Abstract

The main aim of this study is to improve the SURADF panel unit root test of Breur et al. (2001) by considering structural breaks and the knowledge of non-normal distrubited residuals. Chang et al. (2012) introduce a new panel unit root test by allowing smooth structural breaks in SURADF test process, in this study, we also take into account of the information of the residuals that are nonnormally distrubited. We test the validity of stochastic convergence among 18 OECD countries using this suggested new test and find a supportive evidence of convergence for only 7 countries.

OECD Ülkelerinde Yakınsama Hipotezinin Geçerliliği: Kalıntılarla Genişletilmiş Panel Fourier SURADF Birim Kök Testi

Abstract

Bu çalışmanın amacı Breuer vd. (2001) tarafından önerilen SURADF birim kök testini yapısal değişim ve kalıntıların normal dağılmama bilgisini dikkate alan yapıya genişleterek OECD ülkeleri için gelir yakınsamasının geçerliliğini test etmektir. Breuer vd. (2001) tarafından geliştirilen panel SURADF birim kök testi, Chang vd. (2012) tarafından yumuşak kırılmalara izin verecek şekilde genişletilmiştir; bu çalışmada ise bu denklem sistemine Im ve Schmidt (2008) tarafından önerilen kalıntıların normal dağılmama bilgisinin de dâhil edildiği yeni bir test önerilmiştir. Önerilen bu yeni birim kök testi kullanılarak, seçilen OECD ülkeleri için yakınsama hipotezinin geçerliliği sınanmış ve ele alınan 18 ülkenin sadece yedisinde stokastik yakınsamanın geçerli olduğu sonucuna varılmıştır.
