Innovation
Innovation can be defined simply as a "new idea, device or method". However, innovation is often also viewed as the application of better solutions that meet new requirements, unarticulated needs, or existing market needs. Such innovation takes place through the provision of more-effective products, processes, services, technologies, or business models that are made available to markets, governments and society. The term "innovation" can be defined as something original and more effective and, as a consequence, new, that "breaks into" the market or society. Innovation is related to, but not the same as, invention, as innovation is more apt to involve the practical implementation of an invention (i.e. new/improved ability) to make a meaningful impact in the market or society, and not all innovations require an invention. Innovation often manifests itself via the engineering process, when the problem being solved is of a technical or scientific nature. The opposite of innovation is exnovation.
Market
Economists' usual list begins with distribution of income. There is no reason to believe that the distribution of income that emerges out of market processes is desirable or acceptable. Unbridled market forces without any role of government might lead to a large number of people living under subsistence. This is an area for government to do something. We know that unbridled economic forces can lead to big booms and big recessions. We need to do something about that. We know that a market can lead to pollution -- and there's an important role for government there. We know that there will be under-investment in public goods. As we think about the innovation economy, we should remember that most of the innovation in the private sector is based on research financed by the government, such as its role in developing the Internet.

Innovation
Successful innovation has consistently proved to be fluid and flexible, fast and furious — that is, passionate.
