Note from dshort: This commentary has been revised to include today’s release of Industrial Production and yesterday’s Retail Sales adjusted with today’s release of the Consumer Price Index.
Official recession calls are the responsibility of the NBER Business Cycle Dating Committee, which is understandably vague about the specific indicators on which they base their decisions. This committee statement is about as close as they get to identifying their method.
There is, however, a general belief that there are four big indicators that the committee weighs heavily in their cycle identification process. They are:
- Industrial Production
- Real Personal Income (excluding transfer payments)
- Real Retail Sales
The weight of these four in the decision process is sufficient rationale for the St. Louis FRED repository to feature a chart four-pack of these indicators along with the statement that “the charts plot four main economic indicators tracked by the NBER dating committee.”
Here are the four as identified in the Federal Reserve Economic Data repository. See the data specifics in the linked PDF file with details on the calculation of two of the indicators.
The FRED charts are excellent. They show us the behaviour of the big four indicators currently (the green line) as compared to their best, worst and average behaviour across all the recessions in history for the four indicators (which have start dates). Their snapshots extend from 12 months before the June 2009 recession trough to the present.
The Latest Indicator Data: Industrial Production and Real Retail Sales
This morning I’ve added two more of the Big Four for November: Industrial Production from the Federal Reserve, the purple line in the chart below and Real Retail Sales, the green line.
The Fed update on IP lead with the following observation:
Industrial production increased 1.1 per cent in November after having fallen 0.7 per cent in October. The gain in November is estimated to have largely resulted from a recovery in production for industries that had been negatively affected by Hurricane Sandy, which hit the Northeast region in late October. In November, manufacturing output increased 1.1 per cent after having decreased 1.0 per cent in October; in addition to the storm-related rebound, a sizable rise in the production of motor vehicles and parts boosted factory output in November. [Link] For a detailed overview of the latest Retail Sales, see my latest update, which I’ve revised to include today’s release of the November CPI.
Current Assessment and Outlook
At this point, the average of the Big Four (the grey line in the chart above) shows us that economic expansion since the last recession had been hovering around a flat line for the past several months. But the November data for Employment, Industrial Production and Real Retail Sales have shown improvement.
As for the recent data, of course they are subject to revision, so we must view these numbers accordingly.
The behaviour of all four of these indicators will be critical as move from the fourth quarter to the new year. Superstorm Sandy has not been traumatic to the economy, and we will see some positive effects from rebuilding in the impacted areas. Holiday season sales will be something to watch in the next Retail Sales release.
On the negative side, the continuing weakness in Real Personal Income Less Transfer Payments is a looming threat, and we may see evidence of it in the final tally of holiday spending. Finally, of course, the outcome of Fiscal Cliff negotiations remains a near-term worrisome wild card in the economic hand.
Background Analysis: The Big Four Indicators and Recessions
The charts above don’t show us the individual behaviour of the Big Four leading up to the 2007 recession. To achieve that goal, I’ve plotted the same data using a “per cent off high” technique. In other words, I show successive new highs as zero and the cumulative per cent declines of months that aren’t new highs. The advantage of this approach is that it helps us visualise declines more clearly and to compare the depth of declines for each indicator and across time (e.g., the short 2001 recession versus the Great Recession). Here is my own four-pack showing the indicators with this technique.
Now let’s examine the behaviour of these indicators across time. The first chart below graphs the period from 2000 to the present, thereby showing us the behaviour of the four indicators before and after the two most recent recessions. Rather than having four separate charts, I’ve created an overlay to help us evaluate the relative behaviour of the indicators at the cycle peaks and troughs. (See my note below on recession boundaries).
The chart above is an excellent starting point for evaluating the relevance of the four indicators in the context of two very different recessions. In both cases, the bounce in Industrial Production matches the NBER trough while Employment and Personal Incomes lagged in their respective reversals.
As for the start of these two 21st century recessions, the indicator declines are less uniform in their behaviour. We can see, however, that Employment and Personal Income were laggards in the declines.
Now let’s look at the 1972-1985 period, which included three recessions — the savage 16-month Oil Embargo recession of 1973-1975 and the double dip of 1980 and 1981-1982 (6-months and 16-months, respectively).
And finally, for sharp-eyed readers who can don’t mind squinting at a lot of data, here’s a cluttered chart from 1959 to the present. That is the earliest date for which all four indicators are available. The main lesson of this chart is the diverse patterns and volatility across time for these indicators. For example, retail sales and industrial production are far more volatile than employment and income.
History tells us the brief periods of contraction are not uncommon, as we can see in this big picture since 1959, the same chart as the one above, but showing the average of the four rather than the individual indicators.
The chart clearly illustrates the savagery of the last recession. It was much deeper than the closest contender in this timeframe, the 1973-1975 Oil Embargo recession. While we’ve yet to set new highs, the trend has collectively been upward. But a closer look at the average shows a clear slowing of the trend in 2012.
Appendix: Chart Gallery with Notes
Each of the four major indicators discussed in this article are illustrated below in three different data manipulations:
- A log scale plotting of the data series to ensure that distances on the vertical axis reflect true relative growth. This adjustment is particularly important for data series that have changed significantly over time.
- A year-over-year representation to help, among other things, identify broader trends over the years.
- A per cent-off-high manipulation, which is particularly useful for identifying trend behaviour and secular volatility.
The US Industrial Production Index (INDPRO) is the oldest of the four indicators, stretching back to 1919. The log scale of the first chart is particularly useful in showing the correlation between this indicator and early 20th century recessions.
Real Personal Income Less Transfer Payments
This data series is computed as by taking Personal Income (PI) less Personal Current Transfer Receipts (PCTR) and deflated using the Personal Consumption Expenditure Price Index (PCEPI). I’ve chained the data to the latest price index value.
The “Tax Planning Strategies” annotation refers to shifting income into the current year to avoid a real or expected tax increase.
Total Nonfarm Employees
There are many ways to plot employment. The one referenced by the Federal Reserve researchers as one of the NBER indicators is Total Nonfarm Employees (PAYEMS).
Real Retail Sales
This indicator is a splicing of the discontinued retail sales series (RETAIL, discontinued in April 2001) spliced with the Retail and Food Services Sales (RSAFS) and deflated by the Consumer Price Index (CPIAUCSL). I used a splice point of January 1995 because that was date mentioned in the FRED notes. My experiments with other splice techniques (e.g., 1992, 2001 or using an average of the overlapping years) didn’t make a meaningful difference in the behaviour of the indicator in proximity to recessions. I’ve chained the data to the latest CPI value.
Real Manufacturing and Trade Sales
This indicator is a splice of two seasonally adjusted series tracked by the BEA. The 1967-1996 component is SIC (Standard Industrial Classification) based and the 1997-present is NAICS (North American Industry Classification System) based. The data are available from the BEA website. See Section 0 – Real Inventories and Sales and look for Tables 2AU and 2BU. The FRED economists use the Real Retail Sales above for their four-pack. However, ECRI appears to use this series as their key indicator for sales. Note that the Manufacturing and Trade Sales data is updated monthly with the BEA’s Personal Consumption and Expenditures release, but the numbers lag by one month from the other PCE data.
Note: I represent recessions as the peak month through the month preceding the trough to highlight the recessions in the charts above. For example, the NBER dates the last cycle peak as December 2007, the trough as June 2009 and the duration as 18 months. The “Peak through the Period preceding the Trough” series is the one FRED uses in its monthly charts, as explained in the FRED FAQs illustrated in this Industrial Production chart.
