α: calibrated so average coauthorship-adjusted count equals average raw count
Various reasons have been put forward to explain the stylized fact that the wages of job starters are more procyclical than the wages of workers who don't change jobs. I explore the theoretical and empirical basis for one such reason: firms adjust the quality of workers assigned to jobs over the business cycle. I show that there is evidence that quality adjustment is an important feature of cyclical adjustment in labor markets. New hires of any particular ability level get lower quality jobs in recessions than in booms. The results indicate that about half of the wage procyclicality of new hires can be ascribed to variation in the matches between firms and workers over the business cycle. These systematic changes in assignment imply that government policy aimed at high‐skill sectors can have positive effects on low‐skill individuals by increasing the probability that they upgrade occupation and industry.
