Consideration was originally an important concept in Anglo-American contract law, and its connotation is the monetary price paid by one party to the other party in exchange for the promise of doing something, or the price of obtaining such a promise.
It means that when one party obtains certain benefits, it must pay the corresponding price to the other party.
Consideration was originally the principle of validity in Anglo-American contract law. Its original meaning is "in exchange for another person's promise to do something, what someone pays is not necessarily the price of money", perhaps it is "the price of buying a promise"
From the legal point of view, consideration is an equivalent paid promise relationship, while from the economic point of view, consideration is an offer made by two or more equal subjects to solve this conflict through a compromise relationship between two or more equal subjects when their respective interests are in the best condition and are not accepted by the other party.
In other words, when the legal relationship between two or more equal subjects conflicts due to the adjustment of economic interests, the concessions made by both parties to the conflict. This concession can also be understood as a kind of compensation for the losses caused by emphasizing their own interests.
Consideration means that one party gains benefits and the other party suffers losses because of the contracting behavior between the two parties. The system of consideration is a unique system in British contract law and a necessary prerequisite for the establishment of all contracts except sealed contracts.
The so-called consideration is to exchange one's promise for the other's promise, or let the other do something beneficial to oneself, with one's reciprocal behavior as a guarantee.
