Medical malpractice liability and physician migration
This paper uses national data on individual physicians and two control groups to provide evidence on the extent to which each of five medical malpractice reforms impacts the decision to move one's medical practice to another state. We find robust evidence that states that have implemented noneconomic damage caps experience less out-migration of physicians than states that do not have these reforms. In addition, we find some evidence that joint and several liability reforms and patient compensation funds also impact the migration decisions of physicians.
