Rational and Ethical Individuals :

The Formalization of Harm Principle and some Implications

Abstract

     In this paper, we require each individual not only to be rational, but also ethical. We assume some persons who adopt “harm principle” and never take an action which worse off other persons' welfare. It is clear that all equilibria of such persons' non-cooperative games are Pareto-efficient. Then, the “harm principle” is community-oriented, not liberty-oriented like libertarians assert.
