There is a fundamental question asked in public health and health care in general: how can we get the best results, in terms of better health, from the resources which are available in the community? Health Economics, as a field, attempts to provide an explicit and rationale framework to improve the efficient and equitable allocation of health care resources. In this course, we will examine selected topics in health economics that have major implications for healthcare delivery, and clinical and public health research. Essential economic theories and methods for exploring each topic will be discussed, along with the role of markets and government. In addition, basic skills of conducting economic evaluation, such as cost-effectiveness analysis, will also be introduced.
