Too little U.S. innovation?

Has the U.S. economy suffered in recent years from a disappointing level of successful innovation?

BusinessWeek chief economist Michael Mandel makes a case in the current issue of BusinessWeek that the U.S. economy has experienced an “innovation shortfall” in the last decade — with successful commercialization of technological innovations slower to materialize than expected. The result, he suggests is an American economy that was weaker than it appeared. Writes Mandel:

“If the reality of innovation was less than the perception, that helps explain why America’s apparent boom was built on borrowing. ”
