Energy imports and manufacturing exports with successive oligopolies and storage
构建了一个包含连续寡头和存储的一般均衡贸易模型，分析能源进口依赖型国家的贸易与产业政策，发现战略性存储可能过度、最优市场集中度非零、进口关税可能为负，且存储补贴和减少长期合同通常能提升福利。
Many industrial countries run a “business model” that is based on oligopolistic export industries which strongly depend on energy imports. This paper uses an analytically tractable general equilibrium model of international trade with successive oligopolies and storage to analyze optimum trade and industrial policies for such countries. There can be over-investment in storage for strategic reasons. Despite double marginalization, there is a non-zero optimum level of market concentration for the domestic industry. The optimum import tariff is most likely negative. Subsidies to storage and reduced use of long term contracts usually raise domestic welfare.
