Data released by Bank of America Merrill Lynch confirms that wages are rising in low-pay sectors. While the majority of the labor market is exhibiting wage growth of 2.4% year-on-year, the bottom 20% of industries is seeing growth of 3.4%. Analysts believe that there are two main drivers of this phenomenon: the increase of many state’s minimum wages and a very tight labor market for younger, less educated workers. Both California and New York boosted their minimum wages this year, impacting approximately 50% of the outperformance in the low-pay sector.
