  abstract =	 {We present a domain model and protocol for the
                  exchange of recommendations by selfish agents
                  without the aid of any centralized control. Our
                  model captures a subset of the realities of
                  recommendation exchanges in the Internet. We provide
                  an algorithm that selfish agents can use for
                  deciding whether to exchange recommendations and
                  with whom. We analyze this algorithm and show that,
                  under certain common circumstances, the agents'
                  rational choice is to exchange
                  recommendations. Finally, we have implemented our
                  model and algorithm and tested the performance of
                  various populations. Our results show that both the
                  social welfare and the individual utility of the
                  agents is increased by participating in the exchange
                  of recommendations.},
