In many facets of life, we often face competition with a multilayered structure in which different levels of competition take place simultaneously. In this paper, we propose a new class of tournament models, called multilayered tournaments, to capture this type of competitive environment. Among...

This paper explores the consequences of sabotage for the design of incentive contracts. The possibility of sabotage gives rise to a dynamic concern, similar to the Ratchet effect, which distorts the agents' incentives. We first show that the mere possibility of sabotage may make it impossible to...

This paper explores the consequences and implications of the "dual role of promotion" in an environment where a firm must simultaneously achieve two distinct goals - assignment and incentive provision - via the strategic use of promotions. We argue that the efficient promotion rule is generally...

In this paper, we consider a dynamic signaling model of an R&D market in which a researcher can choose either a safe project (exploitation) or a risky project (exploration) at each instance. We argue that there are substantial efficiency gains from rewarding minor innovations above their social...

This paper examines the optimal provision of incentives in the repeated setting with many agents under the restriction that only relative performance evaluation is feasible for contracting. We show that the optimal contract in the repeated setting may take a different form than that in the...

This paper examines a two-period tournament where agents may possibly engage in destructive sabotage activities. Under plausible circumstances, sabotage proves to be an effective tool for low-ability agents, especially when they are faced with high-ability opponents. The possibility of sabotage...
