摘要翻译：
我提出证据表明，市场参与者之间的沟通是对市场需求的重要影响。我发现消费者需求受到正式和非正式网络沟通的影响大致相同，即产品评论和社区论坛。此外，我发现经验证据表明，供应商承诺披露的能力抑制了沟通对需求的影响。我还发现，随着消息数量的增加，产品需求对平均客户情绪的反应更快，这在贝叶斯更新框架中是可以预期的。

英文摘要：
  I present evidence that communication between marketplace participants is an important influence on market demand. I find that consumer demand is approximately equally influenced by communication on both formal and informal networks- namely, product reviews and community forums. In addition, I find empirical evidence of a vendor's ability to commit to disclosure dampening the effect of communication on demand. I also find that product demand is more responsive to average customer sentiment as the number of messages grows, as may be expected in a Bayesian updating framework.
