ÇKE HİPOTEZİ YÜKSELEN PİYASA EKONOMİLERİ İÇİN GEÇERLİ Mİ? PANEL VERİ ANALİZİ

Bu çalışmada, 4 yükselen piyasa ekonomisi için ÇKE hipotezi panel veri analizi ile test edilmektedir. Fakat öncelikle, eğim parametrelerinin heterojenliği ve yatay kesit bağımlılığının varlığı test edilmektedir. Daha sonra, heterojenite ve bağımsızlık durumu altında, Im vd. 2003 , Maddala ve Wu 1999 ile Choi 2001 ’e ait panel birim kök testleri, Westerlund 2007 ’un bootstrap ECM eşbütünleşme testi ve Pedroni 2000 ’ye ait FMOLS tahmincisi kullanılmaktadır. Son aşamada ise, panel hata düzeltme modeli PVECM oluşturularak, kısa ve uzun dönem nedenselliğinin yönü tespit edilmektedir. Sonuçlar, sadece uzun dönemde ekonomik büyüme ve enerji tüketiminden, emisyonuna doğru tek yönlü bir nedensellik ilişkisi olduğunu ortaya koymaktadır. Ulaşılan bu sonuç, uzun dönemde söz konusu ülke örneklemi için birtakım politika önerileri de sunmaktadır.

TESTING THE EKC HYPOTHESIS FOR 4 EMERGING COUNTRIES: PANEL DATA ANALYSIS

In this study, it is aimed to test the EKC hypothesis for 4 emerging countries through panel data analysis. However, the presence of slope heterogeneity and cross-sectional dependence is first tested. After that, under the presence of heterogeneity and independence, panel unit root tests of Im et al. 2003 , Maddala and Wu 1999 , and Choi 2001 , bootstrap ECM cointegration test of Westerlund 2007 , and FMOLS estimator of Pedroni 2000 are applied. At the last stage, based on PVECM panel vector error correction model , the direction of short and long-run causalities are defined. The results imply that there is only a unidirectional long-run causality running from economic growth and energy consumption toemissions. This result also provides some policy implications for the long-run
