Empirical strategy-proofness (1907.12408v5)
Published 29 Jul 2019 in econ.TH and cs.GT
Abstract: We study the plausibility of sub-optimal Nash equilibria of the direct revelation mechanism associated with a strategy-proof social choice function. By using the recently introduced empirical equilibrium analysis (Velez and Brown, 2019, arXiv:1804.07986) we determine that this behavior is plausible only when the social choice function violates a non-bossiness condition and information is not interior. Analysis of the accumulated experimental and empirical evidence on these games supports our findings.
