The choice between quantity and price in order to stabilize collusion is modeled here. It is shown that this relocates the prisoners’ dilemma backwards, from the market stage to the stage where the market variable is chosen in order to sustain collusion, and where discount rates appear as the...

Danish ready-mixed concrete is produced in regional oligopolies. Firms rely on price discrimination through secret discounts. The antitrust authority interprets this as lack of competition and has decided to activate its chief weapon against dormant competition: To make the market more...
