An economy composed only of small, short-lived entities would be no more sustainable than an ecosystem composed only of insects. And the mere fact that an organization has existed for a long time or is engaged in a long-standing business does not make it "Old Economy" and therefore obsolescent. The key point is that organizations of all sizes and types have distinct roles to play in a creative economy. Small firms, big firms, the federal government, and nonprofit research universities all come into play in interlocking ways to develop and refine ideas and bring them to market. To borrow a concept from my colleague Ashish Arora, it is this very "division of innovative labor" that has spurred so much of our recent creativity.
