Estimating the price premium of LNG in Korea and Japan: The price formula approach

다국어 초록 (Multilingual Abstract)

<P><B>Abstract</B></P> <P>Focusing on the price premium, which reflects the negotiation power of exporting and importing countries, this study empirically investigates the liquefied natural gas (LNG) price formula for Korea and Japan. Applying the state-space model and Kalman filter to the price formula adopted in the LNG contracts in the Asia–Pacific region, this study estimates the long-run price formula and time-varying premiums on the LNG import prices by trade routes, from Qatar, Oman, Indonesia, and Malaysia, to Korea and Japan. Furthermore, this study also discusses the differences between Korea and Japan and the event-based changes in the price premiums, namely, the appearance of Russia as a new supplier to Korea and Japan in April 2009, and the Fukushima nuclear disaster in March 2011. The estimation results show that the appearance of a new supplier does not always lead to a decrease in the premium. In addition, LNG importers in Northeast Asia should pay attention to demand and supply in Europe as well as Asia because Northeast Asia and Europe share the same Middle Eastern exporting countries. Furthermore, Korea, Japan, and other Northeast countries need to establish close cooperation to enhance their negotiation power within the global LNG market.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The price formula and time-varying premium of LNG for Korea and Japan were estimated. </LI> <LI> The appearance of new LNG supplier does not always mean the decrease in premium. </LI> <LI> After Fukushima nuclear disaster, the premium on LNG from Indonesia and Malaysia increased. </LI> <LI> The overall increases in the premium of Japan were higher than that of Korea. </LI> </UL> </P>
