Many conflict-affected countries are among the most corrupt in the world, and corruption is frequently reported as a major concern of local populations and foreign aid agencies during transition to peace. Tackling corruption is part of liberal peacebuilding, which seeks to consolidate peace through democracy and free markets economy. Yet liberalization policies may also foster corruption. Using a preliminary analysis of selected corruption perception indicators, this article finds tenuous and divergent support for post-conflict patterns of corruption. Three main arguments linking liberal peacebuilding with higher levels of corruption are then presented for further elaboration, and a research agenda is outlined.
