Why Wealth Taxes Are Not Enough

The IMF is right – on grounds of both fairness and efficiency – to raise the idea of temporary wealth taxes in many countries. But, as appealing as such taxes may seem at first sight, a closer look reveals that the revenues are lower, and the costs higher, than calculations used to promote them would imply.

CAMBRIDGE – Should advanced countries implement wealth taxes as a means of stabilizing and reducing public debt over the medium term? The normally conservative International Monetary Fund has given the idea surprisingly emphatic support. The IMF calculates that a one-time 10% wealth levy, if introduced quickly and unexpectedly, could return many European countries to pre-crisis public debt/GDP ratios. It is an intriguing idea.

The moral case for a wealth tax is more compelling than usual today, with unemployment still at recession levels, and with deep economic inequality straining social norms. And, if it were really possible to ensure that the wealth levy would be temporary, such a tax would, in principle, be much less distortionary than imposing higher marginal tax rates on income. Unfortunately, while a wealth tax may be a sound way to help a country dig out of a deep fiscal pit, it is hardly a panacea.

For starters, the revenue gains from temporary wealth taxes can be very elusive. The economist Barry Eichengreen once explored the imposition of capital levies in the aftermath of World Wars I and II. He found that, owing to capital flight and political pressure for delay, the results were often disappointing.

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
