 A partial public good is one from whose consumption some individuals can be excluded but not others. Mancur Olson gives the example of a parade that is a public good for those living in tall buildings overlooking the parade route but a private good to those who need to buy a ticket for a seat in the stands along the way (Olson 1971: 14). A full public good, by contrast, is one from whose consumption all individuals can be excluded.
