Job postings in Colorado and New York now have to show a real number, not a euphemism. State law requires a salary range, and new labor-market research on those postings finds wages rose roughly 1.3% to 3.6% after the requirement took hold — with no measurable dent in the gender or racial pay gap.
That gap between the sales pitch for these laws and what the data actually shows is worth sitting with, because pay transparency has become one of the most consequential — and least understood — shifts in how American companies hire. It's no longer a niche compliance detail buried in an HR memo. It shows up the moment a candidate opens a job board, and it's already changing how postings get written and how recruiters negotiate.
What does a job posting actually have to show now?
The requirements vary by state, but the core mechanics are similar. Colorado's Equal Pay for Equal Work Act requires employers to include compensation, benefits, and application deadlines in job postings, and to keep job-description and wage-rate records, according to the state Department of Labor and Employment. New York's pay transparency law, which applies to private employers with four or more employees, requires a listed compensation range — either an annual salary range or an hourly rate — for job postings, promotions, and transfers, and requires employers to say plainly if a role is commission-based, per the state Department of Labor.
Both states also protect workers who ask about pay. Colorado's rules require employers to notify existing employees of job opportunities, and New York's law bars retaliation against an employee or applicant who requests compensation information.
Does posting a range actually raise pay?
This is the part the data backs up. A November 2025 National Bureau of Economic Research working paper by David Arnold, Simon Quach, and Bledi Taska studied state-level pay-transparency mandates using a difference-in-differences design across three separate datasets. Employers' salary disclosure in postings rose by roughly 30 percentage points after the laws took effect, and wages climbed 1.3% to 3.6% in the affected postings — a gain the researchers attribute to sharper competition among employers once pay is visible, not to any single company's generosity.
The paper also found something that should temper the optimism: no measurable effect on the number of job postings, employment levels, or the skill and education requirements listed for those jobs. In plain terms, employers didn't quietly ask for more qualifications or post fewer jobs to offset the cost of higher pay — at least not in a way the researchers could detect.
So does it close the pay gap?
Not according to this research. The NBER paper found no measurable effect on pay inequality alongside the wage gains — a distinct claim from raising overall pay, and one that undercuts a common assumption behind these laws. Transparency appears to work as a competition mechanism that lifts wages generally, not as a targeted fix for gaps between groups of workers. Anyone selling pay transparency as a gender-pay-gap solution is telling a cleaner story than the evidence supports.
What happens if an employer doesn't comply?
Both states build in a path for workers to flag violations rather than leaving enforcement purely reactive. Colorado directs complaints through its Division of Labor Standards and Statistics, and requires employers to retain job-posting and wage records that regulators can review. New York directs complaints to its Division of Labor Standards, reachable through a dedicated hotline. Neither agency's public guidance pages reviewed here list a specific dollar penalty schedule, so job seekers checking a state's exact fine structure should go to that state's labor department directly rather than assume Colorado's and New York's numbers are interchangeable — the mechanics above are shared, the enforcement details are not.
What this means for how people job-hunt now
For workers in states with these laws, a posted range is now a piece of information to actually use — in salary negotiations, in deciding whether to apply, in comparing offers. For workers elsewhere, the research still matters: it's evidence, not just a talking point, that requiring a number on the page changes employer behavior in a measurable, generally upward direction. It just doesn't, on its own, do the harder work of closing the gap between who gets paid what.
It also reframes a common negotiating fear. Job seekers often worry that asking about pay will read as pushy or presumptuous. In states with these laws, the number is already sitting in the posting — the conversation has effectively started before anyone applies. That doesn't remove the discomfort some candidates feel raising it out loud, but it changes what's actually at stake in doing so.
