We are pleased to be able to present, in this third volume of the Advances in Industrial and Labor Relations series, some original, important, and in some cases provocative research on industrial relations regulation, bargaining theory, progressive discipline, and occupational influences on unionism. In what follows we will briefly review each of the papers in the volume and pinpoint what we believe to be the major contributions each makes to the advancement of research in industrial relations. Where relevant, we will also mention questions left unresolved by the research at hand and potential directions for future research on the subjects under study.
