Show Me The Money

A protegé of the French economist Thomas Piketty, Gabriel Zucman has researched the mystery of international balance sheets showing increasing liabilities: Where’s the money?

Rich people and cash-rich companies are hiding it in tax havens:

Jacques Leslie, The True Cost of Hidden Money

GABRIEL ZUCMAN is a 27-year-old French economist who decided to solve a puzzle: Why do international balance sheets each year show more liabilities than assets, as if the world is in debt to itself?

Over the last couple of decades, the few international economists who have addressed this question have offered a simple explanation: tax evasion. Money that, say, leaves the United States for an offshore tax shelter is recorded as a liability here, but it is listed nowhere as an asset — its mission, after all, is disappearance. But until now the economists lacked hard numbers to confirm their suspicions. By analyzing data released in recent years by central banks in Switzerland and Luxembourg on foreigners’ bank holdings, then extrapolating to other tax havens, Mr. Zucman has put creditable numbers on tax evasion, showing that it’s rampant — and a major driver of wealth inequality.

Mr. Zucman estimates — conservatively, in his view — that $7.6 trillion — 8 percent of the world’s personal financial wealth — is stashed in tax havens. If all of this illegally hidden money were properly recorded and taxed, global tax revenues would grow by more than $200 billion a year, he believes. And these numbers do not include much larger corporate tax avoidance, which usually follows the letter but hardly the spirit of the law. According to Mr. Zucman’s calculations, 20 percent of all corporate profits in the United States are shifted offshore, and tax avoidance deprives the government of a third of corporate tax revenues. Corporate tax avoidance has become so widespread that from the late 1980s until now, the effective corporate tax rate in the United States has dropped from 30 percent to 15 percent, Mr. Zucman found, even though the tax rate hasn’t changed.


Mr. Zucman’s tax evasion numbers are big enough to upend common assumptions, like the notion that China has become the world’s “owner” while Europe and America have become large debtors. The idea of the rich world’s indebtedness is “an illusion caused by tax havens,” Mr. Zucman wrote in a paper published last year. In fact, if offshore assets were properly measured, Europe would be a net creditor, and American indebtedness would fall from 18 percent of gross domestic product to 9 percent.

So, another wrinkle in the new abnormal economics: the wealthy can skew the system to pile their shekels higher and higher, meanwhile manipulating the system so that national policies reinforce the massive inequality of our economy.
