The effects of parallel trade in two-sided markets
研究了平行进口在双边市场中的影响，发现当产品具有双边市场特性时，平行进口可能提高制造商利润；若双边网络外部性足够大，还能增加各国消费者剩余和社会福利，但若一边外部性小而另一边大，则可能损害消费者和福利。
This study investigates the effects of parallel imports in two-sided markets, which may increase profits for manufacturers when products have a two-sided market nature. Additionally, parallel imports increase consumer surplus and social welfare in all countries if the network externalities from both sides are large enough. However, if one externality is small while the other is large, parallel imports can hurt consumers and welfare in all countries.
