This research studies the impact of minimum contribution requirements on public goods provision in infinitely repeated games. While in static setups such requirements enhance welfare by surpassing non-cooperative Nash equilibria, their effectiveness in dynamic settings where cooperation relies on Nash reversion strategies remains an open question. This study reveals that the introduction of a minimum contribution requirement, positioned between the Nash equilibrium and the agreed cooperative level, hinders long term cooperation among symmetric players, under a quasi-linear and the constant elasticity of substitution (CES) utilities.
