CBO’s Witch-Doctor Economics and Gypsy Forecasting
by Dan MitchellI’ve criticized the Congressional Budget Office for generating biased and inaccurate numbers. These are the clowns, after all, who say deficit spending stimulates the economy in the short run but they also rely on a model which seemingly predicts 100 percent tax rates maximize growth in the long run.
About the only nice thing that can be said about this collection of bureaucrats is that they’re consistent, though I’m not sure being wrong all the time is something to brag about – especially when even cartoonists start to make fun of CBO’s flawed approach.
This is why I’ve argued it may be best to shut down CBO and also written that – at a minimum – sweeping reform of the Capitol Hill bureaucracy is a test of GOP seriousness.
I’m not alone in my disdain for CBO. In a column for The Hill, Veronique de Rugy of the Mercatus Center makes two excellent points about the Congressional Budget Office: 1) the general inability of economists to predict (we’d be rich if we knew how to do that) and 2) the use of inaccurate models.
The CBO’s consistently flawed scoring of the cost of bills is used by Congress to justify legislation that rarely performs as promised and drags down the economy. Whether it scores the recent healthcare bill or the cost of the Capitol Hill Visitor Center, an ambitious three-floor underground facility, the price for taxpayers always ends up larger than originally predicted. …Like many economists, its analysts suffer from a misplaced belief in their forecasting prowess. …CBO relies heavily on Keynesian economic models, like the ones it used during the stimulus debate. Forecasters at the agency predicted the stimulus package would create more than 3 million jobs. …But unemployment stubbornly remained around 10 percent. What was wrong with the CBO’s numbers? …the stimulus and the ACA should serve as yet more evidence that Congress should take budget scores and economic projections with a grain of salt. What looks good in the spirit world of the computer model may be very bad in the material realm of real life because people react to changes in policies in ways unaccounted for in these models.
Let’s now move from the general to the specific. Peter Suderman reports from Reason on new research suggesting that costs for just one provision of Obamacare may be far higher than predicted by the jokers at CBO.
