Abstract

Rasyonel beklentiler hipotezine göre, ekonomik birimler mevcut tüm bilgiyi etkin şekilde kullanarak gelecekle ilgili doğru tahminlerde bulunurlar. Hipoteze göre ekonomik birimler hatalı tahminlerde bulunsalar dahi, mevcut bilgiyi kullanarak yapılan hatayı düzeltmeye yönelik beklentilerini şekillendirirler ve bu şekilde sistematik hata yapmazlar.
Bu çalışmada Türkiye için rasyonel beklentiler hipotezinin geçerliliği enflasyon beklentileri özelinde test edilmiştir. Bu kapsamda çalışmada fiyatla ilgili beklentilerin yansızlığı ve etkinliği incelenerek beklentilerin rasyonel olup olmadığı incelenmektedir. Çalışmanın bulgularına göre, enflasyon beklentileri için etkinlik hipotezi kabul edilirken, beklentilerin yansızlığı hipotezi reddedilmektedir. Bu durum, mevcut bilgilerin kullanılıyor olmasına rağmen ekonomik birimlerin doğru tahminler yapamadığını ima etmektedir. Bu nedenle Türkiye için enflasyon beklentilerine ilişkin rasyonel beklentiler hipotezi reddedilmektedir. Ancak sonuçlar, beklentilerin yanlı olmasına rağmen, profesyonel tahmincilerin enflasyonu tahmin ederken birçok değişkeni dikkate aldığını da göstermektedir. Bu ise beklentilerin dikkate alınması durumunda, ekonomi politikalarının uygulanmasında politikaların kısmen etkili olabileceği anlamına gelmektedir.

Testing The Rational Expectations Hypothesis: An Emprical Evidence From Turkey

Abstract

The rational expectations hypothesis suggests that economic agents make accurate forecasts about the future using all available information effectively. According to the hypothesis, even if the economic agents make incorrect estimates, they shape the expectations for correcting the error made using the available information and do not make systematic errors.
In this study, the validity of the rational expectations hypothesis for Turkey, using expectations of the inflation rates, is tested. In this context, it is examined whether the expectations are rational or not by examining the unbiasedness and the efficiency of the expectations about the price. According to results, while the efficiency hypothesis is accepted for the expectations of inflation, the unbiasedness for expectations is rejected in the study. This means that although the current information is being used, economic agents can not make the accurate forecasts. Thus, the rational expectations hypothesis for inlation expectations for Turkey is rejected. However, results also show that although the expectations are biased, professional forecasters take into account many variables while forecasting the inflation. This implies that policies can be partially effective if expectations are taken into account in the implementation of economic policies.
