Lifeline Electricity Rates as an Income Transfer Device
质疑生命线电价作为向低收入家庭转移援助的有效性和公平性，认为社会保障、食品券等社会项目是更好的收入转移替代方案。
The lifeline electricity rates are presumed to be inefficient because they violate optimal pricing principles, but they may also be an ineffective and inequitable way to transfer assistance to low-income households. Evidence is presented to challenge the assumption that simple demand changes will permit high-consuming households to subsidize low-income users. Social security, food stamps, and other social programs are better alternatives to a general income transfer. 7 references, 2 tables. (DCK)
