Gold is an important investment tool especially in developing countries. Return-on-gold and prediction thereof is a topic which has been attracting the attention of investors and densely studied recently. For this reason different methods are being used to predict return-on-gold and effectiveness of these methods are being compared. The purpose of this study is to generate a prediction of return-on-gold using artificial neural networks and GARCH and its derivatives, which is a conventional time series method, based on the series obtained from the return of gold values provided by Turkish Gold Exchange belonging to the February 2014 and June 2014 period. As a result of this study, contrary to the expectations and the majority of similar studies, ANN provided less successful outcomes compared to GJR GARCH method.

We examine the stationarity properties of primary energy consumption for "Fragile Five" countries and assesses whether shocks on coal, natural gas, and oil consumption are permanent or temporary. The findings suggest that shocks on coal consumption are temporary for Brazil, South Africa, and Turkey, while are permanent for India and Indonesia. Moreover, the effect of shocks on natural gas consumption is temporary for five fragile countries except for South Africa. Finally, it is found that shocks on oil consumption are temporary for only India and Indonesia.

This paper investigates the validity of the Fisher Hypothesis in Turkey coveringthe period 2003 – 2012. To test validity of Fisher Hypothesis, this paper uses anAutoregressive Distributed Lag test for threshold cointegration recently introduced in theliterature by Li and Lee (2010). The empirical results which are obtained from this paperindicate that Fisher hypothesis is valid for Turkey, meaning nominal interest rates wouldbe an important leading indicator for inflation.

ÖzTürkiye'de yastık altı altın kimi hesaplamalara göre 3-5 ton arasında olup değeri de 200-300 milyar doları bulmaktadır. 2020 yılı başlarında ortaya çıkan ve tüm dünyayı etkisi altına alan COVID-19 pandemi süreci ülke ekonomilerini çok zora sokmuştur. Tüm dünyada olduğu gibi Türkiye'de de ekonomi yavaşlamış ve daralmıştır. Yastık altı altın yavaşlayan ekonomiye bir nebze de olsa canlılık kazandırır. Bu çalışmanın amacı Türkiye'de yastık altı altının ekonomiye kazandırma yollarını araştırmaktır. Bu doğrultuda altın bankacılığını da içeren anket uygulanmıştır. Anakütle olarak İstanbul ili seçilmiş olup yüz yüze görüşme yapılmıştır. Tesadüfi örnekleme yöntemi ile elde edilen örneklemde toplam 1002 kişi ankete katılım sağlamıştır. Soruların içeriğinde yaş, cinsiyet, medeni durum, öğrenim durumu gibi temel sorular yatmaktadır. Açık uçlu olarak da aylık ortalama gelir ve aylık ortalama tasarruf soruları sorulmuştur. Altın bankacılığı içeren soru tipleri ise; 8 adet evet-hayır ve 26 adet 5'li Likert ölçeği sorularından oluşmaktadır. Sorular neticesinde elde edilen verilere Faktör Analizi uygulanmıştır. Söz konusu uygulama sonrasında elde edilen faktörler kullanılarak Gompit Regresyon Modeli tahmin edilmiş olup, analiz ile birlikte altın bankacılığı sistemini bilgi sahibi olunmadığı ve bankalara olan güven duygusunun eksikliği sonuçları ortaya çıkmıştır.

However, the complex interactions between economic variables and the range of economic instruments complicate to obtain these goals. In addition, the economical and behavioural habits of the society and the market economy structure of the nation force the state to choose among the policies.
