This paper investigates the relationship between the international oil market and the West Texas Intermediate (WTI)—Western Canadian Select (WCS) price differential. Monthly data were collected for January 2005 to September 2023 from the U.S. Energy Information Administration, the Federal Reserve Bank of Dallas, the Canada Energy Regulator, and the Government of Alberta. The paper finds that a negative oil supply shock increases the differential with a delay. On the other hand, a positive oil-specific demand shock increases the WTI-WCS differential with a delay, while a positive aggregate demand shock increases the differential persistently. Overall, the three shocks in the international oil market account for 61% of the variability in the price differential in the long run. The aggregate demand shock is the most substantial factor in explaining the variation in the WTI-WCS differential in the long run. This indicates that the global oil market demand has an asymmetric effect on WTI and WCS prices.
期刊介绍：
The Atlantic Economic Journal (AEJ) has an international reputation for excellent articles in all interest areas, without regard to fields or methodological preferences. Founded in 1973 by the International Atlantic Economic Society, a need was identified for increased communication among scholars from different countries. For over 30 years, the AEJ has continuously sought articles that traced some of the most critical economic changes and developments to occur on the global level. The journal''s goal is to facilitate and synthesize economic research across nations to encourage cross-fertilization of ideas and scholarly research. Contributors include some of the world''s most respected economists and financial specialists, including Nobel laureates and leading government officials. AEJ welcomes both theoretical and empirical articles, as well as public policy papers. All manuscripts are submitted to a double-blind peer review process. In addition to formal publication of full-length articles, the AEJ provides an opportunity for less formal communication through its Anthology section. A small point may not be worthy of a full-length, formal paper but is important enough to warrant dissemination to other researchers. Research in progress may be of interest to other scholars in the field. A research approach ending in negative results needs to be shared to save others similar pitfalls. The Anthology section has been established to facilitate these forms of communication. Anthologies provide a means by which short manuscripts of less than 500 words can quickly appear in the AEJ. All submissions are formally reviewed by the Board of Editors. Officially cited as: Atl Econ J
