“…From an economic view, sunk costs should be irrelevant for future decisions because decisionmakers are supposed to continue favorable projects, not unfavorable ones (Amelia, 2014).

Hereby, sunk cost is the determinant of an unfavorable project since it is irrecoverable and will not bring future benefits.…”
