Deadweight Loss

The loss of economic activity due to excessive taxation. For example, suppose a person on welfare is offered a job that pays more than he/she receives in welfare benefits. If taxes are too high, however, the person may find that his/her aftertax income is in fact lower than what he/she was receiving on welfare. The person might then rationally decide to stay on welfare. The deadweight loss is both the cost of keeping that person on welfare and the loss incurred from the economy at large from losing that person's production. It is also called the excess burden of taxation.

deadweight loss

the reduction in CONSUMERS’ SURPLUS and PRODUCERS’ SURPLUS that results when the output of a product is restricted to less than the optimum efficient level that would prevail under PERFECT COMPETITION. Fig. 36 shows the demand and supply curves for a product, and their interaction establishes the equilibrium market price OP. At this price, consumers’ surplus is shown as the diagonally shaded area ABP and producers’ surplus as the vertically shaded area APO. If output is restricted from OQ to OQ1, then the price paid by consumers would rise to OP1 and consumers’ surplus would be reduced by the amount ACE, while the price received by producers would fall to OP2 and producers’ surplus would be reduced by the amount ADE.

Deadweight loss is particularly likely to occur in markets dominated by MONOPOLY suppliers who restrict output in order to keep prices high.

This process artificially reproduces a situation similar to monopoly, where the outputs aren't optimal resulting in a social and economic dead-weight loss. Examples are airline companies or telecommunications providers capturing regulatory agencies in their favor, setting minimum tariffs at a higher level than what would be established by the market; construction firms influencing politicians to be awarded with contracts; companies using influence to reduce taxation.
261) is an accurate graphic representation of Dupuit's numerical examples but there is an obvious difference in the way that Dupuit and Hotelling measure dead-weight loss. Dupuit measures it as the difference between the net utility at the revenue maximizing point and the net utility at the government operated point (which covers average cost, estimated as being one franc for bridge C).
