STOCK MARKET REACTIONS TO REGULATORY EVENTS ON EMISSION TRADING: EVIDENCE FROM THE EUROPEAN AIRLINE INDUSTRY

The inclusion of international aviation emissions into the European Union Emission Trading Scheme starting from 2012 is expected to bring additional costs to flights having either origins or destinations at a European Union airport. In turn, this should bring new costs to airlines. The aim of this paper is to analyze how financial markets reacted to the official announcements on this regulatory change. Our findings, using an event- study methodology and employing a sample of 20 European airlines’ stocks, reveal that the stock markets tend not to take these regulatory changes into account in the valuation of the European airlines’ stocks. We also document that the magnitude of the reaction of low-cost airlines is not statistically significant than that of full-service network airlines’ reaction.

HİSSE SENEDİ PİYASALARININ EMİSYON TİCARETİYLE İLGİLİ DÜZENLEMELERE TEPKİSİ: AVRUPA HAVAYOLU ENDÜSTRİSİNDEN BİR KANIT

Uluslararası havacılığın 2012 yılından itibaren Avrupa Birliği (AB) Emisyon Ticareti Sistemine dâhil edilmesinin, başlangıç veya varış noktası bir AB havaalanı olan uçuşlara ilave bir maliyet getirmesi beklenmektedir. Bu da havayollarına yeni maliyetler getirecektir. Bu makalenin amacı, finansal piyasaların bu düzenleyici değişikliğe yönelik duyurulara nasıl tepki verdiğini analiz etmektir. Olay analizi metodolojisi uygulanarak ve 20 adet Avrupalı havayolu şirketine ait hisse senetleri kullanılarak elde edilen sonuçlar, hisse senedi piyasalarının havayolu şirketlerini değerlendirirken bu düzenlemeleri dikkate almama eğiliminde olduklarını göstermektedir. Çalışmanın diğer bir sonucuna göre, düşük maliyetli havayollarına ait hisse senetlerindeki tepkinin derecesi, tam hizmet sunan havayolu hisselerindeki tepkiden farklı değildir
