NBER Working Paper by Gianluca Orefice and Giovanni Peri Released

A new working paper by GMC director Giovanni Peri and Gianluca Orefice has been released in the National Bureau of Economic Research. 

From the abstract: "Using French matched employer-employee (DADS) data over the period 1995-2005 we document that positive supply-driven changes of immigrant workers in a district increased the strength of PAM[positive assortative matching]. We then show that this association is consistent with causality, is quantitatively significant, and is associated with higher average productivity and firm profits, but also with higher wage dispersion. We also show that the increased degree of positive assortative matching is mainly reached by high-productive firms "losing" lower quality workers and "attracting" higher quality workers.
