Smith stole a briefcase from Jones, and Jones knows the identity of the thief. The fundamental factor that makes it difficult for the pure rational theorist to predict whether or not Jones will report this theft is:

options:

the problem of not knowing the present expected value of deterrence that would be gained by Jones when he prosecutes

that the briefcase may have been damaged

that Jones could miscalculate the costs and benefits of reporting

that Jones calculated correctly that prosecuting was not worth his while, yet he went ahead anyway because of his anger
