Individual-level pay transparency narrows the gender pay gap only modestly while carrying significant workplace costs

The Gist
The author says letting workers see exactly what their colleagues earn would probably shrink the gender pay gap a bit, but at a cost. Pay could stop tracking performance, people on lower pay would get resentful and quit more, and overall wages might fall. He argues that published salary ranges and gender gap data are enough to expose unfairness.
Conclusion
The proposed right for UK workers to see individual co-workers' pay should be treated with caution, because the modest gains in gender pay equality it would likely bring come with real costs: weaker pay-performance links, resentment, higher turnover and lower overall pay. Aggregate measures like salary ranges in job ads and published gender gap data are the better approach.
Premises
- Existing aggregate transparency measures (gender pay gap reporting, salary reporting thresholds) have narrowed the gender pay gap, but largely by slowing men's pay growth or benefiting already highly paid or job-switching women, and they have not changed occupational sorting or productivity.
- Individual-level pay transparency has been shown to reduce the gender pay gap (e.g., 20-40% in Canadian universities), so the proposed policy would likely make women's and men's pay somewhat more equal.
- Individual-level transparency has also been shown to break the link between pay and performance, as less productive scientists ended up paid similarly to more productive peers.
- Individual-level transparency has been linked to lower overall wages and sharply higher quit rates (about 7% lower wages and a 75% increase in quit rates among Californian public sector top managers).
- Lower-paid employees who learn their colleagues' pay become more dissatisfied and more likely to job-hunt, while higher earners are unaffected, and modelling suggests transparency fuels unhealthy social comparison, anger and envy.
- Aggregate tools such as salary ranges in job ads plus published gender gap data already give employees enough information to spot and challenge unfairness.
Assumptions
- Findings from Canadian universities, US scientists, the Californian public sector and Nordic countries generalise to the broader UK labour market.
- Reduced pay-performance linkage, higher turnover, resentment and lower overall wages are genuine harms that outweigh modest gains in gender pay equality.
- Reductions in the gender pay gap that come from slower male pay growth are of limited value.
- Aggregate transparency is sufficient to detect and remedy unfair pay without individual-level disclosure.
- Employee dissatisfaction and quitting among lower-paid workers are costs to be avoided rather than possible signals of previously hidden unfairness being exposed.
