Last Tuesday, the Federal Reserve released the minutes of its October 30-31 Open Market Committee meeting, which for the first time included the projections for economic growth, unemployment, and inflation through 2010. I don’t recommend that you read the full report unless you are an economics geek like your friendly neighborhood blogger.
Here are the primary forecasts for 2008 made by Federal Reserve Governors and Reserve Bank Presidents:
- Real U.S. Gross Domestic Product (GDP) will grow between 1.8% and 2.5%
- The overall inflation rate will moderate somewhat between 1.8% and 2.1%
- The inflation rate excluding food and energy will range from 1.7% to 1.9%
- Unemployment will remain below 5%
These forecasts made me wonder: How is the growth of individual wholesale distribution sectors related to overall U.S. economic growth?
Wholesale distribution and GDP
To find out, I statistically correlated year-over-year growth in U.S. GDP to growth in the overall wholesale distribution industry. I used real, inflation-adjusted figures to compute growth rates.
The overall relationship shown in the chart below is very strong over time, although growth in wholesale distribution is more volatile than overall economic growth. (Click the charge to enlarge it.) The correlation of growth rates is 78%.

As I highlighted in
2007 Growth and the 2008 Economic Outlook, the wholesale distribution industry has been growing faster than the U.S. economy during the past three years.
GDP and Your Industry
Yet this overall correlation masks substantial variability between different sectors of the industry. So I statistically correlated year-over-year growth in U.S. GDP with growth in each of the nineteen sectors covered in 2007 Wholesale Distribution Economic Reports. Again, all data are adjusted for price changes.
As the table below illustrates, industrial sectors are more closely tied to the overall economic cycle, while staples such as food and drugs have little relationship to U.S. GDP. Surprisingly, revenue growth in the chemical and oil & gas sectors have little correlation to GDP growth due in part to the unusually close relationship between underlying commodity prices and revenues.

What’s Ahead for 2008? To learn more about the 2008 economic outlook for wholesale distribution and its primary sectors, please join me on my Wholesale Distribution Economic Outlook audio conference on Thursday, December 6.
You’ll be able to ask me real-time questions during this live event. You can also email me your 2008 economic questions in advance.

IN MEMORIUM: Erin Anderson
I am sad to report that Erin Anderson, a leading academic authority on distribution channels and co-author of the MBA textbook Marketing Channels
, passed away tragically last week. You can view the memorial page at INSEAD.
Erin was the intellectual and professional mentor who sparked my interest in wholesale distribution while I was a PhD student at Wharton. We also co-authored an academic paper on channel management and taught together in the Executive Education program at the Kellogg School. I would not be working in the industry, conducting research, or even writing this blog if not for Erin’s counsel, encouragement, and intellectual enthusiasm.
The Erin Anderson Excellence in PhD Education Fund has been established in recognition of her many contributions to student education. Please consider a tax-deductible contribution to this fund as a way to ensure support for high-quality academic research on distribution channels.
