I'm not an economist, but I imagine it's similar to disclosing any product margin or cost of goods. It's probably more about what it does to the perception of the producer vs. the consumer. It may lead to increased cost (paying higher salaries) if the market is not competitive and companies are leveraging the obscurity. But it may decrease cost if things are over valued. The question is, is the labor market over or under valued? If it's over-valued then disclosing may actually cause salaries to equilibrate/come down -- which would be to the company's advantage. Does it imply that companies think the market is over-valued and aren't wanting to increase competition (both internally amongst current employees and externally with new hires)?
