现行国际货币体系下的货币竞争——基于双元寡头垄断模型的分析

Currency Competition under the Current International Monetary System——An Analysis based on the Duopoly Model

当前的国际货币体系下,国际货币的竞争可近似看成是美元和欧元的双元寡头垄断格局。在此假设下,通过差异性双元寡头的Cournot模型和差异性Hotelling模型的分析可以得出,欧元要增加市场份额并增强对美元的制衡能力,需要提高其在币值的稳定性、兑换的便利性及人们的信心等方面与美元的差异性。

Currency competition under the current international monetary system can be seen as the Duopoly structure consisting of US dollar and the Euro.Under this assumption,we use the Cournot model and Hotelling model to conclude that in order to increase market share and better rival US dollar,the Euro need to improve the stability of its value,strengthen the convience of currency exchange,and enhance people's confidence.
