Joanne TAN (Sciences-Pô) – “Multidimensional Heterogeneity and Matching in a Frictional Labor Market – An Application to Polarization”
Abstract: Wage and job polarization are two defining phenomena that have characterized the US labor market from the 1980s to the late 2000s. Yet, men and women have had different polarization experiences. This paper proposes a model that accounts for these facts. The model has two key ingredients: 1) directed search and 2) multidimensional heterogeneity for workers and rms. Upon estimating the model, I find that, over time, the complementarity between cognitive skills and tasks increased relative to that between the interpersonal and manual skills and tasks. via the two aforementioned ingredients, this change induces polarization in the model. It also generates an improvement in sorting between workers and firms in the cognitive dimension relative to other dimensions, in line with the data. Moreover, it accounts for a large part of gender differences in polarization, despite the model being gender-blind. Lastly, in this novel framework of directed search with multidimensional heterogeneity, I develop a de_nition of assortative matching and examine the conditions under which it is obtained
