Bu çalışmada, açığa çıkarılan tercih teorisi aksiyomlarının geçerliliği parametrik olmayan yöntemler kullanılarak deneysel veriler üzerinden test edilmiştir. Farklı fiyat ve miktar senaryoları altında oluşturulan deney düzeneğinde tercih yapılarının belirlenebilmesi için deneklerden öncelikle iki adet mal ve sonrasında çok mallı durumu temsilen sekiz farklı mal arasından farklı bütçeler altında seçim yapmaları istenmiştir. Elde edilen deney sonuçları hem iki mallı hem de çok mallı durum için, deneye katılıp deney sonucu elde edilen toplamda 107 kişiden tamamının, GARP dolayısıyla WARP ve SARP aksiyomlarını sağladığını göstermektedir. Dolayısıyla bu sonuç, deneklerin tamamının tercihlerinin açığa çıkarılan tercih teorisi ile tutarlı olduğunu ve deneklerin rasyonel tercihlerde bulunduğunu göstermektedir.

Revealed Preferences Theory: An Experimental Approach

Öz

In this study, the validity of the revealed preference axioms is tested by experimental data using non-parametric methods. In the experimental setup established to determine the preference structures of the consumers under different price and quantity scenarios, the subjects are asked to choose between two goods first and then eight different goods representing the multi-goods situation under different budgets. The results of the experiments show that, for both scenarios, all of the 107 people who participated in the experiment provided the GARP axiom and the WARP and SARP axioms. This result indicates that the preferences of all subjects consistent with the revealed preferences theory, which means that the subjects have rational preferences.
