我们使用美国的管理数据，研究了工人收入增长的分布如何随着公司或其竞争对手的重大技术进步而发生变化。具体来说，我们发现，自己的公司创新与工人收入增长的适度增加，而竞争对手的公司的创新与未来工人收入较低。重要的是，这些收入变化在工人中分布不对称：收益和损失都集中在一部分工人身上，这意味着工人收入增长率的分布在公司或其竞争对手的创新之后变得更加向右或向左倾斜。这些影响对收入最高的工人来说尤其强烈。我们的研究结果表明，创新与劳动收入风险的大幅增加有关，特别是对于处于收入分配顶端的工人。我们的模拟结果显示，20世纪90年代各公司创新成果的差异增加可以解释收入不平等上升的重要部分。总而言之，我们的证据与创新通过产品市场的创造性破坏和人力资本的置换导致劳动收入在工人之间的实质性重新分配的观点是一致的。
We examine how the distribution of worker earnings growth shifts following major technological advances by the firm, or its competitors, using administrative data from the US. Specifically, we find that own firm innovation is associated with a modest increase in worker earnings growth, while innovation by competing firms is related to lower future worker earnings. Importantly, these earnings changes are asymmetrically distributed across workers: both gains and losses are concentrated on a subset of workers, which implies that the distribution of worker earnings growth rates becomes more right- or left-skewed following innovation by the firm, or its competitors, respectively. These effects are particularly strong for the highest-paid workers. Our results suggest innovation is associated with a substantial increase in the labor income risk, especially for workers at the top of the earnings distribution. Our simulations reveal that the increased disparity in innovation outcomes across firms in the 1990s can account for a significant part of the rise in income inequality. In sum, our evidence is consistent with the view that innovation leads to substantial reallocation in labor income across workers through creative destruction in the product market and displacement of their human capital.
