This article seeks to reconceptualize the notion of informality in the post-war context in order to investigate the neglected aspect of inequality which is associated with this kind of practice. It locates the problem of widespread informality in the social transformation triggered by a war that has been sustained by the post-war elite accommodation. Inequities created by a routine resort to informal arrangements in accessing assets and resources generate mistrust at the interpersonal, inter-group and institutional levels, sharpen a sense of discrimination and social injustice, and in the end, undermine post-war social reintegration. The argument draws on observations from Bosnia-Herzegovina.
