Deadweight Loss
Captions available
The idea
Deadweight loss is the social surplus that disappears when a market trades less than the equilibrium quantity, or more: the wanted trades that did not happen.
In practice
On the diagram it is the triangle between the curves, restricted quantity to equilibrium.
Where people slip
Deadweight loss is not a transfer: money moved from sellers to buyers still exists; the loss is value nobody receives.
