摘要：Supply shocks in the global gas market may a ect countries di erently, as the market is regionally interlinked but not perfectly integrated. Additionally, high supply-side concentration may expose countries to market power in di erent ways. To evaluate the strategic position of importing countries with regard to gas supplies, we disentangle import price components into increasing and decreasing factors. Due to the complexity of the interrelations in the global gas market, we use an equilibrium model programmed as a mixed complementarity problem (MCP) and simulate the blockage of LNG
ows through the Strait of Hormuz. This enables us to account for the oligopolistic nature and the asymmetry of the gas supply. We nd that Japan faces the most severe price increases, as the Japanese gas demand completely relies on LNG supply. In contrast, European countries such as the UK bene t from good interconnection to the continental pipeline system and domestic pricetaking production, both of which help to mitigate an increase in physical costs of supply as well as in the exercise of market power.
