New research by Growth Lab Research Director Frank Neffke assesses the importance of the skills of coworkers. Finding coworkers who complement and not substitute one’s skills can significantly impact earning potential. The impact is equal to having a college degree. Coworker complementarity also drives careers and supports urban and large plant wage premiums.
