The overarching objective of this Staff Exchanges (SE) program is to form an international network of organizations from Spain, Germany, Slovenia, and China, working on a joint research program in the fields of health, development economics, and anthropology. Population medicine is a new medical paradigm that aims to improve the aggregate and long-term population health by mobilizing available resources through various care responsibilities. The principles of population medicine are aimed at forcing doctors and physicians to shift from a reactive model that treats ill individuals to a proactive model that focuses on the population's health. This SE Program focuses on how economics, as a collection of theories, models, techniques, and values, might enable practitioners in providing better and more efficient treatment to the population they serve.
