Private provision of public goods under price uncertainty: a comment

We revise a result positing that there is a positive relationship between contributions and welfare in a public good provision game under price uncertainty (Gradstein et al. Soc Choice Welf 10(4):371–382, 1993). The authors state in Proposition 3 that welfare decreases when price uncertainty induces a reduction in private contributions. By contrast, we show that, under certain conditions, a reduction in contributions can be associated with an improvement in consumer welfare. This result is important because public policy regarding the provision of public goods is often based on indicators such as citizen participation, which, as this note shows, may constitute a misleading signal.
