This paper assesses the extent to which provider payment mechanisms can help developing countries address their leading health care problems. It first identifies four key problems in the health care systems in developing countries: 1) public facilities, which provide the bulk of secondary and tertiary health care services in most countries, offer services of poor quality
2) providers cannot be enticed to rural and urban marginal areas, leaving large segments of the population without adequate access to health care
3) the composition of health services offered and consumed is sub-optimal
and 4) coordination in the delivery of care, including referrals, second opinions, and teamwork, is inadequate. The paper examines each problem in turn and assesses the extent to which changes in provider payments might address it.
