  abstract =	 {Most existing research on peer-to-peer systems
                  focuses on protocol design. In this paper, we
                  consider the issue of free riding in peer-to-peer
                  referral systems. Free riders are agents that refuse
                  either to answer a query or to give referrals. Free
                  riding is detrimental to the system, since it may
                  prevent requesters from finding high quality
                  providers efficiently. To mitigate the issue of free
                  riding, we propose a dynamic pricing mechanism to
                  motivate the agents to behave rationally. Service
                  providers learn appropriate prices of referrals and
                  answers in order to maximize their payoffs through
                  stochastic iterative learning algorithms.},
