Widespread unethical corporate misconduct in an industry triggers industry-wide crises. This research investigates how industry misconduct affects consumers’ trust in the industry, by incorporating insights from a micro-level psychological aspect of institutions. The conceptual framework proposes that consumer legitimacy judgement lies at the core of industry trust, following an industry-wide crisis. The results demonstrate that perception of normalisation of misconduct affects industry trust through consumer legitimacy judgement. Moreover, the PNM-CLJ-industry trust relationship is stronger during industry-wide crises compared with crises that (...) involve only one firm, and this relationship is not dependent on the frequency of crises. This research contributes to the knowledge of product-harm crisis by deepening understanding of the trust erosion mechanism during industry-wide crises, with a focus on legitimacy judgement. The findings have implications for prevention of industry-wide crises and for boosting ethically desirable business activities. (shrink)
