题目: Strategic Relations in Acyclic Conflict Networks

摘要：This paper explores the comparative statics results in a model focused on the nexus of bilateral conflicts within a network. By analyzing a network structure characterized by acyclicity, we examine the propagation of shocks originating from a battle or a player to the rest of the network. Our findings uncover a non-monotone yet predictable pattern of shock propagation, which hinges on the relative positions for pairs of contestants in successive battles along the path of shock propagation. Our study reveals the intricate strategic relationships among agents within the network, shedding light on the dynamics of friend-foe identification within a complex conflict structure. In contrast to traditional approaches reliant on closed-form solutions of equilibrium, our method offers a novel illustration of the non-monotone comparative statics results.
