If transaction costs are low, the efficient activity will occur, either the rancher or
railroad installing fences to protect from rampaging cattle and/or sound insulation
with trees, or if it is cheaper, fewer train trips per day. The cheapest or most efficient
solution will happen, regardless of who is assigned the original property right - ANS-
The Coase Theorem works best in places that transaction costs for contracts among
people is low. Often in the world of torts and externalities both parties can claim that
they have rights to impose on others. One case is that of a railroad that is noisy and
scares the cattle and the rancher whose cattle sometimes wander in front of moving
trains causing damage to them and the train. What does the Coase say would happen?

b. If transaction costs are low, the efficient activity will occur, either the rancher or
railroad installing fences to protect from rampaging cattle and/or sound insulation
with trees, or if it is cheaper, fewer train trips per day. The cheapest or most efficient
