 Distinctions can also be drawn among public goods. Most public goods do not affect all inhabitants of a large community equally. Fire protection services in Lower Manhattan are not consumed by those living in the Bronx, much less by Californians. Public parks benefit those who live in the neighbourhood, playgrounds only those who live in the neighbourhood and have children of a certain age (and indeed they might constitute a public bad for others). Charles Tiebout has developed a theory of local government, after which the term “local public good” was coined (Tiebout 1956, Stiglitz 1982). Other public goods may benefit all of humanity, such as climate change mitigation. We can therefore distinguish local, national, and global public goods (on the latter, see Kaul et al. 2003).
