A tractable group all-pay auction
研究群体全支付拍卖中，成员通过群体特定关联设备协调努力，在温和正则条件下存在唯一均衡努力分布，且该分布可通过廉价谈话实现。
We consider group all-pay auctions with a wide range of effort complementarity in which teammates coordinate efforts via a group-specific correlation device. Under mild regularity conditions, there is a unique equilibrium effort distribution, independent of the distribution of the correlation device. We characterize this unique distribution of efforts and analyze the effects of value dispersion, degree of complementarity, and group size. We show that this effort distribution can be achieved without correlation devices as the equilibrium outcome of a cheap talk game in which players engage in costless unmediated preplay communication.
