Evaluating policy change in physician manpower planning

The decade of the 1980s witnessed a revitalization of free-market interest in the use of incentives and voluntary participation to promote activities in a wide range of fields. Because of its history of decentralized control over physician residency training, the state of New Jersey found such an approach appealing when it sought to restructure its graduate medical education system. Two statewide task forces spent a year developing policy changes designed to produce voluntary changes in such areas as the size and growth of the state system. However, a 2-year follow-up survey of the directors of state residency programs revealed little perceivable change.
