But it would have been worse had it not been for the mysterious positive addition of 30,000 jobs by the so-called birth-death model. From here on out we’ll just refer to it as the birth-birth model because no matter how bad the underlying economic data this model somehow always adds jobs in every month except typically January and July when the model backs out a few of its more irrationally exuberant additions.
However, keeping regular track of the amount of fudging in the Birth-Death model is one of my favorite activities because I think it provides insight into just how unreliable government statistical models really are. For a nation that drives economic policy “by the numbers” it’s important that the numbers are good. The Birth-Death model provides a valuable caution flag for anyone with a tendency to “believe the numbers” that are being offered up for consumption.
