The Brits -- and Paul Krugman -- are recommending a financial speculation tax. Tim Geithner and other "US officials" are opposed. Probably some are opposed because it sounds threateningly unfamiliar and uncapitalist, others because they're tied by increasingly visible lines to the banking and investment industry.
The dispute began back in August, when Adair Turner, Britain’s top financial regulator, called for a tax on financial transactions as a way to discourage “socially useless” activities. Gordon Brown, the British prime minister, picked up on his proposal, which he presented at the Group of 20 meeting of leading economies this month.
Why is this a good idea? The Turner-Brown proposal is a modern version of an idea originally floated in 1972 by the late James Tobin, the Nobel-winning Yale economist. Tobin argued that currency speculation — money moving internationally to bet on fluctuations in exchange rates — was having a disruptive effect on the world economy. To reduce these disruptions, he called for a small tax on every exchange of currencies.
Such a tax would be a trivial expense for people engaged in foreign trade or long-term investment; but it would be a major disincentive for people trying to make a fast buck (or euro, or yen) by outguessing the markets over the course of a few days or weeks. It would, as Tobin said, “throw some sand in the well-greased wheels” of speculation.
Many opposed to the tax say it's unworkable. Krugman counters that no, things have changed. The business of financial transactions has become increasingly centralized.
... While traders are all over the place, a majority of their transactions are settled — i.e., payment is made — at a single London-based institution. This centralization keeps the cost of transactions low, which is what makes the huge volume of wheeling and dealing possible. It also, however, makes these transactions relatively easy to identify and tax. ...
...Would a Tobin tax solve all our problems? Of course not. But it could be part of the process of shrinking our bloated financial sector. On this, as on other issues, the Obama administration needs to free its mind from Wall Street’s thrall.
Amen.
