Hybrid collusion : algorithmic pricing in human-computer laboratory markets
Normann, Hans-Theo; Sternberg, Martin - 2021
We investigate collusive pricing in laboratory markets when human players interact with an algorithm. We compare the degree of (tacit) collusion when exclusively humans interact to the case of one firm in the market delegating its decisions to an algorithm. We further vary whether participants...

Collusion and bargaining in asymmetric Cournot duopoly : an experiment
Fischer, Christian; Normann, Hans-Theo - 2018
In asymmetric dilemma games without side payments, players face involved cooperation and bargaining problems. The maximization of joint profits is implausible, players disagree on the collusive action, and the outcome is often inefficient. For the example of a Cournot duopoly with asymmetric...
