Limited attention has been devoted on how (real-life) social networks are elicited and mapped, even less from the viewpoint of mechanism design. This paper surveys the few mechanisms that have been proposed by the experimental literature to this purpose. These mechanisms di er in their incentive structure, as well as in the means of reward they employ. We compare these elicitation devices on the basis of the estimated di erences in the characteristics of the induced networks, such as the number of (mutual) links, correspondence and accuracy. Our main conclusion is that the elicited network architecture is itself dependent on the nature (and the structure) of the incentives. This, in turn, should provide the social scientist with guidelines on the most appropriate device to use, depending on the research objectives.
