目的-本文的目的是研究美国的生产率增长和技术进步偏差。设计/方法/方式-科利在1978年和Diewert和威尔士在1992年的工作之后,本文估计产出供应和投入需求函数的背景下,一个规范化的二次(NQ)可变利润函数使用美国的数据(在1960年至2002年期间)对六种商品:产出,出口,进口,劳动力,可再生资本,固定资本。结果-结果表明,NQ可变利润函数与线性样条函数的工作非常好,用于确定结构性断裂的技术是有效的。估计表明,美国生产率在过去十年中逐步恢复,而不是像以前的一些研究所建议的那样在1996年一夜之间跃升,而且1995年后美国生产率的复苏是不稳定和脆弱的。原创性/价值-本文重点介绍了美国的生产力趋势。
Purpose – The purpose of this paper is to investigate productivity growth and technical progress bias in the USA. Design/methodology/approach – Following the work of Kohli in 1978 and Diewert and Wales in 1992, the paper estimates output supply and input demand functions in the context of a normalized quadratic (NQ) variable profit function using US data (over a period from 1960 to 2002) on six goods: output, exports, imports, labour, reproducible capital, and fixed capital. Findings – Results show that the NQ variable profit function with linear splines works very well and the technique for determining structural breaks is effective. Estimates show that the US productivity rate in the last decade recovered in a stepwise manner, rather than jumped overnight in 1996 (as some previous studies have suggested), and that the US productivity revival after 1995 has been volatile and fragile. Originality/value – This paper highlights productivity trends in the USA.
