This research project collects contract-level public procurement data from publicly available official sources in Hungary and several other EU countries, including Romania, the Czech Republic, and Slovakia. It links the procurement data to additional administrative databases, such as company financial records. We have been working on the Hungarian Public Procurement Database since 2010, and the database for other countries since 2012. The goal is to map public-sector corruption risks and identify effective intervention points comprehensively. The project will provide detailed corruption risk mapping at the level of public organisations for the years 2005-2013, along with empirical results explaining the emergence of corruption risks and linking them 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 Authority examining cartels in public procurement.
