Making the Invisible Hand Visible: Managers and the Allocation of Workers to Jobs

QJE 2026. Virginia Minni.

ABSTRACT Abstract: Why do managers matter for firm performance? This paper provides evidence of the critical role of managers in matching workers to jobs within the firm using the universe of personnel records from a large multinational firm. The data covers 200,000 white-collar workers and 30,000 managers over 10 years in 100 countries. I identify good managers by their speed of promotion and leverage exogenous variation induced by the rotation of managers across teams. I find that good managers cause workers to reallocate within the firm through lateral and vertical transfers and generate large and persistent gains in workers’ career progression and productivity. My results imply that the visible hands of managers match workers’ specific skills to specialized jobs, leading to an improvement in the productivity of existing workers that outlasts the managers’ time at the firm.

The data and clean design of the paper is very impressive — though I’m not a labor-economic expert, having access to personnel records from a multi-billion-euro company is certainly not a piece of cake for any field. The paper shown by clean data analysis design that (i) Exposure to good manager causes workers to be reallocated to better-matched jobs and (ii) this mechanism dominates other explains such as those managers are more pushy or better teachers.

Prof Minni also talked about in Q&A that the identifying the very idea that she wants to test using data come from when talking to real managers about their managing philosophy.
