The GDP Mirage: Why The Data Are Wrong

Shellabarger, an engineer working on future products, was nonetheless laid off by Autoliv Michael Nemeth/Wonderful Machine

Here's a riddle: If a scientist or engineer is laid off, does it affect gross domestic product?

The third-quarter GDP figures, released on Oct. 29, showed the economy growing at a 3.5% annual pace, breaking a string of four consecutive negative quarters. The growth was driven mostly by a surge in the production of motor vehicles and other manufactured goods.

This number was greeted by many economists and journalists as confirmations that the recession is over. What's more, the rise in real GDP, combined with a sharp fall in employment in the third quarter, implies that productivity also soared during the period. Good news, right?

The trouble is that those GDP and productivity growth figures could be significantly overestimated—perhaps by one percentage point or even more.

That's because the official statistics are not designed to pick up cutbacks in "intangible investments" such as business spending on research and development, product design, and worker training. There's ample evidence to suggest that companies, to reduce costs and boost short-term profits, are slashing this kind of spending, which is essential for innovation. Without investment in intangibles, the U.S. can't compete in a knowledge-based global economy. Yet you won't see that plunge reflected in the GDP and productivity statistics, which are still too focused on more traditional sectors, such as motor vehicles and construction.

In effect, government statisticians are trying to track a 21st century bust with 20th century tools. Not only is that distorting the critical data that investors, policymakers, and corporate executives use to evaluate the economy, but it might also be creating a false sense of relief as Americans battle a brutal recession.

Here's a sobering sign that companies are robbing the future to pay for short-term profits: Over the past year, U.S. employment of scientists and engineers—the people who create the next generation of products and make the U.S. more competitive over the long term—has fallen by 6.3%, according to a BusinessWeek tabulation of unpublished data. Yet overall employment has fallen only 4.1%. "There are really bright people who are struggling to find a job," says Josh Albert, managing director at Klein Hersh International, an executive search firm for life scientists.

That's a big problem, because the output of such well-educated workers has become an increasingly important part of the U.S. economy in recent years. New research by Carol Corrado of the Conference Board and Charles Hulten of the University of Maryland, to be presented at the annual meeting of the American Economic Assn. in January, suggests intangible business investment came to roughly $1.6 trillion in 2007, compared with about $1.2 trillion spent on tangible assets such as machinery and buildings. In 1995 the two were roughly equal. Going back even further, tangible investments in 1985 were about 40% larger than intangibles.

The Bureau of Economic Analysis, the government agency that compiles the GDP figures, is taking steps to deal with the new realities. Software has been treated as investment since 1999, and the BEA plans to include R&D in the official GDP statistics in 2013, four years from now. But the agency acknowledges that other areas of intangible investment still need to be worked into the numbers. "We think it's important not to ignore the fact that R&D is only part of broader innovative activity," says BEA Director J. Steven Landefeld. For now, though, the U.S. is navigating through the downturn with fragmentary information.

While the statistics don't account for it, there's good reason to suspect intangible investments are falling. Companies are under pressure to cut costs by reducing R&D expenditures and deferring other crucial intangibles, notes Hulten. "Because these are expensed, it looks like a pure win," he says. "You are not seeing the benefits of the intangibles in the ­financial statements—only the costs."
