We consider how a principal can optimally outsource information acquisition to an agent in a dynamic environment when the principal can observe neither the agent's effort of collecting information nor signal realizations. Neither initial transaction nor interim payments are allowed to prevent...

This paper considers dynamic moral hazard settings, in which the consequences of the agent's actions is not precisely understood. In a new continuous-time principal-agent model with drift ambiguity, the agent's unobservable action translates to drift set for the diffusion processes that describe...
