Lerner markets for equal work equal pay reducing wage dispersion by job category

How could a meta market for wage setting markets be built To gradually squeeze out wage dispersion While raise wage rates over time for each job type Goal a system that over time tended To uniformly Equalize .... system wide wage rates.... for Identical task bundles ............. ..... . A set of tasks may vary in proportions And task unit based rates look daunting The point would be to charge a fee for non equal rates for equal work Transparency is done qua non Of course But an equal pay board would set The categories and monitor compliance Imagine a warrant not to comply Would have a cost to employers Of course paying above norms would be rewarded Each off setting the other in total Hence the warrant exchange Much like exports dictating the size of imports
