September 2011 Report

September 28th, 2011

 

On this website we publish our recession probability estimates and forecasts for the US economy obtained using the methodology in Paap et al. (2009), as described below. The website is updated every month, shortly after the release of The Conference Board's Coincident Economic Index (CEI) and Leading Economic Index (LEI).

Figure 1. Recession Probabilities for the US Economy

 

Figure 1 shows recession probability estimates over the last ten years up to August 2011. These are based on the CEI and LEI vintages released on September 22nd.

   

The CEI increased 0.1 percent in August to 103.3 (2004 = 100), following a 0.1 percent increase in July, and a 0.2 percent increase in June. The LEI increased 0.3 percent in August to 116.2 (2004 = 100), following a 0.6 percent increase in July and a 0.3 percent increase in June.

   

For the 23rd subsequent month, both the coincident recession probability and the leading recession probability remained constant at 0.0 percent. Despite the slowdown in the rate of increase of the leading and coincident indexes, there is no indication yet that the current expansion is likely to end in the near future.

 

The probabilities are obtained from a Markov-Switching model for monthly growth rates for the CEI and LEI. The model assumes that the two variables share the same cycle, where the LEI leads the CEI with lead times at peaks and troughs allowed to be different. The model therefore produces both a 'coincident' and a 'leading' recession probability.


Figure 2 shows coincident and leading recession probabilities since January 1959. The blue and green shaded areas indicate months that are part of periods during which this probability exceeds 0.5 for at least six consecutive months. This corresponds with the popular rule of thumb saying that the economy is in recession whenever economic growth is negative during two consecutive quarters. The recession periods as determined by the NBER are also shown for comparison.

Figure 3 displays the time series plots of the log levels and monthly growth rates of the LEI and CEI, together with the recession periods as determined by the NBER, indicated by the yellow shaded areas. The leading index has a similar cyclical pattern as the coincident index, but with turning points clearly occurring earlier, and recessions lasting considerably longer.
