Robert Ellickson's book "Order Without Law" analyzes a case that provides a good test of Coase's theorem by studying neighboring areas with two different rules concerning whether landowners or cattle owners are responsible for damage caused by cattle. The evidence he found supported Coase's predictions, except that the distribution of wealth did not appear affected by the different rules (informal notions of equity tended to override the influences of the formal rules).
>>Coase's theorem is controversial among libertarians. Some will seize on
I think much of the problem is that libertarians like to make simplifying
assumptions such as negligible transaction costs.

Is this consequential analysis versus axiomatic principle dispute anything
more than a debate over the granularity at which to apply the analysis?
