This paper analyzes the optimal content regulation of direct-to-consumer advertisement (DTCA) in a pharmaceutical market, with particular focus on the distinction between product and enlightenment advertisement. Firms are allowed to freely promote their own specific products under product DTCA,...

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...

We consider a bandit problem faced by a team of two heterogeneous players. The team is hierarchical in that one (the principal) retains the exclusive right to terminate the project while the other (the agent) focuses strictly on implementing the project assigned to him. As a key departure, we...

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...

In most firms, if not all, workers are divided asymmetrically in terms of authority and responsibility. In this paper, we view the asymmetric allocations of authority and responsibility as essential features of hierarchy and examine why hierarchies often prevail in organizations from that...

We consider a “tenure-clock problem” in which a principal may set a deadline by which she needs to evaluate an agent's ability and decides whether to promote him or not. We embed this problem in a continuous-time model with both hidden action and hidden information, where the principal must...

We consider an environment in which a principal hires an agent and evaluates his productivity over time in an ongoing relationship. The problem is embedded in a continuous-time model with both hidden action and hidden information, where the principal must induce the agent to exert effort to...

A standard incomplete-information war of attrition is extended to incorporate experimentation and private learning. We obtain a characterization of all equilibria in this extended setup and use this setup to illuminate a tradeoff between short-run and long-run gains of experimentation. The...
