Blomquist and Christensen (2005) argue that welfare is initially decreasing in the price of an excludable public good and that the case for a positive price for an excludable public good price is weak. We argue that this result follows from their particular characterization of the public good and that an alternative and equally reasonable characterization overturns their result. Hence the policy case for a positive price on the public good is stronger than Blomquist and Christiansen suggest. We also provide a flexible characterization of public goods that nests a wide variety of public goods models.
