Many types of public goods can be produced privately by profit-seeking entrepreneurs using a modified form of assurance contract, called a dominant assurance contract. The author models the dominant assurance contract as a game and shows that the pure strategy equilibrium has agents contributing to the public good as a dominant strategy. The game is also modeled under incomplete information as a Bayesian-Nash game. Copyright 1998 by Kluwer Academic Publishers
