Two experiments on trading information goods in a network
通过实验研究网络中的循环路径对可复制信息商品交易的影响，发现循环路径下首次交易价格反而更高，与理论预测相反。
We examine the impact of a cycle path on the trading of a copyable information good in a network experimentally. A cycle path in a network allows a buyer to become a reseller who can compete against existing sellers by replicating the good. A theoretical prediction considers that the price of the information good, even with the first transaction where there is not yet a reseller competing with the original seller, will be lower in networks with a cycle path than otherwise. However, our experiment reveals that the observed price for the first transaction is significantly higher in networks with a cycle path. An additional experiment that enhances competition also does not support the theoretical prediction.
