To what extent are the effects of the minimum wage on hourly wages due to adjustments in gross income or working hours? What effects did the minimum wage have on wage inequality? How has wage mobility reacted to the statutory minimum wage? What impact did the minimum wage have on paid and unpaid extra hours? To what extent has the minimum wage affected multiple job holdings?
