Credit Spread Model Predicts Massive Job Losses

I find a lot of interesting ideas in the Wall Street Journal's "Heard on the Street" column, which is published daily on the back of the Money & Investing section. Today's lead article, Giving Corporate Credit Its Due, describes an economic model from a forthcoming research article by Simon Gilchrist, Vladimir Yankov, and Egon Zakrajsek. The model uses corporate credit spreads to forecast job market activity. Take a look at the chart, below, which compares nationwide hiring activity with the results of the authors' model.

The shaded green line shows the year-over-year percentage change in nonfarm payrolls. The blue line shows the corresponding prediction from the authors' model. Evidently, the model fits the historical data rather well.

There's a big difference between explaining the past and predicting the future. In other words, there's no guarantee that the model's predictions will be accurate. So much for the disclaimers. The current prediction is bleak. It calls for nonfarm payrolls to fall by 7.5% during calendar year 2009. Even if you assume that some of those job losses have already turned up in the official statistics, that would still take the unemployment rate well into double digits by the end of the year.

Reflecting on one of my earlier blog postings about jobs and home prices, this new model suggests that home prices will remain soft at least through the end of the year.

(By the way, a 'credit spread' is the difference between two interest rates, i.e., the rate that a corporate borrower pays and the rate that the government pays. Government debt is assumed to be free of default risk, while corporate debt exposes the holder to the possibility of not being repaid. The difference between the two interest rates encapsulates the bond market's estimation of the likelihood that the corporate borrower will default.)
