The Broader interpretation that often seems to underlie the new economy label is that we are witnessing a more fundamental change in the paradigm. The old rules no longer apply. Throw out the NAIRU. Heck, throw out supply and demand. No limits, no business cycles.

There are broader and narrower definitions of the new economy. The narrow version defines the new economy in terms of two principal developments: first, an increase in the economy's maximum sustainable growth rate and, second, the spread and increasing importance of information and communications technology.
