Alfred Marshall prägte die Begriffe Produzentenrente und Consumer surplus. Sie beschreiben die Differenz zwischen dem Preis am Markt und dem erwarteten Preis von einem Produkt. Die Konsumentenrente und die Produzentenrente stehen sich somit gegenüber und sind wichtige Bestandteile der ökonomischen Wohlfahrt.
Definition / explanation
The term producer surplus is important in economics as well as in mathematics. The producer surplus is the difference between the production costs and the sales price achieved on the market. Accordingly, producer surplus describes the profit a company makes on the market and is therefore desirable for manufacturers.
Producer surplus = sales - variable costs
Producer's rent in restricted competition
The producer surplus is particularly interesting under the conditions of restricted competition. In the case of optimal price discrimination, the provider receives the sum of the Consumer surplus and the producer surplus. In a competition he wins the welfare maximum.
However, he must know about the cost structure in order to correctly assess his profit situation. A monopoly must set the prices or the amount to get in one monopoly to increase the producer surplus in a profit-maximizing way. Most of the time, however, there is a decline in welfare, since an undersupply of monopoly goods usually occurs when there is an oversupply of goods.
example - For example, bed linen is sold at a price of 40 euros, which is the market price. Another provider would have offered the bed linen for 35 euros, as its production costs are lower.
Compared to the general retail price of 40 euros, the other provider saved 5 euros. The 5 euros saved then denote the so-called producer's pension.
