The Technology of Public Goods, Externalities, and the Exclusion Principle

Presented here are some notions which we hope will help researchers in their attempts to model various aspects of the complex situations which, currently, come tinder the heading of "externality problems."

The links between these activities can then be used to characterize types or classes of externality problems
