As a normative Science, economics involves value judgement. It is prescriptive in nature and describes ‘what should be the things’. For example, the question like what should be the level of national income, what should be the wage rate, how can the fruits of national product be distributed among people, all fall within the scope of normative science. Thus, normative economics is concerned with welfare propositions. Some economists are of the view that value judgements by different individuals will be different, and thus for deriving laws or theories, it should not be used.
