The existence and uniqueness of equilibrium in the international public good model

摘要

The international public good model is an extension of the public good model, allowing for different productivities of producing the public good across countries. By extending the proofs of Bergstrom et al. (1986, 1992), which are the seminal studies in the public good literature, this article develops an international public good model with proofs of the existence and uniqueness of equilibrium.
