The Huffington Post covered a paper appearing in this month's issue of the American Economic Journal: Applied Economics. In The Contribution of the Minimum Wage to US Wage Inequality over Three Decades: A Reassessment, the authors use updated data and a new methodological approach to study the link between wage inequality and the minimum wage. They find that a higher real minimum wage can reduce inequality, but that the effect is "substantially less" powerful than previously thought.
