We document that with each additional listing cohort, the U.S. public firm universe becomes more knowledge-intensive and, at the same time, more cost sticky. Higher reliance on temporary labor by newer listing cohorts partly mitigates this development. Our results call for the use of listing cohort-specific slopes to allow for cohort-specific estimates of cost stickiness in future research.engAsymmetric cost behaviorListing cohortsAdjustment costs330article10.1007/s00187-018-0263-3https://opus4.kobv.de/opus4-bamberg/frontdoor/index/index/docId/52699https://link.springer.com/article/10.1007/s00187-018-0263-3
