Collusion Risk in Corporate Networks

Isabela Villamil, János Kertész, and Mihály Fazekas (2024) Collusion Risk in Corporate Networks. Scientific Reports, 14.

We use a network-based approach to study the relationship between ownership links and bidding behavior in procurement markets. We build temporal multiplex networks based on firms’ ownership and co-bidding ties to find network measures that may …

Corruption Risks in Emergencies

Fazekas, Mihály & Nishchal, Shrey (2023) Corruption Risks in Emergencies. In Elgar Concise Encyclopedia of Corruption Law. Chapter 38. Edward Elgar Publishing.

Following disasters, governments need to implement a range of responses, including the procurement of essential supplies in a short time to fulfil urgent needs. Good procurement principles such as open competition and value for money may hamper timely emergency response. Therefore, emergency clauses, which allow for deviations from open competition, are a standard component of government procurement laws. …

Elections and Corruption: Incentives to Steal or Incentives to Invest?

Fazekas, M., Hellmann, O. (2023) Elections and Corruption: Incentives to Steal or Incentives to Invest?. Studies in Comparative International Development. 

By now, most political systems around the world hold regular multiparty elections of different quality and type. However, we know relatively little about the effect of elections on corruption, especially in high-discretion, public procurement contracts implementing development aid. To address this gap in the literature, we employ unmatched comparisons and matching estimators to analyze a global government contracting dataset that …

Wittberg, E. and Fazekas, M. (2023). Firm performance, imperfect competition, and corruption risks in procurement: evidence from Swedish municipalities. Public Choice 197, 227–251.


Previous research has shown that corruption risks may distort market incentives in high-risk contexts. However, there is a dearth of evidence on the potential impact of corruption in settings characterized by low corruption and high-quality institutions. Against that background, this paper delves deeper into the alleged consequences of corruption by examining the link between corruption risks

Agency independence, campaign contributions, and favouritism in US federal government contracting

Fazekas, M., Ferrali, R., Wachs, J. (2022). Agency independence, campaign contributions, and favouritism in US federal government contracting. Journal of Public Administration Research and Theory, muac026.

The impacts of money in US politics have long been debated. Building on principal-agent models, we test whether and to what degree companies’ political donations lead to their favoured treatment in federal procurement. We expect the impact of donations on favouritism to vary by the strength of control by political principals over their …
