托宾麻烦

美国剑桥—欧洲领导人正在认真考虑托宾税,即对金融交易征收少量的税金,从而抑制交易。但这一税种能起到其鼓吹者所希望的效果吗?

这一税种(用已故诺贝尔经济学奖获得者詹姆斯·托宾的名字命名,他的初衷是减少货币市场上的汇率波动)大受支持反映了人们对金融部门的广泛敌意,但人们对其的支持度远远超过了该税种所能带来的好处。尽管如此,当选官员仍觉得托宾税具有相当大的吸引力,因为它能够让批评之声有所消停,还能把公众目光从经济政策(特别是预算、债务和增长疲软)等基本但又不具有政治可行性的问题上转移开去。

托宾税确实有诸多好处,尽管它不能充分解决困扰当今金融市场的全部问题。对股票交易征税能够鼓励人们长期持股。托宾税的征收对象是在很多人看来过于宽松的流动性。托宾税能鼓励人们分析公司经营的基本面,一些鼓吹者更是希望托宾税能促使企业自身更加专注于长期价值。

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
