Internet has profoundly revolutionized the economy. The disruptive nature of this revolution is both fascinating and a source of concerns. On one hand, the platforms allow for optimization of resources previously underutilized (blablacar, leboncoin etc.)… but at the same time, entire sectors of the economy can be “uberized” overnight! In this session, we will hear from active entrepreneurs at the forefront of this “collaborative economy” based on pooling resources and creativity. We will discuss this phenomenon from the stance of responsible economy with French and International actors. Beyond any ideological prejudice, we will analyse the economic, environmental and societal implications of replacing traditional business models (in various sectors as illustrated by the speakers) by these new designs.
