The Purity of Impure Public Goods

In this paper we demonstrate how the impure public good model can be converted into a pure with satiation of private consumption, which handled more easily, by using variation aggregative game approach as devised Cornes and Hartley (2007). We point out conditions for utility functions that allow conversion through analysis Nash equilibria conducted in unified way facilitates comparative statics goods. Our also offers new insights on determinants becoming contributor to case well non-neutral effects income transfers when is impure.
