This paper aims to investigate stochastic properties of the consumption-income ratios in 11 Central and Eastern European (CEE) countries. We use the heterogeneous panel unit root tests those account for cross-sectional dependence and the Modified Augmented Dickey-Fuller unit root test over the period March 1997-September 2012 in quarterly data set. We find the strong mean-reversion in the consu...

We combined recent developments in univariate and multivariate unit root testing in order to construct a more-powerful panel unit root test. We extended the GLS-detrending procedure of Elliott, Rothenberg, and Stock (1996) to a panel Augmented Dickey-Fuller test. The finite sample power properties of the new test demonstrate a very large gain when compared to existing tests, especially for smal...

Bu çalışmada M. Friedman’ın vergi-harcama hipotezi Türkiye (2006-2022) örneği üzerinden araştırılmıştır. Araştırmanın uygulaması iki aşamada gerçekleştirilmiştir. İlk olarak araştırmanın değişkenleri geleneksel birim kök testlerine (Augmented Dickey-Fuller ve Phillips-Perron testlerine) tabi tutulmuş ardından Engel-Granger koentegrasyon analizi yapılmıştır. İkinci değişkenler yapısal kırılmalı ...

This study aims to evaluate the link between economic growth and consumer price index (CPI) in Japan for the period of 1980-2014. Initial series were adjusted for stationarity using the Augmented Dickey- Fuller (ADF) test for unit root followed by the application of Johansen Co-integration Test in order to examine the long-run relationship among the variables, while the causalities were evaluat...

The contribution of this paper is twofold. First we extend the large sample results provided for the augmented Dickey-Fuller test by Said and Dickey (1984) and Chang and Park (2002) to the case of the augmented seasonal unit root tests of Hylleberg et al. (1990) [HEGY], inter alia. Our analysis is performed under the same conditions on the innovations as in Chang and Park (2002), thereby allowi...

VIX Endeksi, piyasalardaki tedirginliği ve korku halini yansıttığı için piyasalarda oluşabilecek olan krizlerin öncü göstergesi olarak da bilinmektedir. Bu çalışmanın amacı Endeksi’nin Türkiye’de yapılan kamu harcamaları gelirleri üzerindeki etkisini incelemektir. bağlamda çalışmada, 1999-2021 dönemine ait Endeksi verileri analiz edilmiştir. Serilerin birim kök içerip içermediği Augmented Dicke...

Econometricians typically make use of functional central limit theorems to prove results for I(1) processes. For example, to establish the limit distributions of unit root tests such as the Phillips–Perron and Dickey–Fuller tests, the functional central limit theorem plays a crucial role. In this paper, it is pointed out that for linear processes, minimal conditions that ensure that only a cent...
