P4P / Pay for Performance

The project P4P applies experimental economic methods to study the behavior of actors in health care, particularly of independent physicians. Understanding and even predicting their behavior allows for well-founded policy recommendations on how best to increase competition in the health care system. By conducting laboratory experiments not only with student subjects but also with physicians themselves, a thorough understanding of physician preferences can be achieved.
