(with Alessandro Ispano)
We provide an equilibrium model of interrogations with two-sided asymmetric information. The suspect knows his status as guilty or innocent and the likely strength of the law enforcer's evidence, which is informative about the suspect's status and may also disprove lies. We study the evidence strength standards for interrogating and drawing adverse inferences from silence that minimize prosecution errors. We consider the law enforcer's incentives to confront the suspect with the evidence, both at once and gradually. We describe the optimal mechanism under full commitment and a back and forth interrogation with discretionary punishment of lies that implements the optimum in equilibrium with hard evidence. We also consider scenarios where interrogations can be delegated. We describe a dynamic interrogation with two-sided information revelation without hard evidence but with delegation implementing the optimum in equilibrium.
