One option for developing countries to remedy budget constraints in health care may be to encourage the private sector to assume a greater role in financing and providing health services and to increase collaboration between the public and private sectors. This alternative requires consideration of concepts such as sharing public resources with private providers and determining the division of service financing and provision by sector; many physicians in developing countries allocate their time between jobs in both sectors, and this study examines such multiple job-holding and the impact on both sectors. A review of existing literature reveals that public-private interactions are not well documented. Future research in the area of public-private interactions is recommended for four countries — Egypt, Kenya, India, and Pakistan — because of special attributes in their systems of health care.
