Problems of public goods optimum size determination

The problem of public goods optimum size determination is examined in the article. The author examines several models and approaches for optimum size determination. Production of public goods is an actual problem that government faces. How, in what quantity and for what price should goods that can be used by everybody be produced? And what’s more, who must be responsible for its maintenance? A lot of economists for a long time are trying to answer these questions, but after the analyses made by the author, it’s getting clear that none of the models can be called sufficiently full and precise.
