We consider the problem of implementing a fixed social choice function between multiple players (which takes as input a typetifrom each playeriand outputs an outcomef(t1,…,tn)), in which each player must be incentivized to follow the protocol. In particular, we study the communication requirements of a protocol which: (a) implementsf, (b) implementsfand computes payments that make it ex-post incentive compatible (EPIC) to follow the protocol, and (c) implementsfand computes payments in a way that makes it dominant-strategy incentive compatible (DSIC) to follow the protocol.We show exponential separations between all three of these quantities, already for just two players. That is, we first construct anfsuch thatfcan be implemented in communicationc, but any EPIC implementation off(with any choice of payments) requires communication exp(c). This answers an open question of [Fadel and Segal, 2009; Babaioff et. al., 2013]. Second, we construct anfsuch that an EPIC protocol implementsfwith communicationC, but all DSIC implementations offrequire communication exp(C).
