The rise of monopsonistic labor markets
Benmelech and al argue that the transmission of productivity growth into wage increases is greatly limited in labor markets where employers are more concentrated. These monopsonistic labor markets are the outcome of declining unionization and labor mobility in the US.

Self-selection
Borovíĉková and Shimer use an interesting measure of correlation, to show that high wage workers work for companies that pay high average wages, and that low wage workers work for companies that pay low wages. While an obvious observation it’s the first time it is found in the data.

The state of the labor market in the US and the Netherlands
The share of self-employed and temporary workers in total employment in the Netherlands has grown steadily from 16.6{5e7f07e14add20b2e04f4edb85a447d3cd8121fc27b809645e9fed603c22cc5c} in 1980 to 25{5e7f07e14add20b2e04f4edb85a447d3cd8121fc27b809645e9fed603c22cc5c} in 2000 and further to almost 38{5e7f07e14add20b2e04f4edb85a447d3cd8121fc27b809645e9fed603c22cc5c} in 2016. A recent study conducted by De Nederlandsche Bank shows that temporary employment and alternative working arrangements (mostly in the form of self-employment) are the main driver of low wage growth and a declining wage share. In the US the significant number of discouraged workers who stopped looking for work and dropped out of the statistics reached a peak of 3.9 million people in 2015. This fact suggests that we should look at the low unemployment statistic with a grain of salt.
