Dr. Winnie Yip’s research focuses on: 1) the design, implementation and evaluation of systemic health care interventions, for improving affordable and equitable access to and the efficiency and quality of health care delivery, especially for the poor; and 2) modeling and evaluating the effects of incentives on the behavior of providers (organization and individual) and patients.
Dr. Yip’s research encompasses both why health systems fail and how to improve them for the benefit of the people they serve. Her approach typically involves large-scale social experimentation of health system interventions by using experimental design to integrate the transformation of financing, incentives, organization and management. With a network of Chinese universities, Dr. Yip’s ongoing research projects cover over 25 million people in the low income provinces.
Dr. Yip often works in close collaboration with governments and she has extensive experience leading interdisciplinary teams with expertise in public health, economics, political economy, evaluation science, epidemiology, quality of care, marketing science, and management.
