This paper reports results from an experiment studying how fines, leniency programs and reward schemes for whistleblowers affect cartel formation and prices. Antitrust without leniency reduces cartel formation, but increases cartel prices: subjects use costly fines as (altruistic) punishments....

This paper presents results from a laboratory experiment on the channels through which different law enforcement strategies deter cartel formation. With leniency policies offering immunity to the first reporting party a high fine is the main determinant of deterrence, having a strong effect even...

Flexibility - the ability to react swiftly to others' choices - facilitates collusion by reducing gains from defection before opponents react. Under imperfect monitoring, however, flexibility may also hinder collusion by inducing punishment after too few noisy signals. The combination of these...

We study social dilemmas in (quasi‐) continuous‐time experiments, comparing games with different durations and termination rules. We discover a stark qualitative contrast in behavior in continuous time as compared to previously studied behavior in discrete‐time games: cooperation is easier...

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...

We study interactions with different durations and termination rules in a (quasi) continuous-time prisoner’s dilemma experiment. We find that cooperation is easier to achieve and sustain with deterministic horizons than with stochastic ones; end-game effects emerge, but subjects postpone them...
