Egalitarian-Equivalent Cost Sharing of a Public Good
提出公共物品的平等等价成本分摊方法，即找到最高公共物品水平使得免费消费该水平能实现可行的效用分配，并证明满足帕累托最优、成本单调性和个体理性或无私家转移的成本分摊方法必然选择平等等价分配。
In an economy with one public and one private good, egalitarian-equivalent cost sharing consists of finding the highest public good level, x*, such that consuming x* for free yields a feasible utility distribution. The corresponding feasible allocation (typically unique), called egalitarian-equivalent, is in the core of the economy. Conversely, any cost sharing method satisfying Pareto optimality, cost monotonicity (nobody suffers a utility loss if the production technology improves upon, ceteris paribus), and individual rationality (no single-agent coalition objects) or no private transfers (no agent receives a positive amount of private good), must select an egalitarian-equivalent allocation in every economy.
