The market for reputations as an incentive mechanism

Reputational career concerns provide incentives for short-lived agents to work hard, but it is well known that these incentives disappear as an agent reaches retirement. This paper investigates the effects of a market for firm reputations on the life cycle incentives of firm owners to exert effort. A dynamic general equilibrium model with moral hazard and adverse selection generates two main results. First, incentives of young and old agents are quantitatively equal, implying that incentives are "ageless" with a market for reputations. Second, good reputations cannot act as effective sorting devices: in equilibrium, more able agents cannot outbid lesser ones in the market for good reputations. In addition, welfare analysis shows that social surplus can fall if clients observe trade in firm reputations.
