摘要:Deriving a tractable equilibrium in group all-pay contests with an additive impact function under both intra- and inter-group incomplete information presents a signiffcant analytical challenge. We address this by employing foundational assumptions à la global games, which enables the derivation of an analytical equilibrium. We then extend the model by incorporating local and global public information about contest fundamentals and derive an approximate solution, whose broad applicability is corroborated through numerical simulations. Our analysis reveals that public information can serve as a powerful coordination device, aligning agents’ strategic choices not only within but also between groups. This coordination reduces rent dissipation and ensures that the coordination effect of public information always dominates its misallocation effect, thereby enhancing social welfare in group contests for a club-good prize.
在具有加性影响函数的群体全付竞赛中,考虑群内和群间不完全信息条件下,推导出一个可行的均衡具有重要的分析挑战。我们通过采用类似于全局博弈的基础假设来应对这一挑战,从而得出一个解析均衡。随后,我们在模型中引入关于竞赛基本面的一般和局部公共信息,并推导出一个近似解,其广泛的适用性通过数值模拟得到了验证。我们的分析表明,公共信息可以作为一种强有力的协调工具,不仅在群内,还在群间协调代理人的战略选择。这种协调作用减少了租金的流失,并确保公共信息的协调效应始终优于其错配效应,从而提升了为俱乐部型奖品进行的群体竞赛中的社会福利。
