摘要

我们重新评估了知识产权产品资本化（IPP）在劳动收入占比下降中的作用。使用与Koh等人（2020）相同的美国汇总数据，我们表明，近几十年来，劳动收入占比明显下降，而且这种下降并不取决于IPP的资本化。KSLZ的方法估计了1929年至2018年期间的线性时间趋势，将IPP投资的逐步长期增长与近几十年来劳动收入占比的下降混为一谈。此外，在总体和行业数据中，我们都表明，IPP投资率的增长几乎完全被折旧所抵消。因此，净增加值的劳动份额及其近几十年来的下降对IPP资本化不敏感。

Capitalization of intellectual property products does not explain the decline in the labor share

We reevaluate the role of the capitalization of Intellectual Property Products (IPP) in the decline in the labor share. Using the same aggregate U.S. data as Koh et al. (2020), we show that the labor share has clearly declined in recent decades and that this decline does not depend on the capitalization of IPP. The approach of KSLZ, which estimates a linear time trend for the period 1929–2018, conflates a gradual and long-run increase in IPP investment with a decline in the labor share in recent decades. In addition, in both aggregate and industry data, we show that the increase in the rate of IPP investment is nearly fully offset by depreciation. As a consequence, the labor share of net value added and its decline in recent decades are insensitive to IPP capitalization.
