Voluntary Contributions to Multiple Linear Public Goods

There is a lengthy economic tradition studying “public goods. ” Despite the pluralistic title, much of the modeling and experimental work to date has made use of a composite public good. Theorists have recently begun to model economic choice when agents are faced with multiple public goods. Meanwhile there is a lack of behavioural analysis in this area. In this paper, I examine the behavioural effects of the voluntary contributions mechanism when a second, less socially-valued public good exists in a linear payoff environment. There seems to be a small increase in overall public good contributions
