The share of the nation's output that is conceptual appears to have accelerated following World War II with the insights that led to the development of the transistor and microprocessor. They have spawned remarkable alternations in how we, and other developed societies, live.

Computers, telecommunications, and satellite technologies have enabled data and ideas, the ever more important elements of output, to be speedily transferred geographically to where they can be put to best use. Thus, these advanced means of communication have added much the same type of value that the railroads added in transporting the more physical goods of an earlier century.

Here in the United States, we have developed an exceptionally sophisticated stock of capital assets- plant and equipment- fostered most recently by what has to be the most conceptual and impalpable of all new major products- software.

The breakthroughs in information technology have facilitated an elevated rate of 'creative destruction', as noted Harvard economist Joseph Schumpeter put it earlier this century. Our capital stock is undergoing an increasing pace of renewal through investment of cash flow from older technology capital facilities into new, more efficient vintages. Some Silicon Valley firms claim that they completely reconstitute themselves every year or two. This renewal process is driven by an increasing ability to more finely calibrate the value preferences of consumers. In turn, those preferences are converted, through market transactions, into prices of products and assets. They, in turn, signal entrepreneurs which capital facilities to build to meet those shifting consumer needs.
