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