WASHINGTON — President Joe Biden signed an executive order Tuesday to increase the minimum wage to $15 an hour for federal contractors, providing a pay bump to hundreds of thousands of workers.

Biden administration officials said that the higher wages would lead to greater worker productivity, offsetting any additional costs to taxpayers.

“This executive order will promote economy and efficiency in federal contracting, providing value for taxpayers by enhancing worker productivity and generating higher-quality work by boosting workers’ health, morale, and effort,” the White House said in a statement.

The liberal Economic Policy Institute estimates that as many as 390,000 low-wage federal contractors would receive a raise, with roughly half of the beneficiaries being Black or Hispanic workers.

The increase could be dramatic for workers who earn the current minimum of $10.95 an hour. Those workers would receive a 37% pay hike, though the increase would be rolled out gradually, according to the terms of the order.

The White House said the workers would include cleaning professionals and maintenance workers, nursing assistants who care for veterans, cafeteria workers providing for the military and laborers who build and repair federal infrastructure.
