Abstract
The studies of judgment proof problem are based on analyses using the models in which firms' activities are fixed, although the activities are variable for them and, in the court, their negligence is not always judged by the formalized care in the previous studies. Furthermore the studies have not used numerical method, because likely probability and damage function can not be decided as the definition of care is inappropriate. This paper denotes result of analysis by numerical method using the model in which firms' care is decoupled with the formalized one and firms' activities are variables. It shows that, even under negligence rule, judgment proof problem is more serious than in the previous studies.
