This research project collects contract level public procurement data from publicly available official sources in Hungary and a number of other EU countries such as Romania, Czech Republic, Slovakia and links the procurement data to further administrative databases such as company financial records. We have been working on Hungarian Public Procurement Database (MaKAB) since 2010 and database for other countries since 2012. The goal is to comprehensively map public sectors’ corruption risks and identify points of effective intervention. The project will provide a detailed corruption risk mapping on the level of public organisations per year between 2005-2013 and empirical results to explain the emergence of corruption risks and linking it to state capacity at the organisational level. This research project is conducted in close association with a large pan-European research project on anti-corruption policies (ANTICORRP) and a research project funded by the Hungarian Competition Agency looking at cartels in public procurement.
