Conversations among Competitors
构建了一个双边对话模型，其中参与者诚实地与竞争对手交换想法。激励相容的关键在于信息结构的互补性：只有获取对方先前的想法，才能产生新见解。研究还发现，在社交网络中，相对不成熟的想法可以远距离传播，而更有价值的想法则倾向于局限在小群体内。
I develop a model of bilateral conversations in which players honestly exchange ideas with their competitors. The key to incentive compatibility is complementarity in the information structure: a player can generate a new insight only if he has access to his counterpart's previous thoughts on a topic. I then examine a social network in which A has a conversation with B, then B has a conversation with C, and so on. Relatively underdeveloped ideas can travel long distances over the network. More valuable ideas, by contrast, tend to remain localized among small groups of agents.
