Dynamic Multi‐Activity Contests*
研究了一种动态多活动竞赛模型，选手先投入长期活动，再投入短期活动，两种努力互补影响获胜概率。发现顺序竞赛的总努力低于同时竞赛，对军事、诉讼、创新等竞赛组织有启示。
Abstract We develop a model of dynamic multi‐activity contests. Players simultaneously choose efforts in long‐run activities, observe each other's efforts in these activities, and then simultaneously choose efforts in short‐run activities. A player's long‐run and short‐run efforts complement each other in determining the player's probability of winning. We compare the outcomes of this two‐stage model to those of the corresponding model in which players choose efforts in all activities simultaneously. Interestingly, effort expenditures are always lower in the sequential multi‐activity contest than in the simultaneous multi‐activity contest. The implications of this result for the organization of military, litigation, innovation, academic, and sporting contests are highlighted.
