本文证明了完全分散的纯公益经济一般均衡模型中均衡的存在性和一般正则性。以私人产品作为投入的竞争性企业生产公共产品，而公共产品由家庭私人提供。以往关于私人提供公共产品的研究通常使用一种私人产品，一种公共产品模型，其中公共产品是通过规模技术的恒定回报来生产的。作为我们的模型的两个显着特点，我们允许存在几个私人物品和非线性生产技术。在这个框架中，我们使用同伦参数来证明均衡的存在性，我们表明，经济是一般正规的。
Abstract We prove existence and generic regularity of equilibria in a general equilibrium model of a completely decentralized pure public good economy. Competitive firms using private goods as inputs produce the public good, which is privately provided by households. Previous studies on private provision of public goods typically use one private good, one public good models in which the public good is produced through a constant returns to scale technology. As two distinguishing features of our model, we allow for the presence of several private goods and nonlinear production technology. In that framework, we use an homotopy argument to prove existence of equilibria and we show that economies are generically regular.
