Low-skilled workers saw almost no wage growth from 2010-2014, but then experienced rapid catch-up growth from 2014-2018.
new paper (not peer reviewed yet) finds almost no nominal wage growth in low-wage jobs from 2010-2014, but then a catch up btw 2014-2018. over same time period time wages in high wage jobs grew at a steady rate.
"...In this paper, we introduce a concept of position specificity, where skilled workers are horizontally differentiated in the firm. In a frictional labor market with upward sloping retention functions, high-specificity workers are more costly to replace due to employers searching in thinner labor markets for a specific combination skills. This leads high-specificity firms to offer higher wages as average product at the firm rises, while also insulting workers in high-specificity positions from changes in labor market conditions....Figure 1 shows that wage growth in high wage occupations was nearly constant over these two periods, but wage growth in low-wage occupations was substantially lower in the early period but shows nearly perfect catch-up growth in the later period....Figure 2 plots employment growth by occupation over same period, showing that employment growth over these two periods are essentially identical for both high- and low-wage occupations. In addition to differences within business cycles, there is evidence that low-wage occupations' relative sensitivity to slack holds across business cycles as well...skilled workers appear to differential earn larger wage premia at more productive fi rms, not only in response to shocks to rm productivity, but also in the cross-section, thus reflecting long-term or steady state wage dispersion....We believe that this model provides insight into heterogenous wage setting decisions where it appears that different kinds of workers have different levels of “bargaining power”, as well as has the potential to help explain unresolved questions in the change of the distribution of wages in the last two business cycles. We conclude that the concept of position specificity can be useful for a wide range of questions in labor economics and may have important policy considerations for understanding and addressing wage inequality...."
