Revisiting Jansen et al.'s Modified Cournot Model of the European Union Natural Gas Market
In this paper we reconsider Jansen et al.'s (2012) Cournot model of the European Union natural gas market with three major suppliers Russian Gazprom, Norwegian Statoil, and Algerian Sonatrach. To reflect Russiaâ€™s geopolitical consideration, we incorporate a relative market share to Gazpromâ€™s objective function. Compared with Jansen et al.â€™s use of standard market share, our study shows that the introduction of relative market share makes it not only possible to derive the same results in a more general environment, but also permits us to obtain clear-cut quantitative analysis results for equilibrium solution, consumer surplus, and social welfare. Our analysis also demonstrates for this modiï¬ ed Cournot model that by seeking a proper market share, Gazprom can achieve the same profits of a Stackelberg leader in a simultaneous move model as in the classical sequential move leader-follower model. When Gazprom pursues the control of market share besides proï¬ ts, it will be good news for the EUâ€™s consumers but bad news for its rivals.
