Reduced-form evidence reveals substantial adjustment frictions attenuating bunching and de-bunching responses. Combining the empirical bunch-ing moments with a structural model of frictional earnings supply, adjustment costs are estimated between EUR 93 and EUR 238 for wage earners. Moreover, we uncover important asymmetries in adjust-ment frictions, where bunching at a kink is costlier than de-bunching away from the kink. Finally, we find that self-employed individuals face considerably lower adjustment costs than wage earners.(c) 2022 Elsevier B.V. All rights reserved. 收起
