我们使用新的跨国企业生产、工资和研发投资数据，对包括美国在内的14个经合组织国家的标准生产函数进行了估算。数据样本涵盖1960-2004年。数据表明，增长差异在很大程度上可以由资本深化和以新专利形式生产新技术的能力来解释。我们还发现了专利和经济开放之间的互补性的强有力证据，但几乎没有证据表明随着时间的推移，替代弹性会增加。
We estimate standard production functions with a new cross-country data set on business sector production, wages and R&D investment for a selection of 14 OECD countries including the US. The data sample covers years the 1960–2004. The data suggest that growth differences can largely be explained by capital deepening and the ability to produce new technology in the form of new patents. We also find strong evidence of complementarity between patents and openness of the economy, but little evidence of increasing elasticity of substitution over time.
