Cartels remain widespread and constitute a major problem for society. Leniency policies reduce or cancel the sanctions for the first firm(s) that self-report being part of a cartel and have become the main enforcement instrument used by competition authorities around the world in their fight...

We propose a general framework for analyzing and comparing ownership structures with respect to creating incentives for co-operative behavior (e.g. efficient investment) in long-run relationships. We generalize models by Garvey (1995), Halonen (2002), and Baker, Gibbons and Murphy (2002) and...

In practical activity, the procurer can often decide to split the supply of a product in multiple contracts, or lots. This paper surveys some competitive tendering procedures for multiple contracts and discusses how the choice of the most appropriate format of competitive tendering for the...

Division in lots is one of the procurer's most crucial decisions. The number and the size of lots directly influences competition in the tendering process and thereby the procurer's budget and the quality of supply. This paper focuses on the effects the division of procurements into multiple...

Online "feedback mechanisms" - also known as "reputation systems" - have been implemented in the most important private e-markets, such as eBay, Yahoo!, Amazon to foster trust and cooperation among trading partners. In this paper we discuss the main issues relevant for the optimal design of such...

In softening price competition at the tendering stage, a bidding ring may jeopardize the buyer's effort to award a procurement contract at her most advantageous economic conditions. By exploiting the similarities between oligopolistic and procurement markets, we discuss how structural conditions...

Fostering whistleblowing through leniency and asymmetric sanctions is regarded as a potentially powerful anti-corruption strategy in the light of its success in busting cartels. The US Department of Justice started a pilot program of this kind in 2016. It has been argued, however, that...

We study differently framed incentives in dynamic laboratory buyer-seller relationships with multi-tasking and endogenous matching. The experimental design tries to mitigate the role of social preferences and intrinsic motivation. Absent explicit incentives, effort is low in both tasks. Their...

PPPs have been implemented broadly around the world in the infrastructure sector - water and sanitation, transports, energy and telecommunications - and, more recently, in the provision of public services -­ education, health, prisons, and water and waste management. Key aspects of the contract...

We test the overarching hypothesis that financial institutions face relatively milder fines due to financial stability concerns. To do so, we use an event study approach on a sample of 441 listed cartel members prosecuted by the European Commission between 1998 and June 2020. Our results suggest...
