Abstract : An important role for normative economics is to provide an analytical framework to evaluate social states. This evaluation is based on value judgments derived from moral views of members of the society. There exist three major approaches in normative ethics, which formalize many people's moral views. These are consequentialism, which focuses on consequences of actions; deontology, which focuses on moral duties, and virtue ethics. Virtue ethics has two important aspects: acquiring virtues (which we call the learning aspect) and human flourishing by using virtues and abilities (which we call the flourishing aspect). Among these, formal analytical frameworks have been developed for important aspects of consequentialism, deontology, and the flourishing aspect of virtue ethics. However, normative economics does not have a formal analytical framework for the learning aspect of virtue ethics. In this paper, we develop such a framework for models with endogenous preferences. We apply this framework to a rational addiction model and an intergenerational altruism model. We find that the introduction of virtue ethics can lead to very different policy recommendations than those based solely on welfarism, where emphasis is on maximizing social welfare functions. In contrast to the commonly held view, we find that incorporating virtue ethics into normative economic analysis may not always lead to greater government interventions.
