Welcome to the website of FADeRiS, a series of workshops on the Foundations and Applications of Decentralized Risk-Sharing. 

Risk-sharing mechanisms have been studied for decades in the actuarial literature, starting with the pioneering work of Karl Borch who investigated equilibrium in a reinsurance market in the early 1960s. Decentralized risk-sharing refers to risk-sharing mechanisms under which the participants in a pool decide to share their risks among themselves.  As mentioned above, investigating  how to determine 'fair' contributions in a decentralized risk-sharing problem is an old research problem in the actuarial and risk-sharing literature. The recent interest in a sharing economy, collaborative consumption, and decentralized finance, together with recent advances in technology, have led to a renewed academic interest in decentralized risk-sharing mechanisms. Moreover, in practice, peer-to-peer (P2P) or collaborative insurance revives early forms of mutual insurance, where the contributions of the many are used to cover the misfortunes of the few, while keeping insurer’s experience in claim settlement and risk-bearing capital. 

Taking into account these new practical and theoretical evolutions, we have decided to create and maintain an academic forum for research on decentralized risk sharing and its applications.

The first FADeRiS workshop was organized in May 2023 at KU Leuven. We are looking forward to facilitating future editions of our FADeRiS workshop at other locations.
