Automation with Heterogeneous Agents: the Effect on Consumption Inequality (submitted)
[Paper]
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.

Common Ownership and Automation - with Joseph Emmens, Dennis Hutschenreiter, Stefano Manfredonia and Felix Noth
We study the effect of increasing Common Ownership on Automation using a task-based model of Automation. We test the implication of our theoretical model on the US economy by combining common ownership data with patent data.

[Paper], [Appendix], [BGSE blog]
Empirical evidence in Dauth et al. (2021) suggests that industrial robot adoption in Germany has led to a sectoral reallocation of employment from manufacturing to services, leaving total employment unaffected. We rationalize this evidence through the lens of a general equilibrium model with two sectors, matching frictions, and endogenous participation. Automation induces firms to create fewer vacancies and job seekers to search less in the automatable sector (manufacturing). The service sector experiences a positive spillover effect due to the sectoral complementarity in the production of the final good and the positive income effect for the household. Analysis across steady states shows that the reduction in manufacturing employment can be offset by the increase in service employment. The model can also replicate the magnitude of the decline in the ratio of manufacturing employment to service employment in Germany from 1994 to 2014.
