The International Dynamics of R&D and Innovation in the Long Run and in the Short Run
估计了OECD国家研发就业与专利申请之间的动态关系，检验知识溢出是否足以驱动内生增长，并量化国际知识对一国技术创新的短期与长期影响。
In this article we estimate the dynamic relationship between employment in R&D and generation of knowledge as measured by patent applications across OECD countries. In several recently developed models, known as 'idea-based' models of growth, the 'idea-generating' process is the engine of productivity growth. Moreover, in real business cycle models technological shocks are an important source of fluctuations. Our empirical strategy is able to test whether knowledge spillovers are strong enough to generate sustained endogenous growth and to estimate the quantitative impact of international knowledge on technological innovation of a country in the short and in the long run.
