamental value.
