Among the factors contributing to the success of the U.S. economy over the past decade—as reflected in the doubling of productivity growth compared to the preceding two decades—is the continued transformation of the U.S. economy toward a more entrepreneurial form of capitalism. In such a system, innovative new firms play an unusually central role in developing and commercializing the radical technologies that provide the underpinnings to whole new ways of doing things and enjoying life. In the last century, innovations which have changed the social and economic landscape in the United States and in much of the rest of the world such as the automobile, airplane, air conditioner, the personal computer and its operating system, and, most recently, many of the leading Internet-based business models, all were commercialized by entrepreneurs. http://www.nercrd.psu.edu/EntreCOP/Entrepreneurial_Roadmap_web.pdf
