The literature on labor relations has been very much divided, mainly between the classical economic approach and the legal/sociological one. An economic analysis of labor law would benefit by abridging both perspectives and complementing with more. This entry provides brief comments of why whether a purely economic approach on labor or a purely legal approach based on capital vs. labor dichotomy is not sufficient to properly address the subject. Several topics related to labor regulation are discussed, and empirical references on those issues are provided.
