Improving infrastructure in Romania has been a significant project in the past 25 years. Unfortunately, although large amounts of public funds were spent in the construction sector from 2007 to 2013 (an average of 6.6% of GDP), the physical results in terms of project quality and completion do not match this investment. One of the explanations for this is that public contracts were awarded to companies based on corrupted practices or political connections, the focus being on redistributing public money and not achieving high quality construction works.The present research points to the fact that statistical data analysis can be used in detecting corruption. The practice of single bidding and the tendency to establish political connections exist in the entire public procurement market. Nonetheless, non-EU funded contracts present a higher corruption risk. Only 1 out of 7 contracts receiving European funding were awarded to a single bidder, as opposed to 1 out of 4 contracts financed by the state budget. Still, 1 out of every 3 contracts won by a politically connected firm involved European funding. Data analysis also concluded that the number of contracts awarded per company can be explained by single bidding and the existence of a political connection in 44% of the cases. The agency-capture analysis revealed that favouritism in public procurement occurs especially at the local level and in state-owned companies. Most of the companies that “captured” contracting authorities are politically connected firms.At the same time, the case studies give an account of how firms’ owners go to great lengths to consolidate a network of relationships with high ranking officials so as to keep their doors open and contact political elites, but also various state institutions whose activity can favour or disrupt their companies’ economic well-being.
