好不平等性与坏不平等性

普林斯顿—在经济理论中,平等与效率的权衡占据着崇高地位。美国经济学家亚瑟·奥肯(Arthur Okun)著有经典名著《平等与效率:大权衡》(Equality and Efficiency: The Big Tradeoff),他认为公共政策就是围绕管理这两种价值的冲突而生的。2007年,纽约大学经济学家托马斯·萨金特(Thomas Sargent)在为加州大学伯克利分校学生发表毕业演说时总结了12条简短的经济学原理智慧,权衡也在其中。

增进平等需要牺牲经济效率的观念建立在经济学最重要思想之一上:激励(incentives)。企业和个人需要有更高的收入前景才会储蓄、投资、努力工作和创新。如果盈利企业和富裕家庭的税收影响到这一前景,结果就是偷懒和经济增长下降。共产主义国家的平等主义实验往往导致经济灾难,一直是反再分配政策的“呈堂证供”。

但是,最近几年来,经济学理论和实证经验都倾向于这一假定的权衡。经济学家提出了新论据证明为何经济表现不仅相容于分配公平,甚至还有求于它。

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

    The Hungarian government has released the results of its "national consultation" on what it calls the "Soros Plan" to flood the country with Muslim migrants and refugees. But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
