Santje ludas is research assistant at the Institute for Ecologic Economy Research (IÖW) in Berlin. As a political economist with a focus on sustainability, she is interested in how the transformation of the sharing economy must be framed politically in order to develop in a social and ecological manner. Already during her studies, she dealt with different questions regarding the socio-ecological transformation. In particular, she sees great potential in cooperative and collaborative economies: be it in production, as tested e.g. by the Maker movement in open workshops, in collaborative consumption made possible by sharing platforms or in collaborative forms of organizations such as cooperatives. Hence, he is very curious about the dynamics unfolding in the platform economy around the concept of platform cooperativism and she is interested in which way governance structures can promote socially and ecologically positive dynamics.
