A familiar example of a negative externality is traffic congestion. In principle, it should
be possible to internalize this externality by permitting drivers to negotiate rights to
drive during particular times. The most likely reason that this does NOT happen is that:
A) most individuals are unfamiliar with the Coase theorem.
B) the transaction costs associated with identifying and establishing communication
among the many interested parties would be prohibitive.
C) agreements arising from such negotiations could not be enforced, since the
Constitution guarantees all individuals freedom of access to all public roads.
D) lawyers would find a way to prohibit such negotiations unless they were actively
involved, and this would make transaction costs prohibitive.
