How Diagnostic Tests Affect Prevention: a Cost-Benefit Analysis

Author

Listed:

Abstract

The purpose of this paper is to offers insight for evaluating research and development in diagnostic tests. We show that a rational policy maker perfectly informed about health risks may choose to reduce investment in prevention when efficient diagnostic tests become available. We show that prevention and diagnostic tests are substitutes rather than complements. As a result the regular improvements in diagnostic technology that are observed can justify a lower investment on prevention at any given unitary price for this activity. The analysis is a useful tool for the allocation of funding between diagnostic and preventive medicine.
