On the occasion of the annual conference of the German Society for Health Economics e.V. (DGGÖ), the paper "Inattention and Switching Costs as Sources of Inertia in Medicare Part D" by Prof. Dr. Florian Heiss (together with Daniel McFadden, Joachim Winter, Amelie Wuppermann, Bo Zhou) was awarded the "DGGÖ Science Prize for the best health economics publication of the year". The paper explores the question of why consumers rarely change health insurers, even though better offers would be available to them.

The DGGÖ aims to promote science, research and scientific policy advice in the field of health economics. Its tasks also include the organization of scientific events and research projects as well as the awarding of prizes and distinctions. In particular, an annual scientific conference is held every spring.
