We report results from five Posted-Offer experiments with firm-specific quotas. The average contract price converges from below the competitive equilibrium. Thus, the independence of the contract price convergence path from surplus distribution is questioned iWe report results from five Posted-Offer experiments with firm-specific quotas. The average contract price converges from below the competitive equilibrium. Thus, the independence of the contract price convergence path from surplus distribution is questioned in our results.[+][-]
