TÜRKGülüzar KURT GÜMÜŞF. Dilvin TAŞKINEfe Çağlar ÇAĞLI ÖZ Çalışmanın amacı, petrol ve doğal gaz fiyatları ile İMKB imalat sektörü ve kimya-petrol-plastik sektörü endeksleri arasındaki ilişkiyi ortaya koymaktır. 02.01.1997-31.12.2009 döneminin incelendiği çalışmada, geleneksel birim kök testleri ve kırılmalı birim kök testleri ile eşbütünleşme analizleri kullanılmıştır. Kırılmaları dikkate alan test sonuçları, petrol fiyatları ile İMKB imalat sanayi endeksi ve kimya-petrol-plastik sektörü endeksi arasında bir eşbütünleşme olduğunu ortaya koyarken; kırılmaları dikkate almayan testler incelenen endekslerle değişkenler arasında herhangi bir ilişki tespit edememiştir. Çalışmanın sonucu, incelenen veriler üzerinde, kırılmalı birim kök testlerinin, geleneksel birim kök testlerine göre üstün olduğunu göstermesi açısından önem taşımaktadır.

Petrol ve Doğalgaz Fiyatları İle İmalat ve Kimya-Petrol-Plastik Sektörlerinin Endeksleri Arasındaki İlişki

Öz

The aim of this study is to manifest the relationship between oil and natural gas prices, and the indices of ISE manufacturing industry and chemical-petroleum-plastic industry. Unit root and cointegration tests, with and without breaks, are employed in the study where the period between 02.01.1997-31.12.2009 is analyzed. As the results of the tests that are taking the breaks into consideration indicate cointegration between oil prices and indices of ISE manufacturing industry and chemical-petroleum-plastic industry; the tests ignoring breaks do not ascertain any relations between analyzed variables. The results of the study are important in the way that, the unit root tests with structural breaks have superiority over the conventional unit root tests for the used data.
