Manufacturing Growth: Much Worse than We Thought

Posted by: Michael Mandel on June 05

According to the official statistics from the BEA, real manufacturing output, or value-added, grew at a 2.6% annual rate between 1998 and 2007. That’s barely a hair below the 2.7% growth rate for the entire economy.

More astonishingly, every major durable goods industry (with the exception of primary metals) grew over this stretch, despite massive increases in imports. How can this be?

The answer is: It can’t. The measurement of manufacturing growth was distorted by the problems with the import prices. I explain it all in my online story “Growth: Why the Stats Are Misleading”. Here’s an excerpt:

… new research by Emi Nakamura and Jón Steinsson of Columbia University suggests pervasive problems with the government’s import-price statistics. One example: Figures from the Bureau of Labor Statistics seem to show that the reported price of imported furniture rose by a total of 9% from 1998 to 2007. But how can the import price of furniture have risen over a stretch when the price paid by consumers fell by 7%? Or take computers. Official stats indicate that the price of computers for consumers fell at an average annual rate of 22% a year from 1998 to 2007, which seems to fit with personal experience. However, the import price index for computers shows a drop of only 8% per year over the same time, which seems unlikely. Similar problems occur for other imported consumer durables, including motor vehicles and parts.

Like a slow water leak that eventually erodes the foundation of a house, these apparently arcane import-price problems mean that the real growth of imports has been significantly underestimated for goods such as computers that have rapid model changes. That in turn distorts the productivity and growth stats, making them look a lot better than they really are. Adjusting for the finance bubble and the import-price problems means economywide productivity growth may have been about 1.3% per year rather than the reported 1.7%. Similarly, real growth of gross domestic product falls to roughly 2.3% annually from 2.7%. (The exact size of the downgrade depends on what is assumed about the correct change in import prices.)

That’s bad enough, but the real downgrade comes in the manufacturing sector. Official stats seem to show that U.S. manufacturing output grew at a 2.6% annual pace from 1998 to 2007, a strangely positive picture considering how many factory jobs were lost and how much production was shifted overseas. After the adjustments, however, the new growth rate for manufacturing output might be as small as 0.8% a year, and factory productivity growth becomes weaker as well. The conclusion: You can’t depend on productivity and output growth to make a case for strong innovation

This is a big deal. Take a look.

Good article: thanks for this. It clears up a bit of my cognitive dissonance between the qualitative and quantitative information I've been getting from different sources on manufacturing.

Michael, I am beginning to feel that the reason I am drawn to your blog is that you keep vindicating the notions I have but can't quite prove. Now that you've established that the manufacturing picture is just as ugly as I've suspected, here are a couple of other areas that, on the surface at least, seem to me to be out of whack and I wish you could address (not really requests to you, just fantasies or hopes that these areas might coincide with your areas of interest or journalistic need).

Most of the more or less unavoidable expenses of living have become normalized (i.e. have consistent cost) across the U.S. -- gasoline, heating fuel, electricity (?), health care (?), clothing, food. The single major expense that is highly responsive to locale seems to be housing. The difference in value for a house in an area where there are virtually no jobs versus a vital metro area can be astounding -- perhaps $50,000 versus $500,000 for essentially the same house. Because of thinning population in the somewhat destitute areas, property taxes are also dramatically disparate -- perhaps $500 versus $10,000 annually for that same house. Given these conditions, I suspect 2 things: 1) that the CPI presumes that everyone can take their share of the cost improvements, but perhaps, in reality, some cannot even pay for the cost of living where there is a job to be had (and thus cannot take advantage of the strides in technology and other costs encompassed by CPI) in any location except one where there are actually no jobs, and 2) that there is no standard of living that a person in the U.S. could reduce himself to and compete with foreign wages due to the U.S. cost of living. These are not easy questions. For instance, we have no figures regarding the necessary commute (often without the benefit of public transportation) for a teacher or retail clerk or busboy to serve where they cannot afford to live.

I only raise these questions because of the astounding number of locally employed people I've encountered who report that can no longer or never could afford to live nearby. On the other hand, when I try to calculate what it would cost a person to live minimally in the cheapest dump in the U.S. I keep concluding that it would cost them more than Chinese or Indian wages. It has broad, worrisome implications. It is ultimately a foreign exchange issue that leads to so many other questions.

Does this affect the "record" manufacturing output we had for the year 2007?

Joe:

Good question. I haven't run all the intermediate years, but I wouldn't be surprised to see 2000 turn out to be the peak. I'll do the calculation.

I need a little help with the basic concepts.

Michael writes, "Statisticians look at how much is bought by American consumers, companies, and governments, and by foreigner purchasers of U.S. exports. Then they subtract out imports. What's left is U.S. output, also known as domestic value-added, or production."

But then he goes on to write that inflated import prices help overstate production.

How can this be? If production = consumption - imports, and the value of imports is overstated, then wouldn't it follow that production is understated?

Hi Bill

Here's the key. The increase in real production is (roughly speaking) equal to the increase in real consumption minus the increase in real imports.
The increase in real imports is equal to the increase in nominal imports adjusted by the change in the price of imports.

So if import prices drop faster, then the increase in real imports is bigger, and the increase in real production is smaller.

Is there a viable way to correct this going forward? Can the BEA get the data required? It seems in the past global trade was not large enough compared to our domestic output for this to be an issue. Now, it's not just the trade deficit that we need to consider but also the size of Exports and Imports that matters (or the size of errors in these). Is there a similar error that can happen on the export side? Is there an error in real vs. nominal exports as well?

All this article highlights is the long-running stupidity of having govt bureaucracies try to "measure" the entire economy and then "manage" outcomes. What we should be doing is getting rid of these dumb agencies, not bumping their budgets.
