Belirsizlik Altında Tercihler ve Beklenen Fayda Modelinin Yetersizlikleri

İktisatta belirsizlik altındaki tercihleri açıklayan hakim çerçeve Beklenen Fayda teorisidir. Yaygın olarak kullanılmasına rağmen, Beklenen Fayda teorisi sorunsuz değildir. Yapılan deneysel ve ampirik çalışmalar, gerçek hayatta bireylerin riskli alternatifler arasında yaptıkları tercihlerin Beklenen Fayda teorisinin aksiyomları ile çeliştiğini göstermektedir. Bu çalışmada deneysel çalışmalardan elde edilen bulgular ışığında, Beklenen Fayda teorisinin bireylerin belirsizlik altındaki tercihlerini açıklama konusundaki yetersizlikleri incelenmiştir.

Preferences Under Uncertainty and the Deficiencies of the Expected Utility Model

In economics, the prevailing framework to explain preferences under uncerta- inty is the Expected Utility theory. Despite its widespread use, the Expected Utility theory is not free from problems. Experimental and empirical works shows that, in real life, the choices of individuals among risky alternatives conflict with the axioms of the Expected Utility theory. This study, in the light of experimental studies, investigates the problems with the Expected Utility theory regarding the individuals’ preferences under risk.
