A monopoly is a market with a single seller (called the monopolist) but many buyers. This represents a deadweight loss as their labour could have been contributing to the economy, but is not because of such laws. In this example, the supply curve shifts from E1 to E2 – which reduces demand and supply as the price has increased. Prices were unable to react to demand, so producers had little incentive to increase supply. This creates a deadweight loss for society as consumers are paying more than what the good takes to bring to market. With this new tax price, there would be a deadweight loss: As illustrated in the graph, deadweight loss is the value of the trades that are not made due to the tax.

A deadweight loss is where a trade is not made due to a disequilibrium in supply and demand. Deadweight loss is usually as a result of government intervention which creates a shift in the supply and demand curve – thereby pushing it out of its natural equilibrium. If we then add them together, we get the total deadweight loss. Price floors: The government sets a limit on how low a price can be charged for a good or service.

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. Therefore, to find the value of the deadweight loss (DWL) we will need to find the values for MC, P, Qc, Qm which we will do in the following example. 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. An example of a price floor would be minimum wage. Price floors: The government sets a limit on how low a price can be charged for a good or service. What these price floors do is set a minimum price, with the aim of ensuring the employee/producer has a guaranteed minimum income. However, what this does is artificially increase prices. If prices are too high, consumers will turn away and go elsewhere. After netting out the fixed cost, the lost social surplus equals the consumer surplus CS plus H. The fact that the monopolist does not capture all the social benefits from its entry distorts its entry decision. Example breaking down tax incidence.

This then calculates the deadweight loss between the two points on the graph after the supply or demand curve has shifted. With consumers attracted by lower prices, we see an artificial increase in demand. Deadweight loss also arises from imperfect competition such as oligopolies and monopoliesMonopolyA monopoly is a market with a single seller (called the monopolist) but many buyers. The buyer’s price would increase from P0 to P1 and the seller would receive a lower price for the good from P0 to P2. An example of a price floor would be minimum wage.
