We model networks of relational (or implicit)contracts, exploring how sanctioning power and equilibrium conditions change under different network configurations and information transmission technologies. In our model, relations are the links, and the value of the network lies in its ability to...

Following Bernheim and Whinston (1990), this paper addresses the effects of multimarket contact on firms ability to collude in repeated oligopolies. Managerial incentives, taxation, and financial market imperfections tend to make firms objective function strictly concave in profits and market...

The paper addresses the effects of the separation of ownership and control on long-run competition in oligopolies. It finds that when managers have the preference for smooth time-paths of profits revealed by the evidence on "income smoothing," manager-led firms can sustain any collusive...

In this paper we investigate the effects of risk preferences and attitudes towards risk on optimal antitrust enforcement policies. First, we observe that risk aversion is negatively correlated with playersÂ’ proclivity to form a cartel, and that increasing the level of fines while reducing...

Recent research on central bank governance has focused mainly on their monetary policy task. As the sub-prime loan market turmoil reminded us - central banks play a crucial role in financial markets not only in setting monetary policy, but also in ensuring their soundness and stability. In this...

Feedback mechanisms that allow partners to rate each other after a transaction are considered crucial for the success of anonymous internet trading platforms. We document an asymmetry in the feedback behaviour on eBay, propose an explanation based on the micro structure of the feedback mechanism...

The paper reviews the recent evolution of leniency programs for cartels in the US and EU, surveys their theoretical economic analyses, and discusses the empirical and experimental evidence available, also looking briefly at related experiences of rewarding whistleblowers in other fields of law...

Collusive agreements and relational contracts are commonly modeled as equilibria of dynamic games with the strategic features of the repeated Prisoner's Dilemma. The pay-offs agents obtain when being ‘cheated upon’ by other agents play no role in these models. We propose a way to take these...

I characterize the effects of empirically observed managerial incentives on long-run oligopolistic competition. When managers have a preference for smooth time-paths of profits – as revealed by the empirical literature on ‘income smoothing’ – manager-led firms can sustain collusive...

Procurement awarding mechanisms based on average price have been advocated to soften price competition and reduce cost overruns. We show that their theoretical support is shaky. When the bid closest to the average is awarded, firms submit identical bids, making the selection extremely costly and...
