我们开发了一个模型，在总体层面上，类似于单部门新古典增长模型；在分类层面上，它对可观察的技术采用措施的路径产生影响。我们使用过去两个世纪 15 种技术在 166 个国家传播的数据来估算。我们的研究结果表明，平均而言，各国在技术发明 45 年后才采用技术。不同技术和国家之间存在很大差异。新技术的采用速度比旧技术更快。技术采用方面的跨国差异至少占人均收入差异的 25%。 (JEL O33、O41、O47)
We develop a model that, at the aggregate level, is similar to the one-sector neoclassical growth model; at the disaggregate level, it has implications for the path of observable measures of technology adoption. We estimate it using data on the diffusion of 15 technologies in 166 countries over the last two centuries. Our results reveal that, on average, countries have adopted technologies 45 years after their invention. There is substantial variation across technologies and countries. Newer technologies have been adopted faster than old ones. The cross-country variation in the adoption of technologies accounts for at least 25 percent of per capita income differences.
