摘要:
Long-term take-or-pay contracts regulating gas exports to the Continent are described and analyzed. We thereafter examine whether the German gas market is integrated. Time series of Norwegian, Dutch and Russian gas export prices to Germany in 1990-1998 are examined. Cointegration tests show that that the different border prices for gas to Germany move proportionally over time, indicating an integrated gas market. We find differences in mean prices, with Russian gas being sold at prices systematically lower than Dutch and Norwegian gas. Among the explanatory factors for price discrepancies are differences in volume flexibility (swing) and perceived political risk. (C) 2002 Elsevier Science B.V. All rights reserved.
