Abstract

Yeni
Keynesyen ekonomistler fiyat katılıklarının nasıl ortaya çıktığı konusundaki
çalışmalarını özellikle mikro temellere dayandırırlar. Sims (2003), bu
modellerden biri olan “Rasyonel Dikkatsizlik” (Rational Inattention) modeli ile
fiyatların belirlenmesi sürecini ele almıştır. 
Modelde, bütün bilgi kamuya açık ve erişilebilir olması durumunda bile
ajanlar bilgiyi değerlendirme kısıtlarından ötürü, verecekleri kararlarda
bilginin tamamını kullanamazlar. Ancak bilginin hangi kısmını işleyeceklerine
ve hangi bilgiye dikkat edeceklerine kendileri karar verirler. Bu çalışmada kullanılan
“Rasyonel Dikkatsizlik” modeli ile Türkiye’deki ekonomik ajanların makroekonomik
şoklara mı yoksa sektöre özgü şoklara mı daha çabuk ve etkili tepki verdikleri
araştırılmaktadır.

Rational Inattention Model and Price Rigidities

Abstract

New Keynesian economists base their work on the emergence of price rigidities especially on micro-level. Sims (2003)’s "Rational Inattention" model is one of these models that deals with the process of pricing mechanism. In this model, even though all information is available to the public, they cannot use all the information in decisions they make. However, they decide which part of the information they will process and which information they will pay attention to. The "Rational Attention" model used in this study investigates whether economic agents in Turkey respond more quickly or effectively to macroeconomic shocks or sector specific shocks.
