These alter the incentives to the producer to supply the market, and the consumer to demand goods from the market. So the consumer ends up paying more than they would under a competitive environment. So the deadweight loss is the difference between the marginal benefit and the marginal cost for all these units here. A bus ticket to Vancouver costs $20, and you value the trip at $35.

The law of supply depicts the producer’s behavior when the price of a good rises or falls. Those price limits then discourage suppliers, who supply less at the lower price. To calculate deadweight loss, we must find the area highlighted in grey below which refers to both the deadweight loss to the consumer and the producer.
