Since its introduction as a concept, organizational stigma has become central to explaining how organizations or industries become tainted, and how they overcome and manage such taint. In this introduction to the Special Issue on organizational stigma, we start by exploring the origins of the concept, providing basic definitions and reviewing the existing research on stigmatization, stigma transfer and experienced stigma. The papers in this issue flesh out our understanding of what causes organizational stigma and its implications at different levels. The remainder of this introduction takes stock of this recent work to explore future research opportunities around the micro- and macro-foundations of organizational stigma, the links with scandals, controversies and other negative social evaluations and research methods. As the concept of organizational stigma reaches a new stage, we argue that its explanatory power can be harnessed to explore new and increasingly relevant phenomena and contexts.
