Effectiveness, Efficacy, Efficiency

Giovanni Tuzet (Bocconi)


The work aims at bringing conceptual clarity on the notions of effectiveness, efficacy and efficiency of the law. It claims that effectiveness, efficacy and efficiency are conceptually independent notions and independent properties of law. As a consequence, there can be law that is effective but neither efficacious nor efficient, as there can be law that is efficacious but neither effective not efficient, and law that is efficient but neither effective nor efficient. In particular, the work discusses different notions of efficiency of the law.
