Steady Endogenous Growth with Population and R. & D. Inputs Growing
构建了一个熊彼特内生增长模型，在人口和研发投入增长时仍能实现恒定增长率的稳态，通过产品多样化抵消人口规模效应，并验证了研发补贴对增长的促进作用。
This paper presents a Schumpeterian endogenous growth model in which a steady state exists with a constant growth rate even though population and the inputs to R. & D. are growing. The scale effect of rising population is nullified by product proliferation that fragments the growing demand for intermediate prodcuts, thus preventing the reward to any specific innovation from rising with population. All the ususal comparitive statics results of Schumpeterian growth theory are valid, including the positive effect of R. & D. subsidies on growth.
