To date, theory and research on corruption in organizations have primarily focused on its static antecedents. This article focuses on the spread and growth of corruption in organizations. For this purpose, three downward organizational spirals are formulated: the spiral of divergent norms, the spiral of pressure, and the spiral of opportunity. Social Identity Theory is used to explain the mechanisms of each of these spirals. Our dynamic perspective contributes to a greater understanding of the development of corruption in organizations and opens up promising avenues for future research.
