The Case for a Global Financial-Transaction Tax

Despite all economic pain caused by their recklessness, financial-market participants gained significant benefits from government bailouts. It is time for them to pay their fair share of the costs, and the most just and efficient way to ensure this is for the G-20 to implement a global financial-transaction tax.

BERLIN – What went wrong with global financial markets? In a nutshell: the implosion of the brave new world of modern finance, and the economic crisis that followed, was rooted in the idea that free and unregulated capital markets always work for the public good, and are all that is needed for economic prosperity. The prologue to the crisis was a combination of cheap money, deregulation, and a race for returns by executives undeterred by the associated risks.

When the housing bubble burst and financial markets collapsed in its wake, growth slumped worldwide as never before since the Great Depression. GDP in the advanced economies is expected to shrink about 4% this year. Total financial-sector losses in the world’s advanced economies stand at around $1.6 trillion. The IMF estimates that losses of more than double this total are yet to come. Jobs will continue to be shed. Future generations are being saddled with an explosion of public debt. It will take years before we recover fully.

Despite all this pain, the remaining financial-market participants gained significant benefits from government bailouts. The G-20’s average headline support for the financial sector is more than 30% of GDP (including capital injections, guarantees, treasury lending and asset purchases, liquidity provision, and other central bank support). In our political response to this crisis, new forms of financing and fiscal burden-sharing will have to play a role. It is in this context that German Foreign Minister Frank-Walter Steinmeier and I have advanced our proposal for a global financial-transaction tax (FTT).

    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.
