Opportunity cost

Opportunity cost or economic opportunity loss is the value of the next best alternative forgone as the result of making a decision.[1] Opportunity cost analysis is an important part of a company's decision-making processes but is not treated as an actual cost in any financial statement.The next best thing that a person can engage in is referred to as the opportunity cost of doing the best thing and ignoring the next best thing to be done.

Opportunity cost is a key concept in economics because it implies the choice between desirable, yet mutually exclusive results. It is a calculating factor used in mixed markets which favour social change in favour of purely individualistic economics. It has been described as expressing "the basic relationship between scarcity and choice."[2] The notion of opportunity cost plays a crucial part in ensuring that scarce resources are used efficiently.[3] Thus, opportunity costs are not restricted to monetary or financial costs: the real cost of output forgone, lost time, swag, pleasure or any other benefit that provides utility should also be considered opportunity costs. 公卫考场
