曼昆《经济学原理》第20章,Income Inequality and Poverty中有一句话,If benefits are phased out gradually as a poor family’s income rises, then families just above the poverty level will also be eligible for substantial benefits. The more gradual the phase-out, the more families are eligible,and the more the program costs.
这句话翻译好办,关键是怎么解释和理解。贫困家庭收入的增加,他们得到的利益就逐渐停止,那么贫困线上的家庭也将有资格获得巨大的利益。这句话怎么理解?贫困线上的家庭为什么也有资格获得(脱贫)利益?为什么利益越是逐渐停止,就有越多的家庭获得资格?
谢谢。
