sunk costs those costs which have been incurred
but it has given zero utility or less utility then expected and the
cost can't be recovered or liquidate.we can understand this concept
with following examples
example -
- suppose your friend told you that a particular movie is worth
to watch which would give anyone a thrill experience.you are
impressed with your friend's review and thus went to watch the
movie and you found the movie dull and boring thus your utility
from the movie is zero or less than expected.but the theater is not
giving you the refund and thus you can't recover the cost
incurred.as a result this would be considered as sunk cost.
- suppose, a construction of a bridge on a river was executing
and all of a sudden government canceled the plan and thus the
resources employed like material,manpower etc are totally wasted
and it can't be recovered,moreover there is zero utility derived
from the bridge. this would also be considered as a sunk cost.
