摘要: We propose to use supermodularity as a robust dynamic stability criterion for public goods mechanisms with unique Nash equilibrium. Among existing whose equilibria are Pareto efficient, the Groves-Ledyard mechanism is supermodular game if and only punishment parameter sufficiently high, while none of Hurwicz, Walker Kim in quasilinear environment. The Falkinger quadratic environment subsidy coefficient greater than or equal one. These results consistent findings seven experimental studies.
