- Rebecca Kehoe, professor of Human Resources Studies at Cornell's ILR School, found that each prior job change reduces the initial performance drop and speeds recovery when starting a new role — a 'mobility benefit' that accumulates with experience.
- The benefit is strongest when a new role involves a significantly different workplace culture or a group of long-tenured colleagues, precisely the situations where the 'shock' of starting over would normally be greatest, per the study.
- In highly collaborative roles, frequent job changers showed a smaller initial performance drop, but did not recover to prior performance levels any faster than less-mobile peers.
- The study, published in the Academy of Management Journal with co-author F. Scott Bentley of Rutgers, analyzed monthly performance data on more than 8,500 hedge fund managers across over 2,000 U.S. firms over 15 years, using mobility data stretching back another decade.
- Researchers measured performance using funds' Sortino ratios and concluded that learning to navigate a new organization's social landscape is a form of transferable 'human capital' that carries across jobs.
- Kehoe recommends hiring managers favor candidates with varied job histories when quick onboarding and immediate effectiveness matter, especially for collaborative roles or positions joining an established team.
Why it matters: Hiring managers often treat a long job-hopping history as a red flag, but Kehoe's findings suggest they should weigh it as a signal of adaptability in roles where ramp-up speed and cross-cultural fluency are at a premium. For workers, the takeaway is concrete: the ability to read and adjust to a new workplace's unwritten rules is a portable skill, not just a side effect of moving around.
