AI总结:

本文研究社交网络中的拍卖问题,针对单件设置刻画了网络拍卖在弱预算平衡、个体合理性、激励兼容性及效率等方面的性质,并利用奖励等新概念设计了有效且尽可能满足激励兼容性的机制,为理解社交网络拍卖提供了见解。

摘要:

随着网络的发展,通过社交网络推广产品已成为一个重要问题。对于社交网络中的拍卖,需要将物品出售给网络中的智能体,其中每个智能体可以出价,也可以将销售信息扩散给她的邻居。因此,智能体的社会关系与她们在拍卖中的出价相互交织。在网络拍卖中,经典的 VCG 机制无法保留关键性质。为了更好地理解网络拍卖,在本文中,我们针对单件设置,从弱预算平衡、个体合理性、激励兼容性、效率及其他性质方面刻画了网络拍卖。例如,我们提出了机制有效且(弱)激励兼容的充分条件。借助这些性质以及奖励、参与奖励等新概念,我们展示了如何设计有效的机制以尽可能满足激励兼容性,以及设计激励兼容机制以最大化收益。我们的结果为理解社交网络中的拍卖提供了见解。

英文摘要:

With the growth of networks, promoting products through social networks has become an important problem. For auctions in social networks, items are needed to be sold to agents in a network, where each agent can bid and also diffuse the sale information to her neighbors. Thus, the agents' social relations are intervened with their bids in the auctions. In network auctions, the classical VCG mechanism fails to retain key properties. In order to better understand network auctions, in this paper, we characterize network auctions for the single-unit setting with respect to weak budget balance, individual rationality, incentive compatibility, efficiency, and other properties. For example, we present sufficient conditions for mechanisms to be efficient and (weakly) incentive compatible. With the help of these properties and new concepts such as rewards, participation rewards, and so on, we show how to design efficient mechanisms to satisfy incentive compatibility as much as possible, and incentive compatibility mechanisms to maximize the revenue. Our results provide insights into understanding auctions in social networks.
