Title:
How Fast, in What Ways, and in What Order Do Firms Adjust to Minimum Wage Hikes? High-Frequency Evidence from Spot Labor Markets
Abstract:
This paper examines which margins firms adjust after minimum-wage hikes, in what order, and how quickly. Using contract-level data from a large spot-work platform and a wage-bin difference-in-differences, we find a 2\% employment decline in affected bins. We uncover a new low-cost channel: firms post earlier and adjust job descriptions, widening candidate pools and signaling desired skills--consistent with targeting more productive workers. Costlier amenities adjust later and modestly: transportation reimbursement rises slightly after 1-2 months, plausibly to broaden geographic reach, while staff-meal provision is unchanged. The sequence indicates rapid compliance, limited benefit offsets, and short-run incidence borne largely by establishments.
