P2P Econ@berkeley
economics-informed design of peer-to-peer, ad-hoc and overlay networks

Project Overview
Fromfile-sharing to mobile ad-hoc networks, community networking toapplication layer overlays, the peer-to-peer networking paradigmpromises to revolutionize the way we design, build and use thecommunications network of tomorrow, transform the structure of thecommunications industry, and challenge our understanding of markets anddemocracies in a digital age.
The fundamental premise ofpeer-to-peer systems is that individual peers voluntarily contributeresources to the system. However, the inherent tension betweenindividual rationality and collective welfare produces a misalignmentof incentives in the grassroots provisioning of p2p services. Ourmulti-disciplinary research team is working to develop a framework forunderstanding the technical and economic characteristics of p2psystems, and to design economic mechanisms for incentive compatible p2papplications.
