DEPARTMENT OF ECONOMICS Working Paper The Liberal Ethics of Non- Interference and the Pareto Principle by Marco Mariotti and Roberto Veneziani Working Paper 2014-1 UNIVERSITY OF MASSACHUSETTS AMHERST The Liberal Ethics of Non-Interference and the Pareto Principle Marco Mariottiy Roberto Venezianiz January 28, 2014 Abstract We analyse the liberal ethics of noninterference applied to social choice. A liberal principle capturing noninterfering views of society and inspired by John Stuart Mill’sconception of liberty, is examined. The principle captures the idea that society should not penalise agents after changes in their situation that do not a¤ect others. An impos- sibility for liberal approaches is highlighted: every social decision rule that satis…es unanimity and a general principle of noninterference must be dictatorial. This raises some important issues for liberal approaches in social choice and political philosophy.
