双寡头市场价格博弈分析——以我国国内成品油市场竞争主体为例

用博弈论分析市场行为是经济学的发展方向之一,本文从实证分析国内成品油市场中国石化与中国石油两大寡头的多种博弈情形及其收益变化过程,论证了在市场需求总量基本恒定状态下,双寡头市场价格博弈的纳什均衡解为(降价、降价),(不降价、不降价),前一种均衡解是双方在势均力敌、信息反馈充分的恶性竞争结果,后一种是在满足一定收益前提下的“双赢”策略。企业只有选择有别于竞争对手的非价格歧异性策略,形成自己的特色和优势,才能占领相应的市场,获得相应的经济效益。     

环境保护的国际合作：以SARS为例

SARS危机反映了当前环境问题日渐国际化的趋势,其根源是资源紧缺和经济全球化之间的矛盾。面对这一问题,各国应通力合作、寻求对策,实现环境保护的国际合作。但环境责任在各国间的分配问题阻碍了国际环境合作的进展。本文指出,基于环境和国力的全球合作机制可合理分配各国的代际责任和代内责任,有利于促进环境保护的国际合作,是一种可行的环境保护国际合作模式。要实现这一目标,首先要各国在代际和代内责任的问题上达成共识,二是要增加国际机构、国际公约对合作各方的约束力。

Estimating Krugman’s Economic Geography Model for the Spanish Regions

This paper estimates Krugman’s (J Polit Econ 99:413–499, 1991) economic geography model using data from the Spanish NUTS 3 regions. The econometric formalization endogenously determines wages in a region as a function of income and wages in other regions. The specification adopted also allows us to study the relation between the agglomeration of economic activity, increasing returns and market access. The first result obtained is that the Spanish economy exhibits a spatial wage structure: wages in a region are positively determined by income and wages in neighboring regions. In second place it is found support for the structural relations of the underlying theoretical model, indicating the importance of scale economies and transport costs in shaping the Spanish economic geography.     

Learning by doing,spillovers and shakeouts

This paper studies industry evolution driven by non strategic learning by doing and spillovers. We characterize a dynamic process of cost and output changes and its effect on welfare and industry profits. The paper gives conditions for shakeouts to occur and analyzes the key factors affecting these conditions. Since shakeouts could lead to a long-run social loss due to higher market concentration, there is a role for a government to play in limiting unnecessary shakeouts. The most effective way to do so is to enhance spillovers.JEL Classification: L11, L13, O31Correspondence to: Michael TroegeWe would like to thank Hans Mewis, Christophe Moussu and an anonymous referee for valuable comments and suggestions.
