Ronald Coase, of Coase theorem fame, believed that markets are rarely efficient: "Coase argued that real-world transaction costs are rarely low enough to allow for efficient bargaining and hence the theorem is almost always inapplicable to economic reality."[1] In this case, the inefficiency persists because the costs of implementing a more detailed model would far exceed the benefits.
