经济刺激方案没有意义么?

哈佛大学经济学家罗伯特·巴罗在《华尔街日报》撰文反对美国经济刺激方案。在缺德的共和党人和无知的学术打手的操弄下,经济学的基本原理使得政府支出决策无法改变经济活动的运行方向,看了巴罗的文章使人松了一口气。

但我想,巴罗误读了其证据对我们目前情况的适用范围。巴罗写到,他“预计当年刺激方案的系数是 0.4 ,在两年内的系数是 0.6 。。。”税收的系数 1.1. 。。。由此得出, GDP 将在 2009 年增加 1200 亿美元, 2010 年增加 1800 亿美元。。。” 2011 年增加 600 亿美元。

这就意味着 2009 年美国增加 130 万多就业人口, 2010 年增加 190 万, 2011 年增加 70 万。想象政府的支出相当于私营经济支出的三分之二,这也是值得做的。在这种情况下,我们支出 6000 亿美元,收回 8100 亿美元的回报。社会净利润达到 2100 亿美元(对于那些失业人口就不能说想要休假而不愿意工作了。)

    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’s Failed Campaign of Lies

    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.
