fueling inflation. Policy-makers previously focused almost entirely on changes in demand as the determinant of inflation, but the surge in productivity showed that changes on the supply side of the economy could be just as important and in some cases even more important.12 Such data serve to sustain the US commitment to invest substantial public funds in science and engineering.13
Of equal interest are studies of the rate of return on private investments in R&D.14 The return on investment to the nation is generally higher than is the return to individual investors (Table 2-2).15 One reason is that knowledge tends to spill over to other people and other businesses, so research results diffuse to the advantage of those who are prepared to apply them.
