摘要

我们建立了一个存在全球共同所有权的国际寡头垄断模型。我们从理论上研究了共同所有权如何影响寡头垄断市场的国际贸易量和全球福利。我们发现，当国际运输成本低（高）时，福利会随着共同所有权程度的增加而减少（增加），而共同所有权会减少国际贸易。这一结论在进口关税和共同所有权份额不对称的情况下依然有效。

Welfare effects of common ownership in an international duopoly

We formulate an international oligopoly model in the presence of global common ownership. We theoretically investigate how common ownership affects the volume of international trade in an oligopoly market and global welfare. We find that welfare decreases (increases) with the degree of common ownership when the international transport costs are low (high), whereas common ownership reduces international trade. This conclusion remains valid in the presence of import tariffs and asymmetric common ownership share.
