In economics and business decision-making, a sunk cost (also known as retrospective cost) is a cost that has already been incurred and cannot be recovered. [ 1 ] [ 2 ] Sunk costs are contrasted with prospective costs , which are future costs that may be avoided if action is taken. [ 3 ]
From the traceability source of costs, sunk costs can be direct costs or indirect costs. If the sunk cost can be summarized as a single component, it is a direct cost; if it is caused by several products or departments, it is an indirect cost. Analyzing from the composition of costs, sunk costs can be either fixed costs or variable costs.
A costly signal in which the cost of an action is incurred upfront ("ex ante") is a sunk cost. An example of this would be the mobilization of an army as this sends a clear signal of intentions and the costs are incurred immediately. When the cost of the action is incurred after the decision is made ("ex post") it is considered to be tying hands.

Of these, sunk costs, time investment, decision maker experience and expertise, self-efficacy and confidence, personal responsibility for the initial decision, ego threat, and proximity to project completion have been found to have positive relationships with escalation of commitment, while anticipated regret and positive information framing ...
The fixed cost refers to the cost that is incurred regardless of how much the firm produces. The variable cost is a function of the quantity of an object being produced. The cost function can be used to characterize production through the duality theory in economics, developed mainly by Ronald Shephard (1953, 1970) and other scholars (Sickles ...
To construct an optimality model, the behavior must first be clearly defined. Then, descriptions of how the costs and benefits vary with the way the behavior is performed must be obtained. [1] Examples of benefits and costs include direct fitness measures like offspring produced, change in lifespan, time spent or gained, or energy spent and gained.
Evolutionary economics is a school of economic thought that is inspired by evolutionary biology.Although not defined by a strict set of principles and uniting various approaches, it treats economic development as a process rather than an equilibrium and emphasizes change (qualitative, organisational, and structural), innovation, complex interdependencies, self-evolving systems, and limited ...
