Chart: Is That Robust U.S. Growth Imaginary?

Whenever critics of globalization complain about the loss of American jobs to low-cost countries such as China and India, supporters point to the powerful performance of the U.S. economy. And with good reason. Despite the latest slow quarter, official statistics show that America's economic output has grown at a solid 3.3% annual rate since 2003, a period when imports from low-cost countries have soared. Similarly, domestic manufacturing output has expanded at a decent pace. On the face of it, offshoring doesn't seem to be having much of an effect at all.

But new evidence suggests that shifting production overseas has inflicted worse damage on the U.S. economy than the numbers show. BusinessWeek has learned of a gaping flaw in the way statistics treat offshoring, with serious economic and political implications. Top government statisticians now acknowledge that the problem exists, and say it could prove to be significant.

The short explanation is that the growth of domestic manufacturing has been substantially overstated in recent years. That means productivity gains and overall economic growth have been overstated as well. And that raises questions about U.S. competitiveness and "helps explain why wage growth for most American workers has been weak," says Susan N. Houseman, an economist at the W.E. Upjohn Institute for Employment Research who identifies the distorting effects of offshoring in a soon-to-be-published paper.

The result? BusinessWeek's analysis of the import price data reveals offshoring to low-cost countries is in fact creating "phantom GDP"--reported gains in GDP that don't correspond to any actual domestic production. The only question is the magnitude of the disconnect. ...

By BusinessWeek's admittedly rough estimate, offshoring may have created about $66 billion in phantom GDP gains since 2003 (page 31). That would lower real GDP today by about half of 1%, which is substantial but not huge. But put another way, $66 billion would wipe out as much as 40% of the gains in manufacturing output over the same period.

It's important to emphasize the tenuousness of this calculation. In particular, it required BusinessWeek to make assumptions about the size of the cost savings from offshoring, information the government doesn't even collect.

But the new numbers also require a reassessment of productivity and wages that could add fire to the national debate over the true performance of the economy in President Bush's second term. The official statistics show that productivity, or output per hour, grew at a 1.8% rate over the past three years. But taking the phantom GDP effect into account, the actual rate of productivity growth might be closer to 1.6%--about what it was in the 1980s.

Yet no matter how hard you look, you can't find any trace of the cost savings from offshoring in the import price statistics. The furniture industry's experience is particularly telling. Despite the surge of low-priced chairs, tables, and similar products from China, the BLS is reporting that the import price of furniture has actually risen 6.7% since 2003.

The numbers for Chinese imports as a whole are equally out of step with reality. Over the past three years, total imports have climbed by 89%, as U.S.-based companies have rushed to take advantage of the enormous cost advantages. Yet over the same period, the import price index for goods coming out of China has declined a mere 2.3%. ...
