This is an emerging literature that's really taken off in the last 20 years. Increasingly, statistical evidence shows that when you have greater levels of innovation, you get economic growth, because it enables the industry locally to use that innovation to bring down its costs or increase standards.
So innovation goes to sometimes just cost reduction, which passes through the system, or it makes the materials better, and therefore we're able to get for every dollar of investment a better product or cheaper product. That's the basic link.
