A new study by Ernst and Young is grabbing headlines by purporting to show that President Obama’s plan to end most of the Bush tax cuts for the richest 2% of Americans would cause job losses over the long term. This study is highly suspect however because it makes methodological assumptions that are out of line with other independent studies, which actually show that the expiration of the Bush tax cuts would lead to increased economic growth over the long term.
As the White House explains, the study assumes an entirely unrealistic drop in the labor supply by medium and high income earners due to higher tax rates. Their expected labor supply response is nearly 10 times higher than the non-partisan Congressional Budget Office (CBO) assumes when it makes similar estimates on labor supply effects.
In addition, the Ernst and Young study makes the bizarre assumption that all of the additional tax revenue will be used for additional spending, rather than for deficit reduction. While it does not explain any reason for this assumption, the effect of it is to eliminate the possibility that the additional revenue will increase private investment by reducing the deficit’s “crowding out” effect.
When the non-partisan CBO performed a study in January 2012 
on the economic effects of allowing the Bush tax cuts to expire using its much more robust assumptions, it found that the extension of all of the Bush tax cuts and other expiring measures would reduce Gross Domestic Product (GDP) by as much as 2.1 percent in 2022 and would reduce Gross National Product (GNP) by as much as 3.7 percent in 2022.
Building on this, Citizens for Tax Justice’s Bob McIntyre notes that even President George W. Bush’s own Treasury Department, which was “managed by Bush appointees who profess a deep affection for Bush’s tax-cutting policies,” found that over the long term extending the Bush tax cuts would have “essentially no beneficial effect on the U.S. economy at all.”
Ernst and Young’s reliance on a radical methodology, putting it out-of-line with even the Bush Administration’s Treasury Department, is not be much of a surprise considering that the study was paid for by conservative anti-tax groups like the US Chamber of Commerce and the National Federation of Independent Business. Both these groups have proven in the past that they are willing to distort the facts in order to protect the wallets of the country’s wealthiest corporations and CEOs.
