Studie zeigt Milliardenlücke im AfD-Programm für Sachsen-AnhaltReint GroppHandelsblatt, 6. August 2026
This paper studies whether common ownership affects the direction of technological change. We develop a task-based model in which commonly owned firms internalize wage externalities from labor market rivals, increasing incentives to automate. We establish causality by exploiting institutional investor mergers in a dynamic DiD design, using U.S. data on institutional ownership, establishment-level employment, and automation patents. When institutional investor mergers increase common ownership among labor market rivals, the annual probability of those firms producing an automation patent increases by 3.79 percentage points and employment growth falls by 3.8 percentage points on average. Both effects disappear without labor market overlap.
In this paper, I study technological change as a candidate for the observed increase in consumption inequality in the United States. I build an incomplete market model with educational choice combined with a task-based model on the production side. I consider two channels through which technology affects inequality: the skill that an agent can supply in the labor market and the level of capital she owns. In a quantitative analysis, I show that (i) the model replicates the increase in consumption inequality between 1981 and 2008 in the US (ii) educational choice and the return to wealth are quantitatively important in explaining the increase in consumption inequality.
