We show that as populations get large, and with selfish preferences, the level of contributions converges to the one given by voluntary contributions. With altruistic preferences (of the warm glow type), the contributions converge to a level strictly higher than those given by voluntary contributions, even though in general they do not yield first-best levels.engAtribución-NoComercial 3.0 Españatechnical reporthttps://www.ucm.es/icaeopen accessD64H21H41LotteriesPublic goodWarm glowEficiencyFinanzasEconomía pública
