Risk alma davranışı: davranışsal iktisat açısından bir gözden geçirme

Öz

ABD emlak piyasası kaynaklı 2008 finansal krizinin etkileri sürerken, davranışsal iktisat yazınında finansal kararların rasyonelliğini etkileyen bilişsel sapmalara yönelik ilgi katlanarak artmıştır. Özellikle risk algısında ve risklerin gerçekçi değerlendirilmesinde sapmaların, krizin ortaya çıkışında önemli rol oynadığı bilinmektedir. Bu gözden geçirme çalışması, von Neuman ve Morgenstein’ın beklenen fayda teorisini ortaya atışından bu yana belirsizlik altında risk içeren kararların alınması konusunda davranış deneyleri bulgularını ele almaktadır. Risk alma davranışında tespit edilen bilişsel sapmalar ilişkin deneylerin sonuçlarıyla birlikte değerlendirilmekte, bu sonuçların sosyal bilimler dışında diğer disiplinler için de erişilebilinir bir şekilde ve olabildiğince kapsamlı olarak sunulması amaçlanmaktadır
