Consider two principles for social evaluation. The first, “laissez-faire”, says that mean-preserving redistribution away from laissez-faire incomes should be regarded as a social worsening. This principle captures a key aspect of libertarian political philosophy. The second, weak Pareto, states that an increase in the disposable income of each individual should be regarded as a social improvement. We show that the combination of the two principles implies that total disposable income ought to be maximized. Strikingly, the relationship between disposable incomes and laissez-faire incomes must therefore be ignored, leaving little room for libertarian values.

自由放任与帕累托

考虑社会评价的两个原则。第一个是“自由放任”，认为远离自由放任收入的均值再分配应被视为一种社会恶化。这一原则抓住了自由主义政治哲学的一个关键方面。第二种，弱帕累托，指出每个人可支配收入的增加应该被视为一种社会进步。我们表明，这两个原则的结合意味着总可支配收入应该最大化。引人注目的是，可支配收入和自由放任收入之间的关系因此必须被忽略，自由主义价值观几乎没有空间。
