Definition
What it costs the dependent party to stop depending on a system: money, time, records that must be reconstructed, relationships that must be re-established, and access that is lost. Exit cost is measured from the side of the person or organization the system's decisions land on, which distinguishes it from substitution cost, the institution's own cost to replace the system. The two move independently; an institution can be free to replace a system its population cannot afford to leave.
It matters because a party who can leave at acceptable cost bears a system's errors only until they leave, and a party who cannot bears every error for as long as the system makes it. Exit cost therefore measures how much of the institution's correction capacity is the only correction there is, and how far the population's silence can be read as anything other than the silence of people with nowhere else to go. It is what turns a right of exit from a clause into a quantity, and it rises by drift where records accumulate in the system's format and alternatives are not maintained.
