Clarke mechanism
WebGroves-Clarke mechanisms, with the property that truth-telling is a domi-nant strategy [Vickrey (1961), Groves (1970), Clarke (1971)]. But a Vickrey-Groves-Clarke mechanism will in general fail to balance the budget (the mon-etary transfers employed to induce truthful revelation do not sum to zero), WebClarke's three laws, written by the British science fiction writer and futurist Arthur C. Clarke, are his observations on the nature of technology and discovery.
