研究表明，虽然R&D活动的规模影响制造业生产率的增长率，但生产率的增长率反过来又影响R&D的相对成本，从而影响R&D的需求。因为制造商的相对生产率和研发服务是决定其相对价格的关键。因此，研发的成功和随之而来的制造生产率的提高可能会提高研发的相对价格，减少需求数量。提供了这种反馈过程的正式模型，并展示了它如何导致振荡行为和经济长期生产率增长的放缓。
It is shown that while the scale of R & D activity affects the rate of growth of productivity in manufacturing, that rate of growth, in turn, affects the relative cost of R & D and, hence, its demand. For relative productivity of manufactures and R & D services are crucial in determining their relative prices. Thus, success in R & D and the consequent increase in manufacturing productivity may raise the relative price of R & D, reducing the quantity demanded. Formal models of this feedback process are provided and show how it can lead to oscillatory behavior an to a slowdown of the economy’s long-run productivity growth.
