How about jobs? Brace yourself (details: 2007-2010; 2003-2006):

From 2007 to 2010, initial reports from the Bureau of Labor Statistics (BLS) told us that the economy lost 4.201 million jobs. BLS revisions have thus far ramped up the number of jobs lost by 2.43 million. The four-year total is now 6.631 million -- a stunning 58% increase. As seen above, the bureau's revisions to the 12 months of the real recession (July 2008 through June 2009) have shot reported job losses up by almost 1.9 million, a jaw-dropping average of 158,000 per month.

They're not done yet. Every February, BLS performs a comprehensive "benchmark revision." The next one will affect the period from March 2010 through December 2011. Considering the results of the past four years showing average additional job losses of 415,000, the next benchmark revision seems destined to push the figures even higher.

By contrast, from 2003 to 2006, initial BLS reports told us that the economy added 5.103 million jobs. After all revisions, the four-year total rose by 1.605 million to 6.708 million -- a 31% increase. The sum of all benchmark revisions during that time was a positive 675,000.

Why did the revised data largely improve (or at least decline very little) from 2003 through 2006, while decaying horribly since 2007? Frequent BizzyBlog commenter "JoeC" formulated the foundation of the negative side of what I call "revisionomics" almost four years ago, and worked up the positive side earlier this year. Paraphrased a bit, they are as follows:

  • First, there's "The Democrat Effect," which is "the rational response by entrepreneurs, businesspeople, and investors to imminent or already present excessive government intervention, overbearing regulation, crippling litigation, and taxation, all of which seriously curtail economic activity to a greater extent than initially estimated." When Democrats took full control of Congress in January 2007, initially reported economic news started to come in "unexpectedly" bad, and took serious turns for the worse when revised. Then, in the five months or so leading up to the 2008 presidential election, Pelosi, Obama and Reid deliberately frightened the economy's key players with promises of steep tax increases, wealth redistribution, government control of medicine, punitive regulation, and energy starvation. This led to the almost unimaginable recessionary data declines described above. Perhaps Bush 43 could have done something to stop the madness; sadly, he really didn't even try.

  • For what should be obvious reasons, the flip side of The Democrat Effect is not called "The Republican Effect." Its proper name is "The Conservative Effect," which is "the rational response by entrepreneurs, businesspeople, and investors when The Democrat Effect has either ended or is sufficiently reined in, enabling a reasonable level of free-market activity to occur, and causing the economy to perform better than initially estimated." From 2003 until 2006, the Bush administration's across-the-board income and investment-related tax cuts enabled The Conservative Effect to take hold in the job market, where initial results routinely and "unexpectedly" beat predictions, and subsequent revisions moved the numbers further upward. Unfortunately, the millions of hours of busywork caused by Sarbanes Oxley, as well as the onerous costs the law added to going public -- which caused and continues to cause growing firms which might have gone public in the U.S. before the law's passage to either decide against it overseas -- kept GDP growth, which could have been at least as strong as the late 1990s, at a mostly mediocre level.

Though they should, economic forecasters don't take the Democrat or Conservative Effect, whichever happens to be in force, into account when formulating their predictions. As long as this remains the case, and as long as the Obama administration stays on its current course of reckless spending, regulatory tyranny, and childish insistence on tax increases that will self-evidently make things worse, one does not need to possess psychic powers to know that we can count on "unexpectedly" bad economic news followed by additional, steep downward revisions.
