A Note on Distributive Equity and Social Efficiency
提出一个包含常见社会福利函数（如边沁式或罗尔斯式）作为特例的新函数，通过一个简单参数实现社会效率与分配公平之间的权衡。
This note proposes a social welfare function (SWF) where most functions, such as the Benthamite or the Rawlsian functions, found in the literature can be considered particular cases. Moreover, the SWF propounded let us obtain compromises or balances between the welfare criteria of social efficiency and distributive equity. The level of compromise or balance is established with the help of a simple and operational parameter.
