PUBLIC-EXPENDITURE UNDER UNCERTAINTY - THE NET-BENEFIT CRITERIA
建立了一个模型，在不确定性下决定公共品和私人品的提供数量，并基于净收益函数给出帕累托改进或帕累托最优的必要充分条件。
Public expenditure under uncertainty is modeled as the problem of determining the quantities of l public goods and m private goods to be provided to n consumers when the private goods are claims to a single commodity, "dollars, " which are contingent upon the occurrence of one of m possible states of nature. A real-valued "net benefit function" is identified, and criteria based upon this function are provided that are both necessary and sufficient for Pareto-improving or Pareto-efficient solutions to this problem.
